Aren't most payment systems making a $1 or $0.1 block/charge to confirm the card is real and has non-zero balance? At least that is my experience as an European user, whenever I try to subscribe to anything that came out of the US.

They usually just do an auth request. But otherwise I put $1 just for that case. As long as the balance is normally $0.
