Grocer Kroger launches QR code-based payment service

Grocery chain Kroger Co. rolled out a first-party mobile payments solution as it continues to rebuff third-party solutions like Apple's Apple Pay. Dubbed Kroger Pay, the app-based solution generates single use QR codes on a customer's device, which are subsequently scanned by a Kroger cashier upon checkout. The service allows users to associate any major credit or debit card with the digital wallet.
