What You'll Learn
Metal credit cards and airport security
Metal credit cards are elite credit cards that have been released by several major issuers in recent years. These cards are made of metal, with some even being made of palladium and 24-karat gold. While these cards are designed to impress, they can cause issues when going through airport security.
Metal credit cards will set off airport metal detectors. Mike England, a spokesman for the Transportation Security Administration (TSA), confirmed that "anything made of metal will set off the metal detectors". This means that if you have a metal credit card in your wallet, you will likely be pulled aside by the TSA to figure out what triggered the metal detector.
To avoid this inconvenience, it is recommended to place metal credit cards in the plastic tray that goes through the conveyor belt, along with your cellphone and keys. This way, TSA officials can quickly determine that the metal object detected is a credit card and not a small knife or something else that could be used as a weapon.
Additionally, it is important to note that while X-ray machines used in airport security will not demagnetize credit cards, hand scanners and metal detectors could potentially have a strong enough magnetic field to affect the cards if you get too close. Therefore, it is generally recommended to keep your credit cards in a plastic sleeve when going through airport security.
Overall, while metal credit cards may cause a slight delay when passing through airport security, it is not a significant issue and can even make for a good story. It is essential to be aware of the potential for metal cards to set off metal detectors and to take the necessary precautions, such as placing them in the provided plastic trays.

X-ray machines and credit cards
When travelling by air, passengers and their carry-on luggage are examined using X-ray machines and body scanners to identify prohibited items. This process is essential for ensuring the safety and security of the airport and aircraft.
Some passengers are concerned that X-ray machines may damage their credit cards. The primary concern is the demagnetisation of the magnetic stripe on the credit card. X-ray machines, however, are a different type of energy than magnetism and will not demagnetise cards. They are similar to visible light but with a higher frequency and power level.
Metal detectors, on the other hand, can damage credit cards. The magnetic field is usually not strong enough to affect cards, but if you get too close to the wand or frame of the scanner, demagnetisation could occur. Credit cards made of metal can also set off airport metal detectors, though the amount of metal is usually too small to cause any problems.
To prevent potential damage, there are several precautions you can take. Keep your most important credit card in a plastic sleeve, and avoid anti-security devices, which are powerful electromagnets that can demagnetise cards. It is also a good idea to keep your wallet and valuables in a locked carry-on bag that will go through the X-ray machine, rather than in your pockets or by hand.

Criminals and credit card fraud
While airport screening machines can damage credit cards, the risk is minimal compared to the threat of credit card fraud by criminals. Credit card fraud is a pervasive issue, with 15.2% of theft, property destruction, and fraud cases in the US in 2023 involving credit card and other financial instrument fraud. This multifaceted crime encompasses various techniques, such as pickpocketing, data breaches, and sophisticated cyber scams.
One prevalent method employed by criminals is skimming, where devices are used to steal credit card information from unsuspecting victims. This can occur at various locations, including stores and airports, where anti-security devices can inadvertently demagnetize cards. Criminals also exploit data breaches and the "Dark Web" to obtain and sell personal information. Additionally, application fraud involves using stolen or fake documents to open accounts in someone else's name, enabling fraudsters to maximize credit card spending or turn purchases into cash.
Cybercriminals are becoming increasingly sophisticated in their tactics, often impersonating senior staff members to deceive employees into transferring money to fraudulent accounts. They also target victims' social security numbers and passwords, locking legitimate users out of their accounts. Credit card fraud is a federal crime in the US when it "affects interstate or foreign commerce," and cardholders are generally liable for only $50 in theft cases if reported within 60 days.
To protect yourself from credit card fraud, consider implementing safety practices such as learning to identify phishing and skimming attempts. You can also use an "autopay and every day" credit card strategy, where you designate one card for autopay accounts and another for everyday purchases. Freezing your credit reports is another proactive measure to prevent criminals from opening new accounts in your name. Additionally, always contact your credit card issuer, the police, and major credit bureaus immediately if you suspect any fraudulent activity.
In summary, while airport screening machines may pose a minor threat to the functionality of your credit cards, the greater concern lies in protecting your financial information from criminals who employ a wide range of tactics to commit credit card fraud. Vigilance and proactive safety measures are crucial to reducing your exposure and limiting potential damage.

RFID wallets and airport security
Credit cards, passports, and driver's licenses now come with embedded radio frequency identification (RFID) chips. When activated by an RFID reader, these chips wirelessly transmit certain types of information, allowing users to verify their identity or make purchases without swiping their cards. However, this technology has raised concerns about the potential for RFID-enabled cards to be scanned or cloned by criminals.
To address these concerns, RFID-blocking wallets have been introduced to the market. These wallets are designed to prevent RFID signals from being transmitted or received, thereby protecting personal information from unauthorized access. While some travelers opt for these wallets to safeguard their data, others worry about potential issues during airport security checks.
RFID-blocking wallets are not known to cause significant problems during airport security scans. X-ray machines, metal detectors, and millimeter-wave scans are not affected by these wallets, as long as they are placed in the X-ray machine bins for scanning. The wallets are essentially simple foil or mesh Faraday cages, which X-ray machines can easily penetrate.
However, it is important to remove passports or IDs from their RFID-blocking covers or wallets when presenting them to border control agents. These agents use NFC readers designed for near-range scanning, and covering the documents can hinder the scanning process. Additionally, keeping the wallet on your body during security checks may trigger the millimeter-wave scanner, resulting in you being pulled aside for further inspection.
In conclusion, while RFID-blocking wallets can enhance the security of your personal information, it is advisable to remove RFID-protected documents from their covers during border control checks and to ensure that the wallet is placed in the X-ray machine bins for scanning to avoid any potential issues during airport security procedures.

Card quality and airport screening
Airport screening is a stressful process, and the last thing travellers need is for their credit cards to be damaged by the screening machines. The good news is that, for the most part, airport screening machines will not damage credit cards. However, there are certain precautions that should be taken, especially with regard to metal detectors and anti-security devices.
Metal credit cards, which have become increasingly popular due to their heft and "plunk factor", can set off airport metal detectors. While metal detectors typically do not have a strong enough magnetic field to affect cards, it is possible for them to damage credit cards if the cards come into close contact with the wand or frame of the scanner. Additionally, anti-security devices, which are designed to de-magnetize anti-theft sensors, can also potentially damage credit cards.
To protect credit cards from potential damage, it is recommended to keep them in a plastic sleeve and avoid placing them near anti-security devices. It is also a good idea to keep cards in a locked carry-on bag that will go through the regular X-ray screening, as X-ray machines will not de-magnetize cards.
The quality of credit cards can also play a role in their susceptibility to damage. Some card issuers may use inexpensive blanks, which can result in faster wear and tear. Cards with magnetic strips may also be more prone to damage over time, especially with frequent use.
Overall, while airport screening machines typically do not damage credit cards, taking simple precautions can help ensure the functionality and longevity of credit cards during the travel process.
