Walmart has announced that it has completed its rollout of Walmart Pay, its own take on mobile payments, to all of its stores nationwide. Availability covers more than 4,600 stores across the country, according to Walmart.

Walmart Pay hits the checkout lane at all Walmart stores across the U.S.

Originally launched in early December of 2015, Walmart Pay has seen a gradual rollout to stores over the past several months. As opposed to other mobile payment platforms like Android Pay and Samsung Pay, Walmart Pay uses QR codes that you scan from the Walmart app at checkout. Your associated payment card will then be charged and you'll receive an e-receipt in the app.

If you'd like to give it a shot, you can download Walmart's official app from Google Play to get started.
