As an alternative to using physical cash or cards, Tesco customers may now opt to pay via the multinational grocery retailer's 'PayQwiq' app. With this app for iOS and Android, shoppers are able to store their debit card and Tesco Clubcard details and convenient pay for purchases of up to £250 at a till just by having on onscreen QR code scanned.
Once an individual's unique code has been scanned with the app, a payment is settled and points are automatically added to one's Tesco Clubcard rewards account.
As an alternative to using systems like Apple Pay and Android Pay, retailers are developing their own payment systems. This includes Waitrose's Quick Check and Kohl's Pay, among others.
