The fact that it’s difficult or expensive to track does not mean it cannot be. Technically it’s possible to force every cash handling business to scan (just like you scan an UPC) each bill.

If I buy you lunch today, you can pay me back next week. We're not "cash handling business[es]", so we wouldn't have to scan.

Second, I don't think it's technically possible. For companies that do business across state lines, sure, but within a state's border, interstate commerce laws don't apply. Each state would have to enact a similar law. And best of luck with that.
