I'm looking for a payment system that is able to accept credit cards so that I can sell game codes. I've done it in the past with paypal, but basically anyone can chargeback and win. I usually shipped a piece of paper with the codes so I beat most disputes but it's very annoying. Anyone have any experience with any other cc accepting services that don't allow chargebacks or offer digital product protection? ps: I searched around but found nothing too solid.
