Always on hand
Carrying a wallet or purse isn’t always practical, so we made Kerv, 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.
Always looking good
Available in a range of sizes, Kerv is engineered from scratch resistant zirconia ceramic and comes in 14 colour combinations. Which will you choose?
Unlike smartphones and smartwatches, Kerv Ring never needs charging, so you'll always be able to pay
Kerv Ring works all by itself, so you don't need to pair it with a smartphone to make a payment
Engineered from zirconia ceramic, Kerv Ring’s outer shell is hypoallergenic and almost as scratch-resistant as diamond
Kerv Ring’s electronics are sealed with a waterproof resin, and it's just as happy in the sea as it is in the shower
Kerv is welcome anywhere that accepts Mastercard contactless payments, which is almost 40 million retail locations worldwide – just look out for the contactless payment symbol
It was so easy!
