Me too!

Maybe we could setup a system where folks get a coupon with a unique key, as follows:
Make kiosks with 2 buttons: Buy voucher, and Valitate voucher (or whatever it's called).
Gift buyer pays a special kiosk a certain amount, and receives a transfer-only voucher with a unique key (the voucher represents the amount paid). Money goes into a central account (we already have something like this for donation kiosks, yes?) Gives it as a present to something else.
Something else validates the voucher, it's recognized for the amount that it's worth, and that amount is payed to them. They can then buy something.
Is something like this doable?
