I've seen these in my area for a few years now, one of the local malls has pop and candy machines that take both money and credit cards. I think it's silly to use a credit card for only a $1 purchase, myself. But I do think they can come in handy for more expensive things, like diaper suplies for moms who run out while at a mall or amusment park, or airports so people can buy toiletries (especially these days!). Even snack machines with more elaborate selections (sandwiches and even full entres) could be useful in some locations where it doesn't pay to have a cafeteria or manned snack bar, but people still want/need food.
