I haven't commented on the ATMs, I was only replying to the question, not the statement that preceded it. I have owned a retail shop. There are plenty of rules and regulations to worry about, and labor is a massive expense. At no point would I have been inclined to purchase equipment or pay for labor to track serial numbers on bills without a specific mandate to do so. No such mandate exists.
