So when you carry more than one card in your wallet, how do you choose which one gets charged? There isn't a good way aroung this without forcing some interface with the customer to make the choice.
I agree with previous posts about signatures being pretty useless. Pin numbers should be implemented and enforced even when running "credit"
If something goes wrong on this ride you're got more serious trouble than any button is going to help you. But of course there is the psychological pacification of just having the button there. Maybe it would make the sheep feel better about their ride.
