introducing K Ring, the world’s first contactless payment ring (formerly known as Kerv)

For more information: K Ring defines the next-generation of wearable payment technology. Even more convenient than a contactless payment card, Kerv Ring (unlike Apple Pay, Android Pay and Samsung Pay) never needs pairing with a phone or charging – it just works. K Ring is powered by a prepaid Mastercard account, and is different to a balance transfer credit card or a cashback credit card in that you can only spend what you load, so there’s no risk of getting into debt. If you’re looking to buy an Oyster Card, you might want to get K Ring instead: no more fumbling around at the ticket barrier for your Oyster Card or contactless card … just knock on the Oyster reader to open the gates. K Ring ensures you always have money on hand. K Ring being used on the London Underground:
