When you check out at Walmart (at the register or self check out, does not matter) click "Walmart Pay" on the screen where you slide your card and click "Walmart Pay" on the bottom left hand corner on the mobile Walmart App. It will ask you to create a 4 digit code, just make it "1111" or "2222" so it's quick to enter. It will not ask you for a pin (cc security code) unless it says "requires pin" on the app. If it says that, don't even bother. Make sure to use the wifi in store or a VPN for your own protection. I highly recommend not using this at a Walmart near you. If there are gift cards on the account, it will let you know, You can use those to buy what ever, electronics, toys, tobacco protducts, guns, ammo, etc. Hidden Content: You must 'reply' and click 'Like' before you can see the hidden content.
