Mobile-payment services from Apple, Google and Samsung all rely on wireless technology called NFC. Customers can put the phone away and an e-receipt application will be sent to the app. That connects the phone to the basket of items they're checking out. At the register, they open up the app and then activate the camera function to scan a QR code on the reader. This holiday season, Walmart added new features like allowing online shoppers to check in once they get to the parking lot so they could have their online orders ready for pickup.įor the new system, shoppers download the Walmart app and then select a payment method. Twenty-two million customers use the Walmart app each month, and more than half of Walmart's online orders come from a mobile device. It's simple, and it's a secure way for customers to use their smartphone.' 'We are creating a seamless shopping experience that includes payment,' Neil Ashe, president and CEO of Walmart's global eCommerce, told reporters on a conference call Wednesday.

The move signals that Walmart believes it's best to build its own system to better serve its customers, even as it backs a retail industrywide mobile payment program that is in test phase. None of them has cracked the market so far. Walmart has moved into the field as Apple's 1-year-old tap-and-pay system is being expanded to other merchants and several months after Google launched the Android Pay mobile wallet app and Samsung came out with Samsung Pay. It's part of Walmart's overall mobile strategy to make shopping easier and faster, but the launch is the latest salvo in the battle for mobile payments that's in the early stages. It plans to launch the payment system called Walmart Pay in all 4,500-plus U.S. It started testing the new payment feature Thursday at its stores in the Bentonville, Ark., area, where the retailer is based. Wal-Mart Stores Inc., the world's largest retailer, said it's launching its own mobile payment system that will allow shoppers to pay with any major credit or debit card or its own store gift card through its existing smartphone app at the cash register.

NEW YORK - The mobile payment wars are heating up.
