Florida Walmart stores can now take payments through the retailer's mobile app, which will allow many customers to bypass the card reader at the register.
The retailer first announced the launch of Walmart Pay in December, but only for a limited number of stores. It is compatible with Apple, Android or any smartphone capable of running the Walmart App.
Rather than cash or cards, customers can pay at the checkout line electronically by opening the Walmart app, entering their PIN under the Walmart Pay prompt and then scanning a QR code displayed on the register screen. The app will also save an electronic copy of the receipt.
The new payment feature is being added to the existing Walmart app, which among other things allows customers to refill prescriptions, store gift cards, record shopping lists and make online orders. Walmart said the app already has 20 million active users.
Other payment systems include Apple Pay, Android Pay and Samsung Pay. Walmart claims to be the first retailer with its own app and does not accept the other systems.
