CA 2354896

A method to activate a vending machine (or any automatic dispenser) by using a random number generator that runs in both the vending machine and a remote computer or similar calculating device running the same random number generator which is remotely located (unlimited distance as no wires or (connected) communication is used between the two [or more] devices). The security of the random number has a serial number factor assigned to each vending machine and a time factor which allows a currently valid random number to expire and become invalid. A time factor allows a limited number of valid random numbers to be active at any time.
