That would assume a comprehensive system of serial number scanning at point-of-sale in order to track the movements and actually connect it with people&#x2F;purchases.<p>The technology is probably available, and it&#x27;s entirely possible that ATMs could be recording serial numbers of dispensed cash and tying them to the account used, but it&#x27;s (presently) deeply unrealistic that every possible (or even most) places that accept paper money have the ability or desire to record serial numbers of incoming &amp; outgoing bills.
