The Federal Reserve, on or before the July 21st date, announces that the act will become law in its current status with or without adjustment of the safe harbor price of $0.07 or cap of $0.12 per transaction. The current speculation is that networks will implement for Signature Debit, 30 bases points above the prescribed interchange to guarantee the transaction amount.

The Federal Reserve does or does not modify the least cost routing elements of the act.

Net results will be that consumers will be switched from a $0.12 debit card transaction to a blended pre-paid or credit card transaction of $0.60. Therefore, over time, a 20% reduction of debit card usage to pre-paid / credit cards will result in a 100% increase in interchange.
