Tesco is set to implement its mobile payment service in all of its UK stores by the end of the year after a successful trial period.
The service, known as PayQwiq, enables shoppers to connect debit and credit cards to the eponymous app and purchase products on mobile by scanning QR codes that display on-screen.
Shoppers can also simultaneously collect Clubcard points, without any need to scan their card separately.
The app, which is available for iPhones or Android smartphones, is similar to Android Pay and Apple Pay but can only be used at Tesco stores.
After the invite-only successful trial period, PayQwiq will now be available across 600 stores in London and Edinburgh as well as Plymouth and Northern Ireland.
"Customers can use PayQwiq to pay for their shopping and collect their Clubcard points all with one simple scan of their phone,” a Tesco Bank spokesman said.
“Feedback from customers who have used PayQwiq has been very positive, and we’re delighted to extend the availability of PayQwiq to Tesco customers in more locations."
