Find My Card Tracker, Wireless Charging Wallet Tag

The weakness of most tracking tags is the battery. A coin cell lasts a year, then the tag goes quiet, and you find out it went quiet at the exact moment you needed it. This one recharges wirelessly instead, so keeping it alive is a habit rather than a diary entry.

It is card shaped and card thin, which means it sits in a wallet slot behind your cards rather than adding a lump to a back pocket. It registers in the Apple Find My app alongside your other devices, so locating it uses the same interface you already know, and the Find My network relays its position through any nearby Apple device rather than needing you to be within Bluetooth range yourself.

Drop it into a wallet, a passport holder, a laptop sleeve or a bag lining. Set it on a wireless charging pad every few months and it stays live indefinitely. One important limitation: it works through the Apple Find My network and is for iOS devices only. It will not pair with an Android phone.
