Yes, Walmart's self-checkout system typically allows customers to manually type in credit card information if the physical card is not available [1]. This means that if you have a virtual card provided by your bank, you should be able to enter the card details manually at the self-checkout.

To manually enter your credit card at Walmart self-checkout, follow these steps:

1. Begin the checkout process at the self-checkout kiosk.
2. When prompted for payment, select the option to pay with a credit card.
3. Look for an option to manually enter the card details.
4. Enter the card number, expiration date, and any other required information using the keypad or touchscreen.
5. Follow the on-screen instructions to complete the transaction.

It's always a good idea to check with a store associate to confirm their specific policy and ensure a smooth transaction, as policies may vary slightly between different Walmart locations.
