How to Classify the X-Ray Security Detector?

After the inspected goods have been exposed to X ray irradiation, the larger the density of matter and the atomic number are, the greater the X-ray absorption rate will be. And the protein, carbohydrate, fat, water and bones (calcium), glass (silica), metal, and the composition contained in the food, is also different to X-ray absorption ratio. The X-ray security detector is implemented according to the principle mentioned above.

When products is sent to the X-ray irradiation area, detection device will automatically determine X-ray transmission ratio. Due to foreign bodies in food ingredients can absorb more X ray energy than food composition, therefore, when the products containing foreign body exposed to the X ray radiation, the energy will be absorbed a lot. The X-ray machine will measure the beam intensity of content, so as to detect if the objects is different from the product itself in the material composition of foreign body.

Designed for highway, railway, customs, airports, ports and public safety testing, it is widely used to detect the human body and whether the luggage contains knives and guns.

It can be classified as follow:

A, portable X-ray security detector

Main features:

1. mainly adopts high performance vacuum ceramic image intensifier, aesthetically pleasing and has a large clairvoyant object radius.

2. It doesn't need a dark room to form the clear picture. Low leakage radiation dose, without any protection.

B, the conveyor x-ray inspection detector

This type of product has a large appearance and a conveyor belt. Usually, it is mainly used for on-line detection of the foreign body in the industrial products, such as metal, stone, mud, plastic, glass, etc.

This type of products is also the mainstream of domestic products. The efficiency is higher, and it is more powerful. If it has detected the content of products that are foreign bodies, the machine will automatically reject it, which greatly improved the work efficiency.

This type of X-ray security detector is not expensive as it used to be. Price varies according to the design, material, functions, after-sales service etc.

Main features:
1. sound and light alarm: It will send out the sound signals and alarm lamp when it is similar to the conditions.

2. the network interface: It can connect multiple terminals at the same time when checking luggage.

3. safer ray: Its ray emission is controlled automatically to avoid the mistake.

4. only one key to turn off: Rotating the key, and the equipment will shut down automatically and safely, which means that it does not need complex multistep operation. It is more convenient and concise.

5. eagle eye: The current amplification area can be easily seen. - See more at: http://www.eastimagesecurity.com/IndustryNews/How-to-Classify-the-X-Ray-Security-Detector.shtml

Introduction to Different X Ray Machine Parts

Parts of an X-Ray Machine

An x-ray machine is a complicated device which can be untarnished in a various of circumstances around the world, which has the ability to penetrate hard objects, they are used for several purposes such as airport security checkpoints to check into bags, or in the medical community to check out where the broken bones or problems within the body exit. All of these above are components that are vital to the inner workings of an x-ray bag scan equipment regardless of which type of X-ray.

--Power Source
A high voltage power source is necessary to operate an x-ray machine, often between 30 and 150 kilovolts relying on the type of x-ray being taken. In the vacuum tube, the voltage can be used to quicken the electrons and is often pulled from 1 microsecond to 1 full second. The high power source of the x-ray machine controls the penetration of the x-ray itself, and thus the overall contrast of the image, with the voltage of the current and exposure time having an vital influence on the dose and darkness of the image.

--Control Unit
To manage the current, voltage, and time of exposure isn't unnecessary for the control unit of the X-ray luggage scanner . Intensity of radiation can change remarkblely relying on whether you are using the machine to render x-ray stills of body parts or using it as a security monitor, what's more,there is a voltage control with a display, which can allow you to adujst yourself in the anode itself to change the style of radiation energy that is to be released.  For the control unit ,there is also a timer to control the pulses and duration of the exposure, shutting the current off when the task of the radiation exposure has been finished .

--Vacuum Tube
Vacuum tube is another name of x ray tube actually and it is one of the important integral X-ray security Inspection equipment parts which works by ionizing radiation with wavelengths shorter than ultraviolet light. Well, the cathode within the equipment can emit electrons into the tube through the vacuum tube or x ray tube actually.

