Should I buy the Eufy SmartTrack Card or Apple AirTag for wallets?

For most standard wallets, the Eufy SmartTrack Card is usually the better pick because it’s thinner than an AirTag and fits a card slot more naturally, so it’s less likely to create a bulge. It also works with Apple’s Find My network, so you still get crowd-sourced location tracking through Apple devices.

Choose the Apple AirTag instead if you want Precision Finding on supported iPhones or prefer a tracker with a replaceable battery. The Eufy card is more wallet-friendly in shape, but it’s best if you’re using an iPhone-based setup, since it does not support Android.

Bottom line: Eufy SmartTrack Card for slim everyday wallet use; AirTag if you want the extra finding features or a replaceable battery. Exact finding behavior and compatibility can vary by device and app version, so check the current product pages if those details matter to you.
