ABSTRACT:
A method of electronic payment comprising: providing a memory with an EPROM counter and a pointer; inserting the memory into a machine; decrementing the counter in steps which correspond to a unit of payment, in an irreversible manner, until the counter is equal to the pointer; stopping the decrementing; and incrementing the pointer, without removing the memory from the machine, when a gain is achieved in response to a random external event.
