I thought the concept of a credit card was that you didn't have a positive amount
it's not a bank account; you don't pay 500 in and then take it all out later, that's a debit account. If it's a credit card, your balance is between 0 and -100.

Or have I, in my heady world of international finance, completely misunderstood the word "credit" in this situation?

I always thought it odd that credit cards only go in debit,
and if you want to go into credit, you have to get a debit card.
