Walmart Pay is the latest to be launched by the US supermarket chain, which enables customers who pop in to do a little shopping to use their smartphone to pay for products thrown into the cart at checkout. This new feature is part of the company's app available on both Android and iOS.
So how does the system work? You'll first need to setup the apps with your chosen payment card. Then when you're at the checkout you'll be able to use Walmart Pay to scan a code displayed at the register, which will then forward an e-receipt to the app.
