Look, we love Apple AirTags as much as the next person who frequently misplaces their keys. But let's be honest: that adorable UFO shape is about as wallet-friendly as a brick. For five years, we've been jamming circular pucks into card slots, and it's been a mess.
Enter the UAG Metropolis by Urban Armor Gear, a company that usually makes phone cases tough enough to survive a zombie apocalypse. This is a tracker card that actually fits alongside your credit cards, measuring 3.4 x 2.2 x 0.1 inches - roughly the thickness of four credit cards stacked together. It's made of a tough polycarbonate shell with ultrasonically welded edges, and it's IPX4-rated, meaning it can handle splashes. The author even immersed it multiple times, and it kept working, because apparently that's a thing we do now.
Durability is a legitimate concern for slim tracker cards, given that wallets experience a lot of bending. The author tested this by carrying the Metropolis in a back pocket without a wallet for over a week. Despite the abuse, the tag remained unaffected. Because if your back pocket can't handle a tracker, can it handle anything?
Inside is a 110 mAh battery that lasts about five months under normal use. When it's time to recharge, you can just plop it on a Qi or MagSafe wireless charger for a couple of hours. UAG says the battery is designed for 300 recharge cycles, which works out to over 100 years. So unless you're a Time Lord, you're probably fine.
The Metropolis works with both Apple's Find My and Google's Find Hub networks. You choose which network during setup, and you can reset it later if you switch teams. Bluetooth range is about 200 feet (60 meters) outdoors and 100 feet (30 meters) indoors - standard stuff. And no, RFID-blocking wallets don't affect the range, but metal wallets like Ridge can block the signal. Ridge's workaround: slide the tracker behind the money strap. Problem solved, sort of.
One standout feature is the 95 dB speaker, which is about as loud as a power tool. That's significantly louder than first-gen AirTags and on par with second-gen ones. Perfect for finding your wallet in a pile of laundry, deep in a sofa, or under a car seat.
The card also has a slot so it can double as a luggage tag. The author advises against using tracker tags for air travel because they can get bent. Instead, put it inside your luggage or use a rugged holder. Because nothing says "vacation" like a bent tracker.
At $45, it's competitively priced against other high-performing tracker cards like those from Ridge, Rolling Square, or KeySmart. The rounded corners and smooth, premium feel mean it won't wear through your wallet like some other cards. It's functional, stylish, and works seamlessly with both networks without requiring a third-party app. Plus, it will trigger an unknown tracker alert if someone tries to use it to stalk you. So you can rest easy knowing your wallet isn't also a spy device.
The UAG Metropolis is an excellent alternative to Apple AirTags if you want a tracker that fits in your wallet. It doesn't support Apple's Precision Finding, but its slim design, durability, and dual-network compatibility make it a strong contender. Finally, a tracker that doesn't make your wallet look like it's smuggling a UFO.
