Such a good question! - I wondered that too - but it is easy. You can take the numbers to your local Walmart and they can make a plastic card for you. Or, you can go online and order a plastic card. In any case you would want to put the numbers into the "Check gift card balance" section on the Walmart site to make sure the gift card it good, and good for the amount it is sold for. Hope all that makes sense... :-) Thanks for commenting.
To use a digital card all you do is go online buy a egift card using the code and pin and walmart will send it to your email and then you show the cashier your gift card that has a bar code and the cashier scans it and your good to go very simple to do no need to print out a card
