20% OFF K Ring Gift Cards this Christmas

Want to buy K Ring for someone special but don't know their size? Our Gift Cards are just what you need ... and they're very easy to wrap 😉

Free to load, free to use

We don't charge you to load your K Ring via debit card or bank transfer – and we don't charge you when you use it to pay, either

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.

Always looking good

Available in a range of sizes, K Ring is engineered from scratch resistant zirconia ceramic and comes in 14 colour combinations.
