Tesco's in-house mobile payment app PayQwiq has been around for a few years now, though it was only accepted in all Tesco stores from the beginning of this year. PayQwiq doesn't roll off the tongue all that well, but today it assumes a new name: Tesco Pay+. As always, the app functions as a virtual Clubcard and keeps a record of your receipts, but its main purpose is allowing you to brandish your phone at checkouts to pay for up to £250 of shopping with a tap.
