eufy Securityeufy Security SmartTrack Card E30 (Black, 1-Pack), Rechargeable, Works with Apple Find My (iOS Only), Bluetooth Tracker, Perfect for Wallet, Passport, and Laptop, Water Resistant

I’m very happy with this tracker—it gives me real peace of mind knowing I won’t accidentally lose or forget my wallet. The device is about the size of a credit card and roughly as thick as two cards, which fits perfectly in my wallet without adding much bulk.I have it set to alert me if my wallet and phone get too far apart. This has already saved me a few times—once I left it at work, another time at home, and once I even left it in my car. Getting those alerts is super helpful.One of my favorite things is that it’s rechargeable, so I don’t have to buy a new one every year. Just make sure to keep the charging attachment somewhere safe so you don’t misplace it. I’ve had mine for almost a year and haven’t needed to charge it yet, so the battery life is excellent.The only small downside is that if your wallet is very tight, you might accidentally press the button on the tracker, which causes it to beep. I’ve mostly avoided this by placing the card in the center of my wallet where it’s less likely to be squeezed.Overall, this is a great product—compact, reliable, and cost-effective in the long run.

I have a friend who is rapidly losing his memory. He constantly loses his wallet and phone. I placed one of these devices in his wallet and it has made a world of difference. According to the literature, it will stay charged for a year. We will see.The signal lags a little behind since it is using cellular towers, but I can still tell where he left the wallet if that should happen. I purchased Eufy because their products are well made and function as advertised.

This thing is exactly what I wanted—super slim, fits in my wallet without bulking it up, and connects almost instantly when I open the app. The rechargeable battery is a game changer, especially compared to Tile or AirTags that need replacements.Location accuracy has been reliable, and the sound alert is loud enough to find it in couch cushions or under a pile of clothes. Honestly, it’s doing everything right.No complaints so far—Eufy nailed it with this one.

This is nice to have in case I lose my wallet. Seems to work well with IOS. Only problem is that I occasionally push the button whenever I sit thus the battery does not last all year like it states. Maybe 3 months for me. I guess if I stored my wallet in my front pocket I wouldn’t have this problem.

This review is less about the product-but mostly about Euffy’s customer service.TLDR; Bought this for air travel and now I’m returning it because Euffy can’t/wont provide the full battery specs.I initially bought this tracker for my luggage because it has a more inconspicuous presentation than an Apple Air Tag. I also liked the idea of this tracker being rechargeable. It seemed to be a more cost effective approach than buying the disposable version of this tracker and having to replace it every year.But that’s where the problem starts. There is no information listing the battery specs anywhere. Not here. Not on Euffy’s site. Nowhere. The most to be found, is that the battery is “rechargeable”. For intended usage, like wallets, that is fine. But when having to deal with airlines, tsa, and the FAA, that’s not enough information.So I reached out to Euffy Support, requesting more information about the battery. I told them about the threshold limits the FAA allows for lithium/rechargeable batteries and I asked what battery specs are.Their response:“It is a rechargeable battery.“When I pressed for more than that, they told me “The E30 doesn’t use power.”I decided to ask the question under the Amazon listing, the Euffy rep said that they don’t have access to that information. Although I appreciate the honesty, that was enough for me to decide to file for a return. The absence of information is enough to indicate that this device will not work with the application that I am looking for.

Does exactly as advertised. So easy to hide. Well built and works great.

I had an AirTag wallet, but it was uncomfortable and bulky. I’m a minimalist when it comes to wallets, so this was perfect. It’s thin, about the thickness of two credit cards, and the future proof feature of being rechargeable is awesome. The alarm is also louder than the AirTag, so easier to find if you need it. Adding to FindMy just like an AirTag is a nice feature, just be aware that you may have to add it to the eufy security app first to activate it. Seems to work great, and I’ve been quite happy with it.
