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.

K Ring is welcome anywhere that accepts Mastercard contactless payments, which is almost 6 million retail locations worldwide – 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.
