That's interesting.
I just throw this out to all of you, and if any of you have any information on this, it would be very helpful for me. Are you aware of any studies that have ever been done with a control group of people who use just cash, say, versus a group that uses the new technology? If they've been given the same amount of money, who would spend that money more quickly, the people with the cash or the people with the mobile payment?
