Walmart Now Lets You Pay With Phone At All 4,600 US Stores Via Walmart Pay

An anonymous reader writes: Walmart will now let customers make purchases with their phone at all 4,600 of its stores in the U.S. The feature is called Walmart Pay and it works by letting the cashier scan a QR code on a customer’s phone screen to complete their payment. The technology is different than Apple, Samsung, and Android Pay, which involves tapping your phone next to a payment terminal with NFC. The company wants to make shopping easier and faster, and with its own payment app, Walmart can get insights into consumer behavior, though it says it won’t use the data without a shopper’s permission. Walmart says no payment information is stored on users’ phones or at registers — card information is stored on Walmart servers. Note: Samsung Pay also uses magnetic secure transmission (MST) to make purchases. When a smartphone with Samsung Pay is held against a register with a magnetic stripe terminal, the phone emits a magnetic signal that simulates the magnetic strip found on the back of a credit or debit card.
