nsa digital cash?

i doubt it will be long before there are some official government agencies developing the official u.s. digital cash system.

This statement betrays an enormous ignorance at the scale of Federal involvement in retail transaction systems. The Fed operates Fedwire, for moving federal funds around, and also does check clearing at the national level. All the retail level transaction systems are in private hands, be they ATM networks and consortia or the credit card companies. Eric
