As you consider using AirTags to keep track of your belongings, you might be wondering if they pose a risk to the cards in your wallet. It’s important to understand if AirTags can potentially demagnetize credit cards, especially those that still use magnetic strips.

While most payment cards now use chips, there are still several cards relying on magnetic stripes.

In this article, we will explore the likelihood of AirTags causing harm to these types of cards, putting your mind at ease as you make use of this convenient tracking tool.

LONDON, UK – January 2021: Apple air tag device that helps people keep track of personal items.

Do Airtags Demagnetize Credit Cards

Chip and Magnet Interference

AirTags do not possess any magnetic properties that could damage the magnetic strip on your credit cards. In fact, most modern cards use a chip rather than a magnetic strip, reducing the need to worry about demagnetization.

NFC and Airtags

AirTags make use of Bluetooth technology rather than NFC (near-field communication) to connect with your compatible devices. As a result, your credit cards, which may use NFC for contactless payments, will not experience any interference from AirTags. Furthermore, AirTags and NFC-enabled cards employ different methods for transmitting information, ensuring that their signals will not interfere with one another.

In conclusion, it’s safe to carry your AirTags and credit cards together without fear of demagnetization or interference. While care should be taken with any electronic device, AirTags pose no direct risk to your credit cards.

Airtags and Wallet Compatibility

Sound and Alert Features

AirTags are designed to help you locate your items using the Find My app. They emit a sound and alert to notify you of their location. The sound feature is especially useful when you misplace your wallet, as it can guide you to its hiding spot.

Replacing an AirTag’s battery is simple and cost-effective, as they use a standard CR2032 battery. This ensures that your AirTag remains functional for long periods, and you can easily replace it when needed.

Using Airtags for Wallets

Although AirTags use ultra-wideband technology, they won’t demagnetize your credit cards. Your cards and the AirTag operate on different radio frequencies, ensuring they won’t interfere with one another. You can confidently place an AirTag in your wallet without worrying about damaging your cards.

AirTags, when placed in a wallet, still allow the Find My app to locate them effectively. Wallets typically don’t block the signal from the AirTag, so you can always rely on locating your wallet using Apple’s AirTag technology.

To make it easier to integrate an AirTag into your wallet, consider using AirTag-specific wallet accessories, such as Nomad’s Card for AirTag. This way, you have a secure and designated spot for your AirTag, ensuring that it stays put and doesn’t get lost within your wallet’s compartments.

In Summary:

  • AirTags work well in wallets without damaging your cards.
  • The Find My app function remains effective when AirTags are placed in a wallet.
  • Consider using AirTag-friendly wallet accessories for added security and convenience.

Airtag Technology

Ultra-Wideband Technology

AirTags use ultra-wideband (UWB) technology, providing highly accurate tracking capabilities. This allows your iPhone to determine distance and direction to your missing items.


To set up your AirTag, simply bring it close to an iPhone running iOS 14.5 or later. Your iPhone will recognize the NFC-enabled AirTag and guide you through the process.

iPhone Compatibility

For the best tracking experience, use an iPhone with a U1 Ultra Wideband chip. Compatible devices include iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max.

Lost Mode and Notifications

Custom Messages and Apple ID

When you enable Lost Mode on your AirTag, you can set a custom message with your phone number or email address. This helps others contact you if they find your lost item. Your Apple ID is associated with the AirTag, meaning you maintain control over this personal information.

Cross-Device Notifications

Upon activating Lost Mode, your AirTag will notify you when it is detected by another device in the Find My network. This allows you to track your lost items across a wide range of Apple devices. Make sure your Apple ID is connected to all your devices to ensure seamless notifications.

In addition to Apple devices, AirTags can also be detected by Android devices through NFC. This broadens the potential finders for your lost items and enhances your chances of recovering your belongings. Remember, keeping your notification settings up-to-date can assist you in effectively tracking your AirTag.

Airtags Vs. Other Item Trackers

Tile and Other Options

When considering AirTags, you should also look at Tile, a popular item tracker with various models available. Tile trackers connect via Bluetooth and offer features like last-seen location and community search support.

Another option is Chipolo, which is similar to Tile and AirTags. Chipolo offers a couple of models, each with different features like water resistance.

Android Phone Compatibility

AirTags are designed for Apple users, leveraging the vast network of iPhones, iPads, and Macs for seamless tracking. However, they may show limited functionality with Android phones.

For Android users, Tile and Chipolo provide better compatibility. Both brands offer Android apps that enable tracking and various other helpful features.

Remember to choose an item tracker that suits your needs and is compatible with your devices. These trackers will help protect your belongings while also providing you with peace of mind.

Additional Features and Considerations

Battery Type and Replacement

AirTags use a CR2032 battery, which is easy to find and replace. This battery typically lasts for about a year, so you don’t have to worry about frequent replacements.

Disabling and Security

AirTags come with security features to prevent unwanted tracking. If you find an unknown AirTag attached to your belongings, you can disable it using your iPhone.

Ultra-wideband Chip

The ultra-wideband chip in AirTags allows for precise location tracking. This means you’ll have a much easier time finding your misplaced items, such as keys, luggage, and purses.

Magnets and Credit Cards

Concerns may arise about AirTags and their potential to demagnetize credit card strips. If you plan to keep an AirTag near your credit cards, consider that most payment cards now use chip technology, reducing the risk of demagnetization.

Remember, to keep your credit cards’ magnetic strips in good condition, occasionally clean them with a soft cloth and ensure they’re not exposed to strong magnetic fields.
