>The problem is fraud + disputes

Banks pay fees today around this to the payment networks. The Fed could simply charge a tiny fee per transaction to the bank to cover this.

It would be much less expensive than Visa and Mastercard, since there is no service fee on top.

To clarify, I never said it be 100% free, but it would dramatically lower and standardize fees.

As far as trust goes, if you can't trust the central bank, we have bigger problems don't we?