New Airport X-Rays Will Scan Bodies, Not Just Bags

PHOENIX, Feb. 23 — X-ray vision has come to the airport checkpoint here, courtesy of federal aviation security officials who have installed a new device that peeks underneath passengers’ clothing to search for guns, bombs or liquid explosives.
The new X Ray baggage scanner on sales , which went into use on Friday at Phoenix Sky Harbor International Airport and will be tested later at airports in Los Angeles and New York, will screen only volunteers, at least initially. Transportation Security Administration officials want to make sure the machine is reliable and fast enough to replace the traditional pat-down — and that it does not provoke too many protests.
Security officials examining the head-to-toe images work in a closed booth, hidden from public view, agency officials said. Special “privacy” software intentionally blurs the image, creating an outline of a body that is clear enough to see a collarbone, bellybutton or weapon, but flattens details of revealing contours.
Kenneth Johnson, 64, of Mesa, was the first passenger screened on Friday in Phoenix. He said he had titanium implants in both shoulders and one knee that set off alarms at checkpoint metal detectors.
“I’ve been all over the world; I’ve been strip-searched,” Mr. Johnson, who was traveling to Florida, told an Associated Press reporter. “This was very easy.”
Others found the scans objectionable.
“I think that is a violation of people’s personal rights,” said Kara Neal, 36, a mental health counselor on her way to Philadelphia. She was not asked to undergo the screening, but said she would have refused. “I would rather take a pat-down than go through this,” she said.
Lawyers for the American Civil Liberties Union have raised similar objections, calling the High sensitivity digital walkthrough metal detector a “virtual strip-search,” and have urged Congress to prohibit its use for routine screening.
The vending-machine-size device, which costs about $110,000, will be used only when passengers are pulled aside for a more thorough check, known as secondary screening, after passing through a metal detector. Other scanning machines will be installed this year at Los Angeles International Airport and at John F. Kennedy International Airport in New York.
While security agency officials say the machines, known as SmartCheck, pose no health hazards, some experts disagree. The machine, manufactured by American Science and Engineering Inc. of Billerica, Mass., generates about as much radiation as a passenger would get flying for about two minutes at about 30,000 feet, or in technical terms, fewer than 10 microRem per scan, according to security agency and company officials. The machine is already being used in some prisons, by United States customs and at Heathrow Airport in London.
Dr. Albert J. Fornace Jr., an expert in molecular oncology at Georgetown University Medical Center, said such a low dose was inconsequential, even for pregnant women.
“Obviously, no radiation is even better than even a very low level,” Dr. Fornace said. “But this is trivial.”
But David J. Brenner, a professor of radiation oncology at Columbia University, said that even though the risk for any individual was extremely low, he would still avoid it.
“The question is, Do you want to add to your already existing risk?” Professor Brenner said, recommending that pregnant women and young children, in particular, avoid the device. “There are other technologies around that can probably do the job just as well without the extra radiation.”
The machine beams a low-energy baggage inspection supplier at the passenger, which after it bounces off the surface of the skin is processed by computer software that highlights metals or elements like nitrogen that are found in explosives or weapons.
The X-ray is not strong enough to penetrate much beyond the skin, so it cannot find weapons that may be hidden in body cavities.
“A lot of people aren’t really comfortable with a pat-down,” said Ellen Howe, a security agency spokeswoman, “so they may find this to be an alternative they may appreciate.” She added that the X-ray images would be destroyed immediately.
Aviation security officials are rushing to bring new screening devices to airports because of the London-based plot last summer to use liquid explosives to blow up airliners headed to the United States.
The devices now used at the nation’s airports, the narcotics detecting for carry-on bags and the metal detector for passengers, rely on 1950s-era technology that cannot reliably detect liquid or plastic explosives.
Earlier efforts by the federal security agency to introduce more advanced checkpoint technologies have stumbled, including the so-called puffer machines, which blow air on passengers to search for minute traces of explosives.
After installing 94 of the machines at 37 airports, officials suspended the program last year, saying the devices broke down too often. More puffer machines may be bought if the problems can be resolved.
Officials intend to try other alternatives, like a so-called millimeter wave machine that uses harmless radio waves, instead of X-rays, to do a full body scan.
Ms. Howe said that until the tests on the SmartCheck were complete, it was unclear how widely used the machines would be. “We are committed to testing it,” she said. “But we are not committed to deploying it widely until we learn more.”

Security Apparatus Installation Eliminates Hazards

There are a lot of security inspection equipment and when it comes to scanning machines, a number of different technologies are involved including the structured light and the computational tomography. In the same vein, the usage of security apparatus vary from each other and a case in point are laser scanners and coordinative measurement machines which are constructed on the basis of similar principles yet function differently. In general, most security apparatus developed in the past three years get the security related data directly from the topological measurement and the data are often converted into a commonly seen format such as a computer aided design model, a highly realistic faced mesh, or non-uniform computed surfaces.

