Airport security systems use various methods to ensure the safety of passengers, including metal detectors, backscatter x-ray machines, millimeter wave scanners, and cabinet x-ray machines. While it is not common for airports to use x-ray scanners on people, they are often used to scan carry-on items and checked luggage. In terms of wallets, some travelers have reported being asked to remove them for additional screening, either via X-ray or hand search. However, others have reported being able to keep their wallets in their pockets or carry-on bags without issue. Ultimately, it appears that the policies and procedures regarding wallet screening may vary across different airports and security protocols.

TSA demands for wallet surrender for X-ray screening
While there are no explicit TSA demands for wallet surrender for X-ray screening, travellers have reported being asked to remove their wallets for screening at US airports. This may be due to the amount of metal in wallets, which can set off the alarm. In addition, some travellers have reported that their wallets were detected by X-ray machines, while others have suggested that the new infra-red thermal conductivity scanners can detect changes in temperature from clothing to objects carried under clothing, which could include a wallet.
To ensure a smooth screening process, it is recommended that travellers remove all items, including wallets, from their pockets and place them in a carry-on bag or on the X-ray belt for screening. Some travellers have reported that they keep their wallets in their carry-on bags to avoid this issue, while others have suggested that walking through the X-ray machine with their wallet in their pocket has not caused any issues. It is important to listen to the instructions of the TSA officers, as they may instruct travellers to separate certain items from their carry-on bags to obtain clear images on the X-ray machine.
It is worth noting that TSA PreCheck® allows travellers to speed through security without removing shoes, laptops, liquids, belts, and light jackets. However, this does not include wallets, as they may contain metallic or non-metallic threats, including weapons and explosives. In most cases, travellers will have the opportunity to decline Advanced Imaging Technology (AIT) screening, which uses millimetre wave technology, in favour of physical screening. However, some travellers may be required to undergo AIT screening if selected for enhanced screening prior to their arrival at the security checkpoint.
While the majority of travellers will not be affected by this requirement, it is important to follow the instructions of TSA officers to ensure a safe and efficient screening process. In the case of wallet screening, travellers can place their wallets in a plastic bin or tray provided for this purpose, and they should never be left unattended to prevent theft. Overall, it is advisable to cooperate with TSA demands, even if they may seem unnecessary, to ensure a smooth and efficient travel experience.

X-ray machines can see through RFID wallets
RFID wallets are usually made of carbon fibre, aluminium, or other metals, which are effective at blocking radio waves. However, X-ray machines can easily penetrate these materials. X-ray machines are used to identify objects that may be hidden by passengers and to create images of what is in their luggage. They are also used to detect threats such as weapons or explosives that a person could be carrying under their clothing.
When going through airport security, it is recommended to put your wallet in the bin for X-ray scanning. If you keep it on your body, you may be pulled aside for additional screening, which may include a physical examination. This is because full-body scanners may detect your wallet as an anomalous object, especially if it is made of metal.
While RFID wallets can provide some peace of mind when it comes to protecting your personal information, they do not offer any advantages when it comes to airport security. It is important to follow the instructions of TSA agents and remove your wallet for screening if requested.

Full-body scanners used in the EU are millimeter-wave scanners
Full-body scanners used for security in airports and other contexts employ millimeter-wave technology to detect objects concealed underneath clothing. Millimeter-wave scanners use non-ionizing electromagnetic radiation in the extremely high frequency (EHF) radio band, which is a lower frequency than visible light. This technology is distinct from backscatter X-ray scanners, which use ionizing radiation to detect objects and are considered more invasive.
The first millimeter-wave full-body scanner was developed at the Pacific Northwest National Laboratory (PNNL) in Richland, Washington, in the 1990s. This technology was later commercialized by SafeView, Inc., a Silicon Valley startup that obtained an exclusive license to PNNL's intellectual property. From 2002 to 2006, SafeView developed a production-ready millimeter body scanner system, along with software that included scanner control, threat detection algorithms, and object recognition capabilities.
Millimeter-wave scanners create a 3D, black-and-white, whole-body silhouette of the subject, utilizing automated target recognition (ATR) software to detect and highlight potential threats. This technology can identify liquids, gels, plastics, powders, metals, ceramics, explosives, drugs, and money. The use of ATR software helps address privacy concerns by producing a generic outline of a person, rather than revealing their unique physical features.
Full-body millimeter-wave scanners have been implemented in airports across the United States and Europe. Schiphol in the Netherlands was the first airport to adopt SafeView's millimeter-wave body scanner on a large scale. The European Union currently allows member states to decide whether to implement full-body scanners in their national airports, with the provision that they adhere to EU-wide standards on detection capability and comply with health and fundamental rights provisions.
While millimeter-wave scanners are widely used, there have been concerns about their efficacy in detecting threatening objects. Some studies suggest that these scanners struggle to detect objects, including weapons, and have a high false-positive rate. Additionally, there are ongoing debates about the health risks posed by millimeter-wave scanners, although they are generally considered safer than backscatter X-ray scanners due to their lower radiation output.

Metal detectors may detect RFID wallets as metallic objects
Metal detectors at airports are used to identify prohibited items, including dangerous objects, certain chemicals, and liquids above specific volumes. During this process, passengers are usually required to remove outerwear, shoes, and belts and empty their pockets.
RFID wallets have become popular due to their ability to protect sensitive information. However, they contain metal components, which may set off alarms during airport security scans. The amount of metal in RFID wallets is typically minimal and may not be enough to trigger a metal detector. Still, it is essential to be aware of airport security procedures and guidelines.
In the event that an RFID wallet does activate a metal detector, it is a standard procedure for airport security. The wallet would simply be placed in a separate bin and sent through the X-ray machine for further inspection. This process will not damage or affect the RFID-blocking feature of the wallet, ensuring that personal data remains secure.
Some travellers have reported that their wallets were subjected to additional screening, either via X-ray or hand search, at certain airports. It is recommended to familiarise yourself with the security protocols at the airports you will be visiting, as well as any specific guidelines regarding RFID wallets, to ensure a smooth journey.

X-ray scanners for people are not used in the US or EU
It is important to note that the use of X-ray body scanners in airports has been controversial. In 2011, Europe banned the use of X-ray body scanners that were being used in US airports due to concerns about the potential health risks associated with the technology. It was estimated that scanning hundreds of millions of passengers per year with this technology could result in a small number of cancer cases.
Instead of X-ray scanners, some airports in the US and EU have started using alternative technologies, such as metal detectors, millimetre-wave scanners, and infrared thermal conductivity scanners. These scanners can detect metal objects and changes in temperature without using ionizing radiation that could pose a health risk.
While X-ray scanners for people may not be used in the US or EU, X-ray scanners for baggage are still commonly used in airports around the world. These scanners help detect prohibited items and ensure the safety of passengers and staff. Additionally, X-ray scanners are used in other security settings, such as prisons and detention centres, to detect contraband and enhance security.
In conclusion, while there may be variations in security procedures across different airports, it is generally not necessary to remove wallets from pockets or bags when passing through security in the US or EU. The use of X-ray scanners for people is not common in these regions due to health and safety concerns, and alternative screening technologies are typically used instead.
