UGREEN’s FineTrack Slim Duo 2 is a card-style tracker made for wallets, passport holders, bags, and other everyday essentials. The biggest highlight here is that it works with both Apple Find My and Google Find Hub, so you aren’t locked into one ecosystem if you switch between iPhone and Android. It measures just 1.9mm thick, letting it slide into a wallet without adding much bulk, and there’s a built-in 110dB speaker to help you track it down when it’s nearby. UGREEN also adds left-behind alerts and Lost Mode, allowing other devices on Apple’s or Google’s finding networks to help locate it when it’s farther away. Another nice touch is RFID protection, along with a built-in battery that UGREEN says can last for several years.

Anker’s new SmartTrack Find My wallet card is another solid alternative to consider, currently down to $25 from its usual $35 price. It also works with both iOS and Android, making it another versatile option if you want a slim tracker for your wallet.

UGREEN FineTrack Slim Duo2 Wallet Tracker Card features:

One Wallet Tracker for Two Ecosystems: Easily pair the smart tracker with either Apple Find My or Google Find Hub for seamless item tracking across iOS and Android devices. Whether you’re using an iPhone or an Android phone, enjoy reliable global locating without monthly subscription fees. (Note: Supports either Apple or Android at one time, not both simultaneously.)