To be more specific, in general one of the main objectives of security apparatus installation is to get the free form shapes out of the body surface and the layer of cloth that covers the human body in important security ports. Then the data can be measured and analyzed to produce free form shapes of many different types. However, it is not an easy task to get the scanned surface images of a certain person suspected to have carried illegal items and it requires the use of an advanced high definition X-ray security Inspection equipment in order to scan the body with clothes. After that, the collected data can be processed with the help of the graphic software. Therefore, we may conclude that the usage of security apparatus mainly takes three steps including the acquisition of security data, data processing and image generation.

Thus, the usage of security inspection machine might be defined as depicting the space between the body and clothes in an exact manner. Security data, often in the form of raw point cloud data, can be obtained within five minutes if the security system works well and you do not have to worry about a great deal of noise frequently experienced in traditional security apparatus. This is because the modern security apparatus can help security administrators to reduce the data size while at the same time, keep the data entirely true to the original shape of the person or object that has been scanned.

At the same time, images can be produced with the processed data, which will lead to the further generation of surfaces and models. Another interesting thing about xray baggage scanner is that the above mentioned processes are completely automated until the entire data base is connected with the network and the meshes will be cleaned up if there are any inconsistent edges so as to ensure that the free form models are constructed from the clean meshes. As a matter of fact, there are random quality checks of security apparatus to remove products that are below the par.

Body Scanner Price on the Decrease

Body scanner price at present is somewhat lower than three years ago thanks to the development of the intelligence technology but the most interesting thing about body scanner price is perhaps the fact that advanced body scanners are capable of working at a range of up to ten meters. In other words, even though the detectors in the body scanner can be quite unobtrusive in theory, they make a record and scan people quietly as they shuffle through the only paths laid out for them at such places as the airport security gate.

Some companies have already expressed interest in the body scanner price and its technology while some researchers hope to create better body scanner prototype in the near future. In spite of the reduced body scanner price, the new technology concerned could be tuned to find out all sorts of compounds that have different probe frequencies. As a matter of fact, it is highly possible that everyone has a certain amounts of compound items on us yet law abiding people do not have to worry about the potential alarm set by the body scanner.

Transistor makes up a large part of the body scanner price and it will filter different signals after receiving them from the main monitor. After that, it will send the signal to land mobile device number one nearby which is largely used as a receiver whose pin functions as a minor database. Then the received signal will be transmitted to the second land mobile device number two which serves as an amplifier so that the signal can be magnified via the integrated circuit.

Another important parts of the body scanner price at present are the capacitor and resistors which are used for matching with the circuitry. What is more, some kinds of body scanner may be installed with infra-red LEDs and the lighting power mainly comes from slender band structures above the ground.

In general, infra-red rays not only spread in all directions but also along straight lines in the forward direction, featuring secondary wavelets when they collide with any obstacles in its path. With the increasing availability of the infra-red ray technology, body scanner price witnesses a slight decrease. To be more specific, when IR rays are emitted from the LED lights, they are designed to move at a special angle in the direction of the transistor so that if any obstacle interferes in its path, the IR rays will be cut. As a result, secondary wavelets will be produced in the opposite direction. What is more, photodiode also accounts for part of the body scanner price, which is a type of photo detector capable of converting light into a current or voltage and is used for the protection of circuit.

What Is Nowadays X ray Machines Application

Thanks to the greatest discovery of Hand Hold liquid detector by Wilhelm Rontgen in 1895. From then on, many scientists experimented and aided in developing X-ray technology. Various X-ray machines were invented and they became a kind of the most useful and powerful tools with an increasing needs in modern society. You can find them anywhere in both industrial and medical fields, and in commercial and government settings.

Besides the medical usage, X Ray baggage scanner on sales  have another significant application which lies in transportation security. No matter where you travel to and which means of transportation you choose, you will meet the security X-ray machines in and out of your country, and you must focus on something about types of security X ray systems. There are many types of them at bus stations, airports, and railway stations, metro and underground stations. Free standing security luggage X-ray machines in different sizes inspect both your carry-on bags and checked luggage. That’s the common usage of security X-ray system which ordinary people may engage in or have knowledge on.

Due to the needs of public safety, the security X-ray technology is developing rapidly these years. Similar X-ray devices which have different types of X-Ray generators are used for different applications. They are perfect for use on various objects by government agencies, corporate security teams, law enforcement agencies, customs, security check points, border control and prisons etc. They also can be used for some important events and venue security.

