Technically the same I guess, you just have to refill it regularly ;-)

But debit cards doesn't necessary need to be linked to a bank either. Today you can have a crypto debit card and pay with say Cardano. It's like what people back in the old days would refer to as a bank of their dreams, i.e savings account with +5% interest, you're in full control, full privacy, and "backed by gold"* as in Cardano is market valued, just like gold so you won't suffer from permanent inflation, value can both go up and down, but generally goes up over time.

In America that's called a "gift card", typically bought when you don't know exactly what someone wants but you know where they can get some cool stuff they'd like.
