A question I'm wondering is how this works with credit cards... do they offer a credit card payment option? From the article: "...Frierdich tried to hand him $12 in cash, but he directed her to put it in the donation jar." Seems like an opportunity for a new tech that would allow a "customer" to make a credit card donation of an amount they choose. Maybe on exit? Or... idk. Could be an interesting project for someone with a little credit card industry knowledge.