Authorities usually use X-ray machines and other related security inspecting systems to detect weapons, stowaways, illegal drugs, and other contraband. There’s an auto Hand Held liquid detector suitable for vehicles up to the size of a small van and it can be rapidly set up and operational. When a target vehicle goes through the single pass which has an X-ray scanner, the security personnel could have a detailed view of the inside of the vehicle in a single scan. With 3 digital x-ray imaging technologies, the operator can view the images clearly from a remote laptop in order to detect any suspicious objects. Furthermore, some real-time portable X-ray machines were designed to meet a wide range of needs on the field operative in security and others. They can help security personnel to make quick-reaction on potential threats and possible risks.

Actually, public safety is not only the matter of our government, but also the matter of our own. It is reported that a parcel which was polluted by poisonous chemicals killed several people last year in China. The related companies who send it and who delivered it took the responsibility. Supposing that the express companies use mail/package scanning devices which employ x-rays before they delivering them, this killing should be happened then? Unfortunately, for most of the express companies in China, the procedure of delivery is still a hangover. It is hoped that they will have effective X Ray baggage scanner company for inspecting potentially harmful items and contraband in the near future.

There’s still more ample scope for the applications of security X-ray machines and they will bring more benefits in modern society as they always do.

Hand Portable Metal Scanner Has Different Applications

Metal is nearly everywhere in our lives. Even though we may not feel the existence of it, metal plays an irreplaceable role in this world. Metal is on our clothes, in our laptop, on the bus and on the road. However, metal can also bring harmful influence to our lives. As a result, the detection of metal is quite important and necessary.

Hand Hold liquid detector are divided into many types. Some metal detectors are produced for security check. For instance, it is common to see the staffs in airports, train stations, subway stations, embassies and customhouses hold different application of X Ray baggage scanner on sales. They use the scanner to detect whether there is dangerous metal item hidden on people. With this procedure, the safety of people will be ensured. It’s really easy to handle because the hand metal scanners are able to regulate and adjust themselves automatically, so that operators don’t need to change any parameters of the scanner. What they are supposed to do is only moving the scanner close to people to be detected. Considering that the working period of the operators may be quite long, the scanner shouldn’t be heavy. Fortunately, the designers are considerate and they have thought about this issue. After several generations of improvement, hand metal scanner becomes lighter and lighter. As a result, the operators can use it with ease and convenience.

Another typical case is the application in baggage detector factory archaeology. There is so much unknown treasure and so many relics underground. Metal’s properties are stable, so they can still exist after so many years underground.

Most of the relics are metal and it’s significant to looking for them and digging them out. With the help of hand metal scanner, historians are able to detect the existence of metal items and determine the location of the metal items accurately. Since the different application of Hand Held liquid detector is light and portable, historians are able to carry it conveniently. So that historians can look for metal items in the wild and find out the remaining trace of brilliant history.

Here is an example that is close to students. In mainland China, the college entrance examination is of great importance and significance. So it is clear that every student wants to perform as well as they can because they only have one chance a year. However, some lazy students who are not willing to study hard also desire to enter excellent university. Without enough knowledge to work out difficult problems, they think about using electronic devices to cheat. After many cases of cheating with electronic devices are reported, narcotics detecting scanners are introduced into the examination rooms. Before entering the examination room, students need to be detected by hand metal scanner. As a result, we ensure fair treatment for every student.


As we can see, the application of hand metal scanner is really wide. It makes our lives convenient and better.

You Can Know Working Principle of X Ray Machine

The basic line control instruments by the oscillator, phase shift and amplitude bridge, selected frequency amplifier , detector ultra-low frequency amplification emitter fit one-shot swing, power supply.

Portable metal detector (grounds 15kHz oscillator generates a sinusoidal voltage detection coil fed detection coil by a master transmitter coil) basic principle is important. It includes two vice- ring and the input transformer, output transformer. Vice- ring located on the main transmitter groups on both sides of laps, lap distance equal to the primary transmitter and symmetrical, and cross-linked with each other to form a differential coil. When 15 kHz sine wave oscillator generates a sinusoidal alternating voltage of the transformer is fed through the input master transmitter coil, thus producing 15 kHz alternating magnetic field, and two pairs of the cutting ring in the main loop by transmitting a large alternating current.

