UGREEN FineTrack Slim S (Samsung Only) Wallet Tracker Card, 1-Year Rechargeable Bluetooth Tracker Card Finder
Quick take
UGREEN FineTrack Slim S is a credit-card-style wallet tracker designed for Samsung users, using Samsung SmartThings Find for setup and tracking. It aims to make “where is my wallet?” moments easier with a built-in buzzer for nearby searching, plus reminders when you leave the item behind and up to 7 days of stored location history. The biggest caveat is compatibility, it’s Samsung-only, so it will not be a fit for iPhone users or non-Samsung tracking setups.
Pros and cons
Pros
- Ultra-slim design at 1.7mm, made to sit comfortably in a wallet.
- Rechargeable battery with magnetic charging, up to about 1 year per charge.
- Works through Samsung SmartThings Find, with direct integration for Samsung devices.
- Includes a buzzer for finding the wallet nearby and supports left-behind notifications.
Cons
- Samsung-only compatibility, not for iOS or other Android ecosystems.
- Some buyers mention the app connection and location display can be slower or show loading for nearby use.
- Sound is intended to be useful, but because it’s inside a wallet, it may be harder to hear in louder environments.
What buyers think
Buyer feedback centers on two themes: the thin, wallet-friendly form factor and the convenience of Samsung SmartThings Find setup. Multiple reviews highlight that the tracker is discreet in a wallet and helps with locating a misplaced wallet using on-demand sound. Users also frequently mention the rechargeable approach as a practical upgrade over disposable battery trackers. On the downside, buyer-review evidence is limited but there are recurring mentions of occasional connectivity delays or the app showing a loading state when attempting to see the location nearby, and a note that the buzzer can be difficult to hear if you are not in a quiet area or if the wallet is inside a pocket.
What this tracker is, and who it’s for
The UGREEN FineTrack Slim S is an item finder card built to slip into your wallet, letting you monitor and locate your belongings from your Samsung phone. It’s meant for people who want a low-profile tracker that does not add obvious bulk to everyday carry. It also fits shoppers who prefer staying within the Samsung ecosystem, since it uses SmartThings Find rather than requiring a separate app to manage the tracker.
Key features that matter day to day
Samsung smartthings find integration
Setup and everyday tracking are designed around Samsung’s Find experience. The practical benefit is fewer steps and less switching, since the tracker is intended to connect directly through Samsung’s system on compatible Galaxy phones.
Nearby finding with a buzzer
When the wallet is close by, you can use the tracker’s sound feature to help you locate it faster around your home, car, or nearby areas. This is especially useful for common “left it somewhere in the room” scenarios.
Phone notifications if you leave the item behind
The tracker can help you stay aware if you move away from your wallet. The alert distance can vary based on the environment, so your results may differ depending on obstacles and signal conditions.
Rechargeable battery, no frequent replacements
Instead of disposable batteries, FineTrack Slim S uses magnetic charging. UGREEN states magnetic charging takes about 2 hours for a charge, and the battery can last up to around 1 year. Buyers who dislike changing batteries tend to like this style of rechargeable tracker.
IP68 water resistance
With an IP68 rating, this tracker is designed to better handle everyday exposure to water and dust. It is still a wallet accessory, so avoid intentionally submerging it or exposing it to things that could damage your wallet or phone.
Location history stored for up to 7 days
The app can store historical location data for up to 7 days. This can help you review where your wallet was before it went missing and improve the odds of retrieval.
Pros and cons in plain terms
Pros
- Very wallet-friendly: 1.7mm thickness is designed to reduce wallet bulk and discomfort.
- Simple Samsung setup: SmartThings Find integration is tailored for Samsung users.
- Rechargeable design: magnetic charging supports long-term use without replacing batteries.
- Usefully multi-mode tracking: buzzer for close range, notifications for left-behind situations, and location history.
Cons
- Compatibility is the deal-breaker: if you do not have a compatible Samsung setup, you’ll be better off choosing a tracker that supports your phone ecosystem.
- Nearby location visibility may vary: some buyers report moments where the app takes time to show location data.
- Sound depends on conditions: since it’s inside a wallet, hearing it may be easier in quieter environments.
Setup and compatibility checklist
Before buying, confirm you have a compatible Samsung phone and plan to use SmartThings Find. This tracker is intended for Samsung devices only, so it is not the right choice if your daily driver is an iPhone or if you want a cross-ecosystem tracker.
Also note that battery serviceability is rechargeable, which is convenient for long-term ownership. You’ll want to be okay with periodically charging the tracker with its magnetic charging method.
Is it worth it?
The UGREEN FineTrack Slim S is a strong choice for Samsung Galaxy owners who want a thin wallet tracker with rechargeable power and a SmartThings Find workflow. It’s particularly appealing if you frequently misplace your wallet in nearby places and want quicker “find it now” assistance through a buzzer, plus ongoing reminders and a short window of location history.
If you need a tracker for iOS or mixed-device households, or you want a one-size-fits-all setup that works across phone brands, you’ll likely prefer a different tracker category option built for your ecosystem.
