Always on hand

Carrying a wallet or purse isn’t always practical, so we made K Ring, the world's first contactless payment ring.

Now you can leave your wallets, purses, cash, coins and cards at home and still pay for stuff – anywhere that accepts Mastercard® contactless payments – no PIN, signature, bank account or smartphone required.
