Abstract: A cash register tray includes a base tray having a plurality of change compartments and a plurality of weight sensors, each weight sensor being configured to determine content weight of a respective change compartment. The cash register tray includes a processor in data communication with each weight sensor. Data input and output devices are in data communication with the processor. The processor includes programming for associating each compartment with a respective monetary denomination and monetary value, an initial monetary value and content weight using weight sensor data. The processor includes programming for adding value to respective compartment values if change is added to a compartment as sensed by the input device or weight sensors and for subtracting value from a respective compartment value as indicated by respective weight sensors. The processor divides an increase or decrease by a predetermined value after each transaction to account for coin weight variations.
