Apple Pay is not accepted at Walmart stores in the U.S.
Use a Walmart-approved payment method instead, such as a debit card, credit card, Walmart gift card, cash, or Walmart Pay.
If shopping in the Walmart app or on Walmart.com, check whether Apple Pay is available at checkout in your region.
For in-store purchases, use Walmart Pay in the Walmart app if you want a mobile payment option.
To use Walmart Pay, open the Walmart app, sign in, select Walmart Pay, and scan the QR code at the register.
If you want to use Apple Pay, consider shopping at retailers that accept contactless payments.
