UGREEN FineTrack Slim S (Samsung Only) Wallet Tracker Card, 1-Year Rechargeable Bluetooth Tracker Card Finder Work with Samsung SmartThings APP for Galaxy S25/S24/S23 Ultra -1.7mm & IP68 Waterproof

The UGREEN FineTrack Slim Wallet Tracker Card is a credit‑card‑thin Bluetooth tracker designed to help you keep track of your essential items — wallets, passports, luggage, or bags — without bulk. Thanks to its slim 1.7 mm profile, it can slip into a wallet or card slot and remain nearly invisible. Depending on the variant, it integrates either with the Apple Find My network (for iOS) or with the Samsung SmartThings (for some Android devices like Samsung). The tracker uses a rechargeable battery (magnetically charged) and offers features like a loud alert buzzer and waterproof protection, making it a practical option for travel and daily carry.

Key Features

Samsung Find APP Certified: UGREEN FineTrack Slim S is certified by Samsung Find APP and connects directly through the official app—no third-party apps needed. Designed exclusively for the Samsung system (not compatible with other Android or iOS systems), perfect for Samsung users who value native system integration and simplicity.
Ultra-Thin Yet Durable — Only 1.7mm thick, made with advanced cold-pressing technology. Corresponds to the thickness of 1 coin but is thinner and stronger than a standard card tracker, making it not easy to bend or break. You can easily put it in your wallet without getting stuck
Rechargeable & Long-Lasting: Magnetic charging in 2 hour powers up to 1 years. No need to replace batteries like single-use wallet trackers, easily check the battery level through the app. (TIP: The red light will stay on and turn off after fully charged. The tracker is fully charged when it comes, so it may flash a red light and go off when charging at this time)
Find the Phone with a Ring: Can’t find your Galaxy phone nearby? Simply double-press the button on your Smart Tag, and your phone will ring instantly—perfect for finding your phone hidden in the sofa, a backpack, or anywhere close by.
Global Tracking & Loud Sound: For long-range tracking, the wallet card tracker leverages the global Samsung network to locate your items anywhere. It features a built-in buzzer that plays a loud sound for easy close-range locating. Additionally, the phone will promptly notify you if you leave the tagged item behind. (Alert distance adjusted based on the environment.)

Customer Reviews

5.0 out of 5 stars Thin. Great for some use cases!

For a bluetooth tracker, it's pretty good. Nice and slim. Slips into wallet easily. Much more user friendly than Smart tags 2 in some use cases where slim or secrecy are needed. I was surprised how easy it was to charge the card with the enclosed cable. c
