Always on hand
K Ring is the world's first contactless payment ring, powered by Mastercard and welcomed at over 40 million retail locations worldwide.
With K Ring, there's no need to handle cash or touch a PIN pad so you can leave your cards and phone safely in your pocket.
K Ring is free to load and free to use, and with the new contactless limit of £45, it's now even easier to safely pay in shops and on public transport – just look out for the contactless payment symbol.
Always looking good
Engineered from scratch-resistant zirconia ceramic, K Ring is available in a wide range of sizes and colour combinations.
Which will you choose?
You can’t make accidental payments with K Ring because it must be within 4cm of a contactless reader, with your hand in the correct position.
Powered by Mastercard, K Ring benefits from all of Mastercard’s security features – and for extra peace of mind, you can easily switch it off and on at any time.
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 is waterproof and won't be harmed by soap or alcohol-based hand sanitiser – so keep washing those hands!
