This credit-card-shaped tracker is like an AirTag but better

TL;DR: The KeySmart SmartCard is the thinnest Apple Find My-compatible tracker, designed to fit in your wallet, charge wirelessly — and it's just $29.97 (reg. $39.99) through March 31.

Losing your wallet is frustrating. Digging through couch cushions, retracing your steps, and panicking over lost cards is not how anyone wants to spend their time. That's why we are rejoicing over the KeySmart SmartCard. It's the thinnest Apple Find My-compatible tracker designed to seamlessly fit in your wallet or ID badge — unlike the bulky, oddly shaped AirTag.

At less than 2mm thick, the SmartCard slides into any wallet slot, providing powerful tracking without the extra bulk. And unlike the AirTag, which requires disposable battery replacements, the SmartCard is rechargeable with any Qi-enabled wireless charger and lasts up to five months per charge.

The SmartCard is built for real-world use. It's IPX8 waterproof, meaning it can survive up to an hour submerged in water. This makes it ideal for travelers, commuters, and anyone who needs a durable tracking solution. Plus, its built-in lanyard slot allows you to attach it to ID badges or security cards, so you never have to deal with lost office credentials again.

With Apple Find My integration, the SmartCard offers real-time location tracking, separation alerts, and Lost Mode, so you don't misplace your essentials.

You can play a sound to locate it nearby, get notified if you leave it behind, and even use Lost Mode to display contact details if someone finds it. No bulky keychains, no weird shapes — just ultra-slim, ultra-smart tracking.

Don’t wait until you misplace your wallet again. Get this smarter way to track your essentials while it's on sale.

For a limited time, grab the KeySmart SmartCard for just $29.97 with free shipping instead of $39.99, but only through March 31.
