There are two kinds of cards.
The EBT card can be used for anything.
The SNAP card is the “Food Stamps” card and is used for food items that require some type of preparation - like Ramen.
So when you see people using “two” cards one is the SNAP for the food items and the second is the EBT for the other stuff.
Most states combine SNAP and TANF onto the same EBT card.
