K Ring is welcomed anywhere that accepts Mastercard® contactless payments – which is almost 4 million retail locations worldwide – including New York City
Unlike smartphones and smartwatches, K Ring never needs charging, so you'll always be able to pay
K Ring works all by itself, so you don't need to pair it with a smartphone to make a payment
Engineered from zirconia ceramic, K Ring’s outer shell is hypoallergenic and almost as scratch-resistant as diamond
K Ring’s electronics are sealed with a waterproof hypoallergenic resin, and it's just as happy in the sea as it is in the shower
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.
