Tom I'm getting an I phone this week just for squareup, I may not get an I phone, but I'm going to get one that's compatible with Square. I have a nice unit at the shop, but it's a pain to have to key in transactions when I get back to the shop if I write hard copies, They said my VeriFone card terminal can be set to swipe and store when at shows, but you don't know if the card is good or stolen, and won't until you plug in and run a batch. the Squareup is the way to go and I can't wait.
