Do Magnetic Wallets Damage Credit Cards? What to Know

Quick answer

No, a magnetic wallet will not damage or erase your credit cards. Modern credit cards use secure chips and encryption, not magnetic strips, so the magnets in MagSafe wallets pose no risk. Even older magnetic-strip cards are safe because the magnets used in wallets are not strong enough to demagnetize them.

The truth about magnets and credit cards

The fear that magnets erase credit cards comes from outdated technology. Early credit cards relied on magnetic strips, which could be demagnetized by strong magnets. Today, most cards use EMV chips, which are immune to magnetic fields. The magnetic strip on the back is a backup, and it would take a very powerful magnet—like an industrial electromagnet—to cause damage. Wallet magnets are designed to be strong enough to hold your phone but not strong enough to harm your cards.

How MagSafe wallets actually work

MagSafe wallets use small, carefully placed magnets to snap onto the back of your phone or a MagSafe-compatible case. These magnets are engineered for secure attachment, not for creating a strong magnetic field that could affect your cards. In fact, the cards sit in a pocket that is typically shielded or positioned away from the magnets. For example, the Card Wallet - Black from Mous uses an extremely secure magnetic attachment and features 100 silicone dots on the back for enhanced slip resistance, keeping your cards in place without exposing them to harmful magnetic forces.

What about hotel key cards and other magnetic items?

Hotel key cards and some access badges still use magnetic strips, and they are more vulnerable to demagnetization than credit cards. However, the magnets in a wallet are unlikely to erase them unless they are in direct, prolonged contact. To be safe, keep hotel keys in a separate pocket or away from the wallet's magnetic area. Your credit cards, however, are not at risk.

Tips to keep your cards safe and secure

Even though magnetic damage is not a concern, you should still protect your cards from physical damage and loss. Use a wallet that holds cards snugly to prevent them from falling out. Avoid placing your wallet near strong magnets, like those in large speakers or MRI machines. And regularly check that your cards are not bent or cracked, as physical damage can make them unreadable.

Myths vs. facts

• Myth: Magnets in wallets erase credit cards: Credit cards today use chip technology, which is not affected by magnets. Even magnetic strips require a much stronger magnetic field to be erased than what a wallet magnet produces. Verdict: False. Your cards are safe.
• Myth: You need to keep your cards away from your MagSafe wallet: MagSafe wallets are designed to hold cards securely without exposing them to harmful magnetic fields. The magnets are positioned to attach to your phone, not to interfere with your cards. Verdict: False. MagSafe wallets are safe for cards.
• Myth: Hotel key cards are safe in a magnetic wallet: Hotel key cards often use magnetic strips that can be demagnetized by close contact with strong magnets. While wallet magnets are not typically strong enough, it's best to keep hotel keys separate. Verdict: Partially true. Use caution with hotel keys.
