Just received my square point-of-sale card reader and did a test purchase with myself. Holy Crap! This is awesome. Simple, Sleek, Easy. You can itemize purchase items (with a photo per item, if you want), add a tip, send a reciept to the buyer via email. The buyer swipes their card and signs on the screen and you're done. https://squareup.com/
It's 1000x more useful and immediate then paypal while being cheaper too.. 2.75% fee + 15 cents per card swipe vs. Paypal's almost 7% fee.
