KeySmart MFI-Certified SmartCard Wallet Tracker Card, Compatible with Apple Find My App, Rechargeable Thin GPS Item Finder for Luggage Tag, Smart Bluetooth Tracking with Key Chain Hole Black, 1 Pack

Works fine for what I wanted. Similar to other "find my 'products'" this smart card tells me the general location within a specific radius of where my item is. It appears as a credit card sized tracker that requires specific criteria to be met. You meet the criteria and perform the actions and the card works...every time. It's battery life is adequate. No issues charging it, you do need a wireless charger and you should follow the online instructions if you are having issues. It appears as durable as a credit card, so fold it in half and it's busted, just like your CC. Weighs more than a credit card, but again does the job. I'm happy with the purchase. Biggest downside for me/us is that I use an Android phone..and this works exclusively with Apple - so I have to pull up a tablet to locate my item if it's misplaced. So keep that in mind, but that's my problem not yours.

PROS: 01. Slim Compared to other products this one is much more slimmer. As shown in the second photo this one is as slim as 2 normal credit cards. Making it easy to fit in many wallets and card holders. 02. Physically Flexible Some products of the similar category have a hard plastic construction making them impossible to flex. That there is an issue to those who carry wallets in their back pocket which is prone to being bent to an extent. With this tracker the construction is softer thus reducing the chances of breakage or cracks. 03. Discrete Unlike other trackers this has little to no branding. In real life this looks more similar to an apartment building keycard. If your wallet was to be stolen, thieves wouldn't pay much attention to it unlike an AirTag and would be less likely be spooked by it and throw it away making it much easier to track. 04. Loud alarm The included video demonstrates how loud it can get. For something so slim the sound is remarkably loud. It's almost as loud as an AirTag. 05. Wireless Charging When the charge runs out, other brands have opted to provide you with a replacement card for a fee or provided a proprietary charging attachment. This charges wirelessly thus eliminating the dependency on replacement services or having to use a proprietary charger that you may loose or may not function. Wireless chargers can be found almost anywhere and if your phone supports reverse wireless charging you don't have to rely on anything else. 06. No Power Off Button There is a small button on the card but it is only used for initial pairing and factory reset. After paring has been completed the button no longer functions until you remove it from your findmyapp. After which it becomes a "reset" button. This ensures that the card does not turn off while be carried in your wallet by accident and it can't be turned off by thieves. 07. Battery Life I have yet to test it's battery life but it is rated at one year. With it's charging capability that's a plus. CONS: 01. No U1 Chip DO NOT EXPECT PRECISE TRACKING! Like most trackers of the same kind this lacks an U1 chip which would have allowed precise tracking. Unlike AirTags you will not get compass like directions on your phone, instead it'll gives you a radius of where the card is. The tracking is mostly done using bluetooth so you get a range about 30ft. VERDICT: Given it's price, discreteness and charging capabilities I'd say this a superior product even with its minor con. I much rather be SAFE THAN SORRY.

**** UPDATE**** WORST CARD GPS you will ever have. NEVER works when you need it and now stopped workign completely. Spent 4 days looking for my phone, wouldnt beep, fully charged, DONT WASTE your money with this card, almost had to cancel my trip becuase it wasnt communicating with my Find MY. Terrible, buy another brand. ZERO stars I'm glad I forgot to update my previous review after reciving a new card. I cannot say enough TERRIBLE things about this "smart-card". The first one I got was defective, hence the review below but I THOUGHT that the next card I had now was working. Spoiler alert, DONT BUY THIS CARD. I bought it again and before using it in my new wallet in November I fully charged it. They have now changed the listing to card staying charged for up to 5 month, it was more before, I belive it said up to 12. Regardless, its been 2 months, today I lost my wallet, went to Findmy phone app only to see the card battery died back in late December. Luckliy I found my wallet and now the card doesnt charge at all. The wirelss just blinks so it wont even charge!!!. Another $40 doen the toilet. DO NOT BUY THID ITEM. Just not me. Attached you’ll see my video review. I’ll add that we have 6 devices and 4 AirTags currently on Find My so we are not strangers to pairing. We tried multiple times in the past 3 days. Fine my does not recognize the card. Shame, I REALLY wanted this and would have gotten more as these are easy to hide from thieves Do not recommend.

I'll update this in a few months once I get more used to how long the battery lasts in real world scenarios. Initial impression though is that it's a great solution for use cases where AirTags would be annoying due to their shape or thickness. Obviously it's great in wallets, but it's similarly useful in all kinds of random things like camera cases where you can stuff it between the foam and the hard shell, or anywhere you worry a thief would easily spot an AirTag because that's what they're looking for to see if the thing they stole has one. That being said, what I did not realize before purchase is that apparently only AirTags support micro location, where you can use Find My to walk around the house and have it point you in the direction of the signal. (Typical) Apple has not opened that functionality up to third party devices yet. So, if I'm looking for my wallet with one of these in it, I have to walk around the house until I'm within range to be able to set off the audible alarm. That's a huge disadvantage, but not enough of one for me to carry a hideous wallet that has an AirTag holder built into it, or to ruin one of my nice wallets stuffing an AirTag into it.

This smart card did exactly what I wanted without making my wallet bulky. It’s about the size of a credit card and slides into a card slot easily, so I don’t feel like I’m carrying a big tracker around. Once it’s in there, you pretty much forget about it until you actually need it. Setup with Apple’s Find My was super simple. I opened the app, added a new item, and it connected within seconds. Now I can see where my wallet is on the map and make the card play a sound when I misplace it around the house. The alert is loud enough to hear from another room, and the connection has been reliable so far. I also like that it uses the existing Find My network instead of yet another separate app. Everything is in one place, and I don’t have to manage extra logins. The only thing to be aware of is that you do need to keep an eye on the battery and recharge it occasionally, but that’s a fair tradeoff for something this slim. If you’re the type of person who occasionally leaves their wallet on a counter, in a jacket, or in the car, this is a simple, low-profile way to have some backup and peace of mind.

This SmartCard is actually pretty clever. It fits right in your wallet, so you always have a charger on you without carrying extra cables. The fold out connectors work smoothly, and it charges well for quick top ups. It is lightweight, easy to stash, and just a handy backup to have when you are out and about.

I wanted to love this item so bad and almost purchased a 3 pack. I had been researching different products for my wallet. The design is perfect for this need. Button is small enough you wouldn’t actually push it accidentally. Battery life is great. Connects with find my app seamlessly. The sound is similar in volume to an air tag. But out of no where (and when I need it most), the sound quit working 4 months into using it. I just dealt with it. I just got it out to charge it for maybe the 3rd or 4th time since February. I decided to see if there was a warranty. According to the website, you get a warranty if it’s purchased through their website ONLY. So is the company being cheap or are they purposely selling trash on Amazon? Because, that’s what it looks like.

Purchased three pack. First charged just fine but cannot activate it. Procedure in directions did not activate the card. Found different procedures online but none worked. So one in three worthless. Went to customer support for warranty claim (purchased 8 months ago so cannot return to Amazon) and it was too much of a hassle. so two stars since it charged up at least. One of three. Will they the second card and then will update this review. Not a very good first impression. On edit I will bump this up to 3 stars. When I examined the other two cards in the 3 pack I could easily feel a small bulge where the activation button is located and an obvious detent click when pushed. Going back to the first card, the bulge was there but much thinner and slightly off to the side. Pushing carefully on that slight bulge I was indeed able to start it up. So all good. Slight manufacturing defect caused so much grief.
