Students test finger vein payments at UK supermarket

British supermarket offers ‘finger vein’ payment in worldwide first — The Telegraph — “It works by using infrared to scan people’s finger veins and then links this unique biometric map to their bank cards. Customers’ bank details are then stored with payment provider Worldpay, in the same way you can store your card details when shopping online. Shoppers can then turn up to the supermarket with nothing on them but their own hands and use it to make payments in just three seconds.”
