Flying Tiger is rolling out MishiPay, its mobile-based self-checkout mobile app, to its UK store. Earlier, the Copenhagen-based firm piloted its tech in Sweden, Denmark and Norway and deployed the Scan, Pay and Go service to its 30 retail outlets. Customers will use MishiPay’s mobile app to scan a QR code to enter and pay for the products they want to purchase. Martin Jermiin, the CEO at Flying Tiger, has reported that about 100,000 customers have already used the application for self-checkout service during its first phase. The tech is equally convenient for shops and customers.