Because of the two vice- lap main launch yet another lap distance symmetrical cross chain, while the induction of an equal magnitude but opposite direction (phase difference of 180 °) of the EMF 15kHz offset each other ( due to the relationships that we cannot process the two deputy circle the main circle done completely symmetrical, and shielding materials outside influence, there is always a mV output transformer unbalanced signal output level , and we want it as small as possible ). When no metal probe into the circle , only a faint 15kHz signal output amplitude imbalance, this signal after amplification by a DC voltage detector becomes blocking capacitor being blocked, you cannot enter the post-amplifier, then the instrument still in a relatively stable state.

Once the metal into the detection coil, metal is at 15kHz alternating magnetic field, generated EMF , eddy current phenomena, so the relative balance detection coil is destroyed, and produce low-frequency pulsating electrical potential difference, this pulsating potential difference is set out in the original such as the amplitude imbalance signal input to the amplifier amplifies. When you buy metal detector, according to portable metal detector, metal signal through the first-stage amplifier, 3000 a magnitude has been amplified 4000 times, and then into the detector to remove the useful signal from the low-frequency amplifier unbalanced signal sending trade deficit, but also get more than 1000 -fold magnification. At this point the signal from the original metal microvolt signals become amplified by several orders of magnitude volts, and after reaching the trigger voltage level trigger, the trigger work led relay, an alarm signal, and control objects required for automatic control. For example, cut off the power supply load, lit lights, sound signals, etc., based on these, we can determine the presence or absence of metal.


Portable metal detector, which possesses security screening system, is designed to detect people or objects carrying metal objects. It can detect the parcels, baggage, mail, etc. within the fabric brought weapons, explosives or small metal objects people carry. You should know particularly sensitive to the appearance of its surface make operation simple and easy. Superior ring sensor type hand probe.

Provide You With Luggage Detector of Any Color and Shape

World leading luggage detector factory has a high standard of reliability in the tracked trajectory in terms of evaluating the overall detection event in which an alarm will be triggered if the goods inspection confidence score surpasses a given threshold. However, according to a number of luggage detector factory, this threshold can be largely adjusted by the detector users in order to achieve different degrees of security system sensitivity since the work flow and load might differ in a variety of cases. What is more, different luggage detector factory is basically devoted to different kinds of detection products.

For instance, Hand Hold liquid detector  makes use of the foreground sampling method which is capable of localizing the suspicious luggage while some others may utilize the luggage selective modules according to the experimental results so as to further indicate the alarm timing. To be more specific, during the first stage of the luggage detector factory production system, the detection sampling is in generally carried out in an attempt to localize static luggage and items within the camera view. At the same time, some of the abandoned luggage as well as items might be scanned according the detection program set by the world leading luggage detector factory.

High sensitivity digital walkthrough metal detector technique is an imitation of the human ability to focus its attention on some objects of interest, which is especially true with the objects that can be identified by logical reasoning of the luggage detection devices, including some luggage items. Therefore, other irrelevant objects can be ignored by the luggage detector factory within the same scene when producing the luggage detectors.
On the other hand, a number of luggage detector factories make use of the luggage appearance based models in locating and analyzing luggage items in question so their products can deal with an array of luggage of any color and shape in an easy manner and will not be influenced by different viewing angles. This is because questionable luggage as well as abandoned luggage is assumed to remain static for more than ten seconds in a row so that at least five video clips will be collected from the luggage detector samples so the detection performance standard can be ensured.

Another aspect of the China X Ray baggage scanner company is that its background model is often constructed using selected detection frames from the standard test sequences in which the luggage images and data are minimized in the first place so as to make the detection and analysis processes faster. Therefore, in situations where the luggage detector factory background frames are unavailable, foreground clutter is essential even though the average number of selected frames is already comprised in the package.

About LF Technology and Features

Very low frequency (VLF), also called induction balance, is possibly the most popular detector technology used today. In a VLF metal detector, there are two separate coils:

· Transmitter coil – This is the outer coil loop that contains a coil of wire. Electricity is sent along this wire in different directions thousands of times per second. The number of times that the current’s direction changes each second is called the frequency.

· Receiver coil – This inner coil contains another loop of wire. This wire acts as an antenna to pick up and amplify the frequencies coming from objects being scanned. The current moving through the transmitter coil creates an electromagnetic field. The polarity of the magnetic field reaches outward form the coil and changes directions in step with the frequency. This means that the magnetic field is constantly pushing out and back again as the subject is being scanned.

As the magnetic field pulses back and forth, it interacts with any metallic object it encounters. This causes the hidden item to generate weak magnetic fields of its own. The polarity of the object’s magnetic field is opposite from that of the transmitter coil. If the transmitter coil’s field is pulsing out, then the object’s field is pulsing back.

