Idea: Food accounts at banks
I'm poor and have a LINK (EBT/Food Stamps) card, and I think it's great having a portion of money that is specifically for food.
It'd be nice to be able to put my money (if I had a paycheck) into a "food" account at my bank. Like when receiving direct deposit, automatically transfer $200 to my food account, and it's a checking account, but it's a debit card that only lets me purchase items that are purchasable on LINK.
This could be extended to cards that only do restaurant purchases. Basically budgeting, but there's infrastructure supporting it.
