Deegitizer

A destructive paper money scanner as a phone dongle, that tops up wallets after scanning and turning the paper bills into ash.

So, you've got dollar bills, and want to pay for something on-line? No problem. Deegitizer is a tiny mobile scanner, that destructively scans bills, and tops up web wallets of choosing.

Implementation -- technically ist quite trivial, because it is much easier to verify money bills, than it is to print them. Basically, combine the money verifier with a thermal heater, or some other way to invalidate paper bills.
