AirCard Wallet Tracking Card
Apple’s AirTag is a great way to track items but it doesn’t fit well into a wallet. Rolling Square’s AirCard offers a similar global tracking function and is the size of a credit card. The aluminum card measures 2.2 mm thick and doubles as an RFID blocker and an NFC/QR code business card. It also has a built-in 105dB speaker, so you can easily ping its location.
