The Essentialbag Tracker Karte Pro is a credit-card-shaped Bluetooth tracker that fits in a wallet card slot and works with Apple's Find My and Google's Find Hub networks. Its main draw is battery life: the current version runs about 10 months per charge instead of 4. It is for anyone who keeps losing a wallet, purse or travel pouch and already uses an iPhone or Android phone. Against coin-sized trackers like AirTag or Tile, it is thinner and wallet-friendly but has no speaker for a loud ring and no ultra-wideband precision finding.

Rated 4.9 out of 5 from 587 ratings, buyers mostly praise the slim card fit and the long battery life. Complaints are few and center on the lack of a loud ring and the need to recharge.
The Tracker Karte Pro is a tracker card that helps you find your Smart Wallet. It works with Apple's "Wo ist?" (Find My) app and Google's Find Hub, and it appears in the built-in map apps on iOS and Android devices. It locates the wallet worldwide through the app, with no additional costs.
The card has a built-in speaker with a loud alert tone, so you can find the wallet nearby, even among cushions, bags or jackets. This newest version runs for 10 months per charge, up from 4 months on the previous version.
The card is 1.9 mm thick, about as thin as a regular card. It is designed to fit the Smart Wallet 3.0 and works like an additional card in the wallet.
