Electronic Benefits Transfer, or EBT, is a system through which welfare organizations can rapidly send people their benefit payments so they can use them more efficiently.
If you have an EBT account, you can make a payment at any Walmart store online through both EBT Food and EBT Cash in 44 U.S. states —the exceptions are Alaska, Arkansas, Hawaii, Louisiana, Manie, and Montana.
However, "residents in Arkansas, Alaska, Louisiana, Maine, and Montana may use their EBT benefits card in-store at checkout. Hawaii does not have any Walmart stores on its islands."
