Last month, Walmart Pay widely expanded to Alabama, Georgia, Indiana, Iowa, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Nebraska, North Carolina, North Dakota, South Carolina, South Dakota, Tennessee, Virginia, and the Washington D.C. capital area. The service initially launched in Arkansas and Texas in May.
Walmart Pay is built into the Walmart app [Direct Link] for iOS and Android and works at any checkout lane with any major credit, debit, pre-paid, or Walmart gift card.
The payments solution is based upon a QR code checkout process that involves opening the Walmart app, selecting Walmart Pay, activating the camera, scanning the code displayed at the register, and waiting for the cashier to finish bagging your items. An electronic receipt is automatically sent to the app.
Walmart Pay is now available at more than 4,600 stores in all 50 states.
Walmart is among a handful of retailers that have refused to support Apple Pay since its American launch in October 2014. The retailer was originally committed to the Merchant Customer Exchange (MCX) consortium and its now indefinitely postponed payments service CurrentC before launching Walmart Pay.
In late 2015, Walmart senior vice president of services Daniel Eckert said that Walmart Pay allows "for integration of other mobile wallets in the future," providing at least some hope that the retailer may eventually accept rival payment services such as Apple Pay, Android Pay, and Samsung Pay at its stores.
Walmart Pay's resistance to Apple Pay continues despite some other large U.S. retailers including Best Buy and Rite Aid reversing course and accepting the iPhone-based payments service at their stores. Walmart rival Target, meanwhile, is developing a QR code-based mobile wallet solution of its own.
The Walmart app [Direct Link] is free on the App Store for iPhone and Apple Watch.
Update: Walmart announced on Wednesday that Walmart Pay is now available at all of its more than 4,600 U.S. stores nationwide.
