It's a safe that takes normal debit/credit cards, you just have to assign your card to it and the card will work like a key alongside a password combination. The toy does come with its own card so that you can use it if you don't own a regular bank one. Most kids surely wouldn't, but considering that this was released in the 80's Japan even most adults didn't have them yet. Cash transactions were always favored in the country and to this day remain more mainstream than in the west, so the gimmick was pretty ahead of its time.
