Why would it be virtually impossible for a bank to put an OCR camera on a bill counting machine?

I didn’t mean the state tracking you, I meant the bank doing it so they can sell the data behind the scenes for the usual marketing reasons.

A bank knowing what bills were issued at an ATM is not the same thing as someone being able to tell which vending machine I put it into with good cross indexing to know which bill purchased which thing, as is the case with centralized credit card networks.
