McLEAR Smart Ring

The ceramic McLEAR Smart Ring is both a convenience and a conversation starter. You can use it to pay contactlessly in shops and on public transport, thanks to the installed NFC chip. Once you’ve paired the ring with the companion app, it assigns a secured isolated bank account that sits between any of your cards (Visa, Mastercard, and Amex). The bank account requires taking a picture of a form of identification such as a passport or your driving license. Once your account is done, McLear says that information is deleted and not stored anywhere. Once you’re all set up, you’ll need to perform a closed-fist gesture (like knocking on a door, not like punching). You can get this beautiful and practical ring for 120$.
