Shoppers on Richmond High Street in London will be able to use a face recognition payment system after the launch of a new smartphone app.
The new PayPal app for iOS, Windows OS and Android phones highlights nearby shops and restaurants that accept the new system,.
To make a purchase the customer checks in by clicking on the required retailer, and sliding an animated pin down on their screen. The customer's name and photo then appears on the shop's payment system and the retailer charges them by clicking on their image.
The customer then receives an alert on their phone to let them know how much they have paid as well as PayPal's usual email receipt.
Richard Garcia, owner and proprietor of Cook and Garcia cafe on The Quadrant in Richmond, said: "We've been using PayPal's check-in service within the business for several months, and have found it really efficient.
"Customers don't have to worry about having cards, cash or change, just their phones. It is the quickest transaction through the till, which means less queues and we never have to turn down a sale, both of which are great for business."
PayPal head of retail services Rob Harper said: "PayPal first brought 'pay by mobile' to the UK high street two years ago. Through our Richmond initiative, we're pleased to help local businesses of all sizes offer a new more personal experience, while never having to turn away customers who don't have enough cash on them to pay.
"Now locals in Richmond can leave their wallet or purse at home and be the first in the country to use their profile picture to pay.
"This is another step on the journey towards a wallet-less high street, where customers will be able to leave their wallet or purse at home and pay using their phone or tablet. We predict that by 2016 this will become a reality."
