Renting from hasting's will someone else's hasting's card

So I rented a game from Hastings, which is $7 for a rental period of a week. I paid in cash and then used my ex's hastings card when the cashier asked for one. Can I not just keep the game now? Will they charge the rental fee to him? Please don't go on about me being a bad person, my ex is a dick.
