  • Patent number: 4664417
    Abstract: A currency dispenser packet for facilitating the sale of prepackaged foreign currency at a retail outlet includes an envelope containing a preselected quantity of a currency of a foreign country. The envelope is imprinted with a machine-readable code identifying the contents of the envelope as well as the identity of the seller. The code on the envelope is scanned or "read" at the point of sales and the read data is transmitted to a central station processor at which current foreign currency exchange rates are maintained. The processor computes the cost of the foreign currency in U.S. dollars or currency of purchase as well as the applicable commissions and transmits this information to the point-of-sale location. The packet thus allows foreign currency to be sold at locations dealing with travelers such as travel agencies, airline ticket terminals, and other outlets where such sales have heretofore not been practical.
