SM Cinemas, the biggest chain of movie theaters, have a membership card. It is like an ATM card that you can load with cash. When buying ticket, the card is swiped to deduct the amount of the ticket. In that counter, you can also add a load to your card so you will not bother next time. The beauty of the card aside from the convenience of not paying with cash is the automatic discount they give to card holder. I find that theater membership card very beneficial for regular movie goers.
