I've been testing this Bluetooth tracker for a month — and it's the perfect way to keep track of my phone and wallet

Everyone knows how much I love MagSafe wallets. While some of them have integrated trackers that let me keep tabs on my phone and wallet, they’re often bulky and use proprietary chargers. That’s why I switched back to one of those credit card sized Bluetooth trackers to see if they’re any more practical.

For more than a month now, I’ve been using the Rolling Square AirCard Pro to make sure I’m not leaving behind my backpack or iPhone 16 Pro Max. Similar to some of the best key and wallet finders, the AirCard Pro is razor thin and fits inside any ordinary wallet — but it has two features that make it stand above other trackers I’ve used.