The receiver coil is completely shielded from the magnetic field generated by the transmitter coil but it is not shielded from magnetic fields coming from target object. So when the receiver coil passes over an object giving off a magnetic field, a small electric current travels through the coil. This current fluctuates at the same frequency as the object’s magnetic field. The coil amplifies the frequency and sends it to the control box of the metal detector, where sensors analyze the signal.

The metal detector can determine the approximate size of the object based on the strength of the magnetic field it produces. The closer to the surface an object is, the stronger the magnetic field picked up by the receiver coil and the stronger the electric current generated. The smaller or farther below the surface the object is, the weaker the field. Beyond a certain size or depth, the object’s field is too weak and is undetectable by the receiver coil.

How does a VLF metal detector identify different metals? It relies on a phenomenon called phase shifting. Phase shift is the difference in timing between the transmitter coil’s frequency and the frequency of the target object. This deference can result from a couple of things:

· Inductance – An object that conducts electricity easily (is inductive) is slow to react to changes in the current. You can think of inductance as a deep river: Change the amount of water flowing into the river and it takes some time before you see a difference.

· Resistance – An object that does not conduct electricity easily (is resistive) is quick to react to changes in the current. Resistance would be a small, shallow stream: Change the amount of water flowing into the stream and you notice a drop in the water level very quickly.

This means that an object with high inductance is going to have a higher phase shift, because it takes longer to change its magnetic field. An object with high resistance is going to have a lower phase shift.

Phase shift provides VLF style metal detectors and body scanners with an ability called discrimination. Since most metals differ in inductance and resistance, a VLF metal detector examines the amount of phase shift. This is done using a pair of electronic circuits called phase demodulators and they compare the phase shift with the average for a particular type of metal. The detector then notifies you with an audible tone or visual indicator as to what type of metals the object is most likely made of.

Some metal detectors allow you to filter out (discriminate) objects above a certain phase-shift level. This helps greatly when trying to avoid or hunt for certain types of metals. You can usually set the level of phase shift that is filtered by simply adjusting a knob. Another discrimination feature of VLF detectors is called notching. A notch is a discrimination filter for a certain segment of phase shift. The detector will alert you to objects above this segment as well as objects below it.

Advanced detectors even allow you to program multiple notches. For example, you could set the detector to disregard objects that have a phase shift comparable to a soda-can tab or a small nail. The disadvantage of discrimination and notching is that many valuable items might be filtered out because their phase shift is similar to that of “junk.” But, if you know that you are looking for a certain type of object, these features can be extremely useful.

Cheap Metal Detectors Buying Ways for You

Buying a cheap metal detector can be the start of a new hobby and can provide hours of fun. However, metal detectors can be expensive to purchase but there are options for getting a deal.


cheap metal detectors

Discount tool and other retailers often sell inexpensive metal detectors. These detectors are generally very basic models without the more advanced discrimination tools of more expensive models. However, for looking for coins and jewelry on or near the surface of the ground these inexpensive models will work.
Used Metal Detectors

Buying a used metal detector is one way of getting a quality metal detector at a cheap price. Used metal detectors can be found at some hobby shops, metal detecting / treasure hunting shows, pawn shops, flea markets and online.
Internet Retailers and Auctions

Internet retailers and auction sites are a productive location for finding a explosive detection without spending a lot of time searching. Discontinued models from well known manufacturers, barely used metal detectors, and other inexpensive metal detectors can be found listed for sale on various websites.

How to Pass Chekpoint Smoothly and Safely

Be prepared. Before you get to the airport, take the necessary precautions to make your experience as simple as possible.

Wear practical shoes. Slip-on shoes will be easier to remove quickly. Of course, make sure they are comfortable enough for standing in long security lines.

Avoid metallic clothing or accessories, as you will have to remove these before going through a metal detector. The same goes for metal items in your pockets.
Package liquids and gels appropriately. All liquids in your carry-on bag must be in bottles of three ounces or less, and all these bottles must then be placed in a clear, quart-size, zip-style plastic bag. There are a few exceptions to this rule, including milk for infants and liquid medications, but be sure to check before you pack anything.

Pack your belongings in an organized way, so that if there is a problem, they can open your bag, check things out and move on.

Avoid contraband. Check beforehand to make sure that anything you will bring along, whether in your checked luggage or your carry-on, is allowed on the plane. Otherwise, you may be forced to throw away these items or even face questioning or prosecution.
