It’s been five years since Apple unveiled its AirTags. They were a pleasant surprise and addition to Apple’s lineup. They worked well, lasted about a year before needing a battery replacement, and fit perfectly into the Apple ecosystem. But the biggest compromise with the AirTags is the form factor. People have been wanting different AirTag form factors for years, especially one that can fit in your credit card without leaving a giant lump. That’s where KeySmart’s new SmartCard Pro comes into play. It’s ultra-thin, rechargeable, works with both Apple Find My and Google Find Hub, and honestly feels more premium than most trackers I’ve tested. Here is what you need to know!

KeySmart SmartCard Pro

The biggest upgrade to the SmartCard Pro is the new Atlas Gen 3 chipset. This new chip delivers much faster performance and a more reliable connection to your iPhone. This translates into a much faster ping to find and also a much longer battery life. Here are the specs:

  • Up to 24 months of battery on one charge
  • 350mAh battery
  • Supports Qi magnetic wireless charging (works with Magsafe)
  • LED light indicator
  • Support Apple Find My and Google Find Hub
  • only 2.4mm thin
  • under 20g in weight
  • IPX8 waterproof rating

The first thing that jumps out at you is the design. This card is ultra-thin but very well built. It does not feel flimsy at all; it feels like a high-end, premium metal card you would get from Chase or Amex. They also use a semi-translucent material so you can see where the battery is, the charging coil, and the pairing button. Love how this looks.

My experience

The best feature about this card is that you barely notice it when you put it in your wallet. As I said, it is basically the thickness of 2 regular cards or one metal card. So it disappears in your wallet among your cards. There is no awkward bulge that you would get from something like an AirTag. I tested this SmartCard Pro in multiple wallets, from metal slide-out wallets like PunCube to traditional leather bifold wallets to small MagSafe wallets. So even if you like carrying a slim wallet, you can fit this card and a few others.

There were three other standout features I wanted to highlight. First is the premium hardware approach KeySmart took here. The polished aluminum edges and transparent shell make it feel more like a thoughtfully designed tech accessory rather than a cheap plastic tracker. Secondly is the battery and charging. I love how you get two years of use on a single charge, and you can charge it wirelessly! It works with regular lay-flat chargers, has magnets so it works with vertical MagSafe chargers, and even has a small LED indicator to show you it is charging. Lastly, the speaker is amazingly loud. Some of these third-party trackers can be pinged, but the speaker volume is so low. So if something is lost in a couch cushion its still tough to find what you are looking for. The SmartCard Pro is loud enough that it is not an issue at all.

Also, the pairing process was very straightforward. Open your Find My app, then hold the pairing button down for 5 seconds, and it will immediately pair with the Find My network. You name it, whatever you want, and voila, it is paired! So if you are in the market for a new wallet tracker, whether for yourself or as a gift, this one is worth considering.

Pricing and availability

The new SmartCard Pro is available directly from KeySmart’s website. It is $49 for one, or you can get a 3-pack for $127 and a 5-pack for $174. The more you bundle, the bigger the discount per card. The SmartCard Pro is positioned as a premium wallet tracker, but with its rechargeable design, dual-network support, premium materials, and extremely slim form factor, I believe it is worth the price tag. Now, if you want to save a bit, you can still get the SmartCard Gen 3, which offers all the same features, but with only 11 months of battery. You can get that one for $39, and they also have bundles to take advantage of.

What do you think? Do you use Find My trackers? Do you like the AirTag? Let’s discuss below!
