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 secure

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 lock it and unlock it in the app.
