Square for iPhone
Digg’s Kevin Rose is the newest investor in this Square iPhone payment system that we’ve been seeing lately, and as you can see above, he’s demo’ed the unit for everyone over on YouTube. It works as we’ve heard: there’s just an addon that you plug into the iPhone’s headphone jack, and then an app takes information from the swiper, and transmits it out for an actual credit card payment, with a finger doing the signature. The app, as Kevin says, will even upload GPS information, so you can make sure that payments are happening in the right place.
