Title: Tallying method and means

Abstract: A secure tally method and means is provided for tallying events such as dispensing of product and receipt of coins by a vending machine. These events are made to initiate a signal in a signal generator. The number of those signals is recorded in a counter which is physically removeable from the signal generator and which must be removed to determine what count is stored. The counter is one that has a maximum counting capacity either by its construction or pre-loading. To read it, one adds counts until the capacity of the counter is reached. Subtracting the added counts from the counter's maximum capacity determines the number of counts that were entered as a result of the occurrence of the events being counted. When the event is the receipt of coins, the system is extended to compute value received by generating and counting signals in an amount corresponding to the value of the coins.
