CA 1053372

Abstract of the Disclosure: A piece of scrip with groups of patterns can be sensed by a validator. One group of patterns will define a code which will permit that piece of scrip to be accepted only by validators which have that same code stored therein. Two additional groups of patterns define codes which can cause those scrip validators to actuate price-determining relays within a vending machine. Each pattern is formed by spaced parallel lines, and various patterns can be given different identities merely by changing the spacing between the trailing edges of those spaced parallel lines. The patterns in each group of patterns will be sensed in a prescribed sequence, and the sequentially- sensed patterns in any of those groups of patterns can be given various identities. As a result, per- mutations, rather than mere combinations, of potentially-usable pattern identities can be used. The scrip validator stores the codes, which correspond to the codes defined by the patterns in serially-shifted shift registers; and the data within the shift registers is serially shifted a plurality of times.
