Credit cards are an essential item to carry when travelling, but going through airport security can be a nerve-wracking experience. Many travellers worry about the potential for their credit cards to be damaged or demagnetised during security screening. While X-ray machines are generally considered safe for credit cards, metal detectors and hand wands may pose a risk of demagnetisation. Metal credit cards, in particular, could cause issues at airport security if they set off metal detectors. To ensure a smooth journey through airport security, it is recommended that travellers take precautions such as keeping their credit cards in a secure zippered pocket or bag, and considering the use of plastic sleeves to protect their cards from potential damage or demagnetisation.

What You'll Learn
Metal credit cards may set off airport security
Metal credit cards are usually made of titanium or other metals and are heavier and thicker than plastic cards. They are more expensive to manufacture and are often seen as a status symbol. While they may add a touch of luxury to your wallet, they could cause some issues when passing through airport security.
Some people have reported that their metal credit cards have set off the metal detectors at airport security, resulting in additional screening or delays. In some cases, the cards may even be confiscated if they are mistaken for prohibited items. Therefore, it is generally recommended to leave your metal credit card at home when travelling and to use a plastic card instead.
Additionally, it is worth noting that credit cards with magnetic strips can be demagnetized by certain types of hand wands used at airport security. This can cause problems with the magnetic strip on your card, rendering it unreadable by card readers. To avoid this, keep your credit cards in a plastic sleeve or away from metal objects that could create a short circuit, such as loose batteries or coins.
Overall, while metal credit cards can be a convenient and prestigious way to make purchases, they may cause some issues when passing through airport security. To avoid potential delays or problems, it is recommended to use a plastic card when travelling and to keep your credit cards away from metal detectors and hand wands. By taking these precautions, you can ensure a smoother journey through airport security and maintain the functionality of your credit cards.

X-ray machines will not demagnetize cards
X-ray machines used at airport security will not demagnetize cards. X-rays are a different type of energy than magnetism, and therefore cannot demagnetize cards. However, hand scanners and metal detectors have been known to have a strong enough magnetic field to affect cards, especially if you get too close to the wand or frame of the scanner.
To be safe, it is recommended to put your wallet in a shoulder bag and send it through the X-ray machine, while keeping a close eye on it. It is also a good idea to keep your most important credit card in a plastic sleeve, as body heat and moisture can affect the substrate of the magnetic stripe on your card and cause it to break down.
Additionally, it is important to avoid anti-security devices, as these are powerful electromagnets designed to demagnetize embedded anti-theft sensors. Card readers can also sometimes contribute to the problem of demagnetization.
While X-ray machines at airport security are not a cause for concern, it is worth noting that other sources of magnetism can potentially demagnetize your cards. For example, loose batteries in your pocket can demagnetize a credit card if they are connected to something metallic, such as coins or other batteries. Fridge magnets, magnetic zippers or buttons on clothing, and even card readers have been known to demagnetize cards.
To protect your cards, it is recommended to avoid placing them near any magnetic devices, such as refrigerators or televisions, and to keep them separate in your wallet, so that no two magnetic stripes are facing each other.

Hand scanners and metal detectors can demagnetize cards
While X-ray machines are generally considered safe for credit cards, there are some concerns about hand scanners and metal detectors. In theory, these devices do not have a strong enough magnetic field to affect cards. However, it is possible that if you hold your card close enough to the wand or frame of the scanner, it could potentially be demagnetized.
To avoid any potential issues, some people choose to place their wallets in their bags and send them through the X-ray machine instead. This can also make the security process smoother, as you won't have any metal objects on your person when passing through the magnetometer and wand. Additionally, keeping your most valuable credit card in a plastic sleeve can provide extra protection.
It is worth noting that other factors can also contribute to card demagnetization. For example, body heat and moisture can affect the magnetic stripe on your card, causing it to break down over time. Card readers themselves can also be a factor, depending on the quality and type of heads used. Some card issuers may also use cheaper materials that are more prone to wear and tear.
To minimize the risk of card demagnetization, it is recommended to keep your cards away from metal objects, magnets, and other cards with magnetic strips. Scratches on the magnetic stripe can also render a card unreadable, so it is best to store your cards in a soft, cushioned place to protect them from damage.
Overall, while hand scanners and metal detectors may have the potential to demagnetize credit cards under certain circumstances, there are multiple factors to consider when it comes to card demagnetization. Taking precautions and being mindful of your card's environment can help reduce the chances of encountering issues.

Keep your credit card in a secure zippered pocket
While X-ray machines at airport security will not demagnetize your credit cards, it is possible that certain types of hand wands used at security will. Therefore, it is advisable to keep your credit card in a secure zippered pocket when going through airport security. This could be a zippered shirt or blouse pocket, or a secure zippered pocket in a purse, "man bag", or personal bag. This way, you can keep your valuables on your person at all times and avoid the risk of demagnetization or theft.
If you have a metal credit card, it is especially important to keep it in a secure zippered pocket when going through airport security, as these cards may set off metal detectors. By keeping your metal credit card in a secure zippered pocket, you can avoid potential delays or issues at security checkpoints.
Additionally, keeping your credit card in a secure zippered pocket can help protect against moisture from perspiration, which can affect the magnetic stripe on your card and cause it to break down over time. It is also a good idea to keep your credit card separate from other metal objects, such as coins or batteries, to prevent the risk of a short circuit.
When going through airport security, you may be asked to remove your jacket or bulky clothing for screening. By keeping your credit card in a secure zippered pocket, you can easily access it and ensure that it remains with you at all times, even if you need to remove your outer layers for inspection. This can provide peace of mind and help streamline the security process.
Overall, keeping your credit card in a secure zippered pocket when traveling through airport security is a practical and prudent measure. It can help protect your card from potential demagnetization, moisture damage, and theft, while also facilitating a smoother and less stressful security screening process.

Card readers can contribute to card demagnetization
Credit cards can go through airport security without being damaged. X-ray machines and metal detectors do not have a strong enough magnetic field to affect cards. However, hand scanners and metal detectors could potentially affect cards if held close enough. Anti-security devices are also best avoided, as they are powerful electromagnets that can demagnetize cards.
Additionally, card readers can sometimes struggle to read certain cards due to the quality of the card. Some card issuers use cheaper magnetic strips that wear down more quickly. This can result in the need to replace the card frequently.
It is worth noting that while card readers can contribute to card demagnetization, there are other factors to consider as well. For example, storing cards in direct contact with metal clasps or keeping them in the same pocket as keys or other metal objects can also lead to demagnetization. Scratches on the magnetic strip can also render the data unreadable.
To prevent card demagnetization, it is recommended to keep cards away from metal objects and magnets, and to store them in a soft, cushioned place. If a card does become demagnetized, it can be replaced by contacting the card company.
