eufy 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

Easy to install. Credit card size. Nice and thin. Been working as advertised. Dont need to create a username on eufy website. Using it to track my bicycle. Cant use airtag, as this is designed for "lost" items not stolen items.

So far the item is working as expected. It’s nice to have a rechargeable option as opposed to needing to buy a replacement. Time will tell if it hold up to being in my wallet in my back pocket. In the tests if done to use its location tracking. It has worked as suspected. My only wish is that it has precise location finding like an AirTag but I know Apple isn’t going to allow that with a 3rd party. I’m glad they allow it to work with find my.

I bought this initially thinking that because it uses Apple's "Find me' technology it would be perfect to put on my eBike in the event it's stolen. I then dug deeper and learned it will only get you to within 150 feet (at best) of the object you put it on. That could easily be one of six or so houses. Rather than return it, I mounted it on my bike in a place where if the would be robber looked just a little bit, they could find it and take it off and throw away before taking the bike. The Air Tag (gets you to within 10 feet of the object) is on a place on the bike where even if they figured it out where it is, it's going to take them awhile to take it off. This may not be the review their looking for but this is how I'm planning on using it, and if it works as intended, G_D forbid my bike is stolen, then it's worth it!

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.

Works well. Connects to my FindMy, and it's accuracy isn't bad. You do have to walk a fair bit away from it to be notified that you've left it behind. The battery doesn't last as long as other reviews say, for me it lasted about 4 months before notifying me it was on low power. Decently thin, around two cards thick. Fits well in my wallet and I'd say its worth the money, as I haven't had any problems with it. The setup took around 10 minutes, and sound is decently loud.

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.

Worked as advertised easy to add to FindMy and their app; Easy charging.

The eufy Security SmartTrack Card E30 is a great alternative to Apple AirTags, and I highly recommend it! ✅ More Affordable Per Tracker – Compared to AirTags, these offer better value, making it easier to track multiple items without breaking the bank. ✅ Rechargeable = No Battery Replacements! – Unlike AirTags, these are rechargeable, eliminating the hassle and extra cost of replacing batteries. ✅ Works Seamlessly with Apple Find My – No extra apps needed—just like AirTags, these integrate directly into Apple’s Find My network, making them easy to locate. ✅ Slim & Versatile Design – Slightly thicker than a credit card, they’re perfect for slipping into luggage pockets, wallets, backpacks, and more. Overall, these are a must-have for travelers and everyday use, offering premium tracking at a lower price with the bonus of being rechargeable. 5 stars!

Buongiorno. Ottimo articolo, questo è il secondo che acquisto. Permette di ritrovare il portafoglio, che spesso lasciamo da qualche parte, soprattutto noi uomini. È sottile e, in base all’utilizzo che ne faccio, l’ho ricaricato un anno fa ed è ancora carico. Lo consiglio: pochi soldi ben spesi.

Su reducido grosor y la gran duración de su batería recargable son sus puntos fuertes. Comparte todas las funcionalidades de los AirTags a excepción de la búsqueda cercana. Una función llamativa y útil en las distancias cortas como por ejemplo dentro de una habitación aunque activando el sonido de la tarjeta se puede más o menos suplir. Soy muy despistado por lo que tengo bastantes AirTags que me han evitado incontables pérdidas de llaves, carteras, etc con los consiguientes quebraderos de cabeza pero no son perfectos y es que aunque sus pilas duran bastante, al tener tantos si no se agota una, se agota otra. Estoy deseando que salgan los AirTags 2 que se supone están al caer y confío en que sus baterías sean recargables como las de esta tarjeta Eufy. Si el principal uso que vas a darle es la cartera, el reducido grosor de esta tarjeta es una ventaja insalvable para la versión actual de los AirTags.

ممتاز انصح بها

Très fin et léger, le produit s'appaire à Localiser d'Apple en quelques secondes et peut être appairé dans le même temps à l'application Eufy, avec quelques options en plus dans celle-ci. Qualité remarquable, recharge rapide et endurance annoncée excellente. En terme de suivi, il a été parfait depuis son activation. Recommandé!

This SmartTrack Card is seriously one of the most useful gadgets I’ve bought. The design is sleek and compact, slightly thicker than a credit card but slim enough to fit easily into any wallet. The build quality is excellent, and it feels sturdy and well-made. The best feature of this new version is that it’s rechargeable. The older model wasn’t, so once the battery ran out, you had to replace it. With this one, you can simply charge it when needed, and it holds its charge for a long time. That alone makes it worth every penny. Another cool thing is the built-in button that works both ways. If you lose your wallet, you can use the app to make the card beep. The sound is loud and clear, so it’s easy to find. If you lose your phone, you can press the button on the card to make your phone ring. It’s so handy! It’s also fully compatible with Apple’s Find My app, which means you can add it to the app and track it easily, or even make it play a sound directly from there. It’s seamless and works perfectly with iOS. I had the older version of this card and loved it, so when I saw this new rechargeable model, I ordered two right away one for myself and one for my wife. We’re both super happy with them. Honestly, I think everyone should have at least one of these for their wallet. Highly recommend it!
