masraum, I invented a workaround for this:
1). A bill scanner replaces the DVD drive on buyer's computer.
2). It takes the valuation and numbers off the currency, then sends it electronically as "promissory payment" to seller. (Same as check or CC.)
3). Within two days, buyer takes the same physical currency to a local kiosk and inserts into machine.
4). Machine sends amount to seller's account through electronic banking network.
5). Transaction complete.
there i fixed it
