I just got off the Victory and I used my sail and sign card, because I didn't want to carry around a credit card too. You can use any card with a magnetic strip.
I did make the mistake of locking the safe with one sail and sign card then trying to open with my boyfriends by mistake. It makes the safe unopenable and maintenance had to come and open it. This was NOT included in the safe instructions so be careful to remember exactly which one you used to open it.
Other cards can be used, like your drivers licence or ATM card, so I imagine the AAA card would also work.
