My old system for credit card processing used a cell phone but it
was analog. Few places have good analog service anymore and it
costs lots now if you can get it at all.
My setup was this:
Trans330 connected to a “computer interface” connected to cell
phone. The interface came from motorola and makes the Trans330
think it has a dial tone. You also have to deal with the power
issues - the Trans330 runs off an adapter that makes an unusual
voltage dc current so you need a battery pack, a dc to ac converter,
then the Trans330 adapter. The cell phone has to match the computer
interface, and the cables to do so are not the easiest to find. If
you want to do this, I have some old equipment that I am more than
willing to part with.20
What I do now is to use a Nurit3010. It has all the stuff, swiper
and packetized secure digital cellular, in one box and runs off an
internal rechargable battery and doesn’t require the brain damage
described above. I use First Data as well and it works just fine.
There are less expensive credit card systems that swipe the card,
remember it and download the info to the processor over conventional
phone lines. I chose the Nurit 3010 because I want to know that the
credit card is valid before the client leaves with my stuff.
Good luck, this problem can make your head hurt.
