AirCard: The Convenient and Controversial Wallet Finder
Originally Published 2 years ago — by 9to5Mac

Rolling Square has created the AirCard, the world's first credit card-sized tracker that integrates with Apple's Find My network and also acts as an NFC and QR code-enabled virtual business card. The AirCard is designed to be a tracker for your wallet while also being able to use the Find My network. The secondary function is to have it be used as a virtual business card. The AirCard is 2.2mm in thickness and has a speaker with 105dB of sound so it can be located when lost.
