One problem with this discussion is while nice; it's an example of the tail trying to wag the dog. The needs of transit authorities to be able to collect small payments rapidly probably is not high on the list of lawmakers' concerns, especially since in the US the jurisdictions running transit agency are not those printing and coining money.

The better solution is to move to electronic fare collection systems (RFID-based, smartcard-based, whatever) for most trips. For one-off trips by non-regular transit users; onboard (or platform-located) vending machines can sell single-ride tickets.

At a very minimum, transit authorities who have little cash to upgrade their onboard equipment, could still switch to a proof of payment system (enabling faster boarding and rear-boarding) by having the driver give out transfers for all cash fares; anybody with a pass or a ticket purchased elsewhere is free to use the rear door; anyone who wants to do it the old fashioned way has to board in the front, pay exact change, and keep their receipt.

This will help transit agencies run efficient operations more than hoping the greenback goes away; even if the US currency is excessively paper-based..wllv20111108
