It’s too bad that the government does not understand that PIN debit interchange can be negotiated now, between it and a selected network ["New Report Adds Fuel to Interchange Debate"]. Of course, routing priority reciprocation would be required.
Birds do it, bees do it, even folks from Bentonville, AK do it. Why can't Uncle Sam.
