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

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.

The eufy tracking card is a lifesaver. I’ve been using this product for a year and it has helped me find a missing wallet multiple times. Works great with Apple FindMy and fits in your wallet like a credit card. Much better than trying to put an AirTag in your wallet lol. This version is rechargeable and I highly recommend.

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.

This card solves my problem with the previous non-rechargeable one...it can be recharged. Otherwise it's the same product...with the same minor flaws. It has some push-button features for finding your phone, but even buried in my wallet, somehow that button gets pressed occasionally. You can turn these features off, but that turns it into a single-role device, albeit the most important one, which is tracking. This card is slightly heavier than the old one, but not to any significant manner. But so far so good.

Easy Setup. Solid quality. Reliable.

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.

I’m very happy with this purchase! My son has a habit of misplacing his wallet, and this SmartTrack Card has been a lifesaver. I had the older generation, which lost its battery after two years and wasn’t rechargeable, so this model is a perfect upgrade. It works flawlessly, is the same size as a credit card, and the rechargeable battery is a huge convenience. I’m so impressed that I’ll be buying more as gifts—it’s hard to overstate how handy this really is.

The unit does seem to connect to both the Eufy app and Apple Find My app. Where i have a problem is after being connected for about two weeks the unit seems to shut down and is no longer detectable by either app. It seems like the Bluetooth network stack gets corrupted and all connection to the phone is dropped until the item is rebooted and formally reconnected to the phone and apps as a new device. I discovered this to be the case when my wallet was lost with the tracker in it and was unable to find any location information for it. After a day and a half i found it sitting on a cabined shelf in the loft. The card was still inside, there was more than sufficient power in it but it was totally disconnected from my phone... this seems to happen after having it active for more than two weeks. I will provide further updates if it works better in the coming months. I have a trip to Poland coming up will provide update on how the device works in comparison to apple tracker.

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!
