Guys I own a company and we use an APP on our Iphone called Square for on the road credit card processing. Check up on it. Very legit and excellent ratings. We have never had a problem with them. This is the same program that the Elves are using. This APP doesn't have the ability to save credit card information. I don't think they would take the chance of credit card fraud on top of what is already going on. Just sayin!
Hmm...maybe ey keep the imprint slips & sratch out the imprint with a pen or something. Sounds like fraud waiting to happen. But I guess convenient.
But that's how the infamous NY Confidential got caught up on money laundering charges. They had created a fictional Gotham Steakhouse merchant account for the charges. You'll make more money for the convenience sake, but in the end if you get busted you've just managed to lay own an amazing paper trail.
