7-Eleven announced today that it’s installing scan-and-go technology in 14 Dallas-based stores this week, according to Digiday. The technology will allow customers to scan the barcodes of items they want to buy and then pay through their phone, either with a card, Apple Pay, or Google Pay.

Customers will need the 7-Eleven rewards app to complete the transaction. People will have to then scan a QR code on their way out of the store to confirm payment. The entire purchasing process is done through the 7-Eleven rewards app, which will determine when customers are within range of an equipped store and will load the feature automatically.
