I don't know how many of you have heard of "SquareUp" but its a pretty nifty device/software. It basically brings Paypal to you. You sign up for it and they send you a small device to plug into your smart phone. You can then link up to your bank account and begin to swipe cards with the device. There is a 2.75% charge but the rest is deposited into your account. You can add taxes and fees right on your smartphone, send receipts, etc. The app is free, the device is free, and there is no monthly service charge (plus a 0.25% fee reduction from Paypal). This could be used for business or personal reasons, I'll be able to sell things off craigslist using credit cards, sell car parts, yard sales, etc. My brother got his a few days ago and was showing me it so I just ordered mine today. I figured I would let you all know about it if you haven't heard of it yet.
