I put in an ATM machine for my 5 screen a few years ago in hopes that it would keep us from having to accept credit cards. It didn't. While it helped for a awhile, it wasn't long before we were right back where we started with people walking out the door when they found we didn't accept credit cards. So now we have the ATM machine which does still get quite a bit of use and we accept all major cards. My husband was totally against this move, (one of the few times I did something without his approval), but now even he has agreed that it was the right move. People really do spend more money on plastic than with only cash. They will use their card to buy tickets and then again at the concession stand, where a lot of times they wouldn't even stop at the concession stand or they would stand and try to figure out if they had enough cash for what they wanted.
Mike, don't you have RTS? They make accepting credit cards so easy and seamless, it is totally worth the extra licensing fee. Besides that, it pays off in the good will it generates from the customers. We just fininshed a record year in gift card/certificate sales and a good part of that was put on credit cards. I would much rather take a credit card than a check as you don't know whether a check will clear or not and the credit card money is there in your bank account in the next day or two. My next effort in this is to try and get the system to that clears a check on the spot.

We purchased our ATM machine on a lease/purchase plan from a company called ATM network, thinking it would eventually pay for itself. It didn't and never would have. Like Large said, a lot of people don't want the extra fees that An ATM charges. Our fees are about the norm (I think) at $1.75, but then when the bank adds their fee on, it tends to add up. So my recommendation for what it's worth is to forget the ATM and accept credit cards.
