Always on hand

There are times when carrying a wallet or a purse is impractical, uncomfortable or just downright risky. Ask joggers and cyclists. Or surfers and sunbathers. Or clubbers and festival folk. Or even naturists – because you don't get many pockets in a birthday suit.

So we made Kerv, the world's first contactless payments ring. Now you can leave your wallets, purses, cash, coins and cards at home and still pay for stuff ... like a Jedi.

You can use Kerv to make payments anywhere in the world that displays the contactless payment symbol – no card, PIN, signature, bank account or smartphone required.

  • No pairing

    No pairing

    Kerv works all by itself, so you don't need to pair it with a smartphone to make a payment.

  • No charging

    No charging

    Unlike smartphones and smart watches, Kerv never needs charging, so you'll always be able to pay.

  • No worries

    No worries

    For extra peace of mind, you can use the app to switch Kerv on or off, set restrictions and get transaction alerts.
