Earlier quoted context omitted.
are you suggesting that the serial number of every note you withdraw is registered against your account?
Modern ATM bill acceptors have sensors that can read serial numbers off of bills. I don't know whether it's been publicly stated that this occurs (and don't have any relevant personal knowledge, either), but the capability exists in the field.
I scarcely use ATMs at this point because they won't hand out "large" bills. Inflation will be the real driver of cashless adoption, as the absurd number of $20 bills (and eventually, $100 bills) you need to pay for anything these days makes using cash too difficult for the average person.
