Bitcoin Forum

I wonder if people can collaborate with Hospitals, Food markets, etc to create Bitcoin Cards that Crypto users can buy and help sponsor people in need.
How it should work:
You buy a card that's loaded with bitcoins & can only be used by a person in need in a specific hospital or market. My only worry is that this can be abused in some ways, for example, you buy a food card for a person and he/she gets the food and sell it for money. How do we solve this problem?
To be honest, one of the main reasons I don't donate online thesedays is because of misuse of the donations. I want my donations to be used specifically for what they are meant for.
