Tangem Ring

Tangem Ring is a ring-shaped hardware wallet using the same secure element chip as the Tangem Wallet card. Private keys are generated and stored inside the ring, and transactions are signed by tapping the ring against an NFC-enabled smartphone running the Tangem app. Each set includes one ring and two backup cards that form a shared wallet with distributed key backup. The ring uses a zirconia ceramic shell rated IP69K for waterproofing and pressure resistance, and does not require batteries or charging.
