I don't think this is as accurate as you are making out. Wawa (a connivence store in the Philly area) isn't tracking each $10 that goes in and out of the register. It could float all over the city before hitting a bank, and even then banks typically track serial numbers for large demonizations and we when there's a suspicion of illegal activity. Happy to learn more about this if I have it wrong.
