UGREEN FineTrack Slim S Wallet Tracker Card — Samsung-only 1.7mm, IP68, 1-Year Rechargeable

UGREEN FineTrack Slim S is an ultra-thin, rechargeable wallet tracker card built specifically to work natively with Samsung SmartThings for fast locating, audible alerts, and global network tracking.

This slim tracker card slips into a wallet, card sleeve or pocket without adding bulk while connecting directly to the Samsung Find network—no third-party apps required. Engineered for Samsung devices (compatible with Galaxy S25/S24/S23 Ultra and other Samsung models supported by SmartThings), the FineTrack Slim S balances a paper-thin profile with durable construction, IP68 water resistance, and a rechargeable battery that can last up to a year per charge.

How thin and durable is the card for everyday carry?

The FineTrack Slim S measures just 1.7mm, about the thickness of a single coin, yet it uses cold-pressing manufacturing to resist bending and breaking. Its rigid, flat form is designed to slide into card slots or slim compartments without sticking out or warping over time.

• Thickness: 1.7mm for minimal added bulk
• Construction: cold-pressed for strength and flexibility resistance
• Form factor: flat card fits standard wallet and sleeve spaces
• Durability: built to resist everyday bending and pocket wear

What battery and charging features does it offer?

This tracker uses a rechargeable cell with magnetic charging that reaches a full charge in about two hours and can run up to one year between charges under typical use. The app shows battery status so you know when to charge, and the card includes an LED indicator that signals charging progress.

• Recharge method: magnetic charger included for easy alignment
• Charge time: roughly 2 hours to full
• Runtime: up to 1 year on a full charge (usage-dependent)
• Battery visibility: charge level visible in the SmartThings app

How does locating and alerts work with Samsung devices?

FineTrack Slim S links directly into the Samsung Find network through the SmartThings app, enabling both nearby audible locating and long-range community-assisted location. Pressing the tracker can also trigger your Galaxy phone to ring, making it simple to find a misplaced phone or card close by.

• Native integration: certified for Samsung Find/SmartThings
• Nearby locating: built-in buzzer emits a loud sound for quick retrieval
• Phone find feature: double-press to ring your Galaxy device
• Global network: Samsung's crowd-sourced network helps locate distant items

Can I review past locations or rely on it in wet conditions?

The Smart Tag stores historical location data for up to seven days in the SmartThings app so you can check where an item has been recently. With IP68 water resistance, the tracker tolerates splashes and brief immersion, so it stands up to everyday exposure in pockets and bags.

• History: location trace logs retained for up to 7 days
• Water resistance: IP68 rating for splash and immersion protection
• Environmental alerts: phone notifications when a tagged item is left behind
• Reliability: built for real-world use in wallets, purses, and pockets

Who is this for? The UGREEN FineTrack Slim S is ideal for Samsung owners who want a low-profile, durable card tracker that works natively with SmartThings—perfect for people who carry slim wallets, frequently misplace phones or cards, or want rechargeable convenience without replacing single-use batteries. If you use a Samsung Galaxy device and prefer seamless system integration, this tracker offers a slim, weather-resistant solution for keeping everyday items locatable and secure.
