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.
Which will you choose?
No charging
Unlike smartphones and smartwatches, K Ring never needs charging, so you'll always be able to pay
No pairing
K Ring works all by itself, so you don't need to pair it with a smartphone to make a payment
Scratch resistant
Engineered from zirconia ceramic, K Ring’s outer shell is hypoallergenic and almost as scratch-resistant as diamond
Waterproof
K Ring’s electronics are sealed with a waterproof hypoallergenic resin, and it's just as happy in the sea as it is in the shower
Always welcome
K Ring is welcome anywhere that accepts Mastercard contactless payments, which is almost 40 million retail locations worldwide – just look out for the contactless payment symbol
Always secure
For extra peace of mind, you can switch your K Ring on and off, set restrictions and get live transaction alerts – all managed within your K Account
ABN AMRO is the first bank to offer their customers the opportunity to link K Ring directly to their bank accounts.
