I envisioned that paper currency within the Jackson Republic had a numerical serial number that was readable by OCR and a barcode readable by a scanner. Whenever currency was deposited into a bank it was read by the OCR and scanner after the close of business. Before opening the next morning currency was again read by the readers as outgoing currency. The bills left in the till were re-read and deleted from the outgoing category. This allowed the Republic to combat counterfieting and maintain statistics on a locale's economic flow. If needed the amount of currency in circulation could be adjusted. Every decade the script is replaced to combat counterfieting and hoarding.
