New York Times : A Simple Swipe on a Phone, and You’re Paid

"It’s always thrilling when somebody looks at the Way Things Have Always Been Done, and then asks: Why?
And then goes on to change the world forever.
1967: Why is it necessary to wait in line for a human teller if all you want to do is withdraw cash?
1974: Why shouldn’t your document on the computer screen look the same way it will when it’s printed?
1991: If shampoo always settles to the bottom of the bottle, why is the cap on top?" ~David Pogue

I have to say that this intrigues me. I do some computer work on the side and being able to do this would make life a bit easier. Of course I would have to get the phone and hardware to do this but I digress. I can honestly say that I see a downside right away though, being from service industry jobs for a long period of time, what if the person reverses the charges on you. Or where does the money go? But the ammount of money the company asks for is fairly reasonable for the use of this device.
