The present invention provides a weighing apparatus for weighing coins accumulated in a coin hopper using a load cell and automatically taking a periodic readings of the number of coins accumulated in the hopper. By periodically monitoring the hopper and automatically calculating the number of coins in the hopper, theft of coins and other irregularities can be easily and timely detected. The unauthorized removal of coins during an actual or purported maintenance procedure can be detected by automatically determining a count of coins before a hopper access door is opened, automatically counting the number of coins once the door is closed, and using those two counts to determine the change in the number of coins in the hopper at the time of the change. In a preferred embodiment, the identity of the person opening the hopper door and the time in which the hopper door is opened and closed are recorded, along with any detected discrepancy between the change in coin count and an expected change, if any, in coin count. |
