The DERETE Smart Slim Wallet Tracker Card is a credit-card-shaped Bluetooth tracker that works only with Apple's Find My network. It is built to slide into a wallet, passport holder or luggage tag and be found through the Find My app or Siri. It recharges wirelessly and is rated IP68 for water and dust. Against rivals like the Apple AirTag, it wins on thickness and wallet fit but loses on Android support and on the precision finding that ultra-wideband AirTags offer. Its 3.5-out-of-5 rating from 19 buyers suggests a mixed reception.

Buyers like the slim card format and the wireless charging, and several say it disappears into a wallet without adding bulk. Complaints center on the Apple-only limitation and on locating items by sound, which some find too faint to follow.
This is a slim tracker card that fits in a wallet. It can also be attached to an ID card, luggage tag, passport or electronic device. It works with Apple's Find My network and does not support Android devices.
The card charges wirelessly, and a full charge lasts up to 5 months. A color-changing LED light shows the charge status. Within Bluetooth range of up to 164 feet, you can make the built-in speaker sound from your phone or by asking Siri. Out of range, your iPhone gets a notification with the card's last known location, which you can also view in the Find My app. There are no subscription fees.
Lost Mode uses the Find My network of Apple devices and sends a notification when an Apple device detects the card. With iOS 17, the card can be shared with up to 5 borrowers, who can see its location on a map. They do not get tracking notifications when it moves with them. Location data is anonymous and encrypted, and the card does not store your location data or history publicly. It has an IP68 rating and withstands immersion in water up to 3 feet for 30 minutes.
