A cash till drawer apparatus 100 provides a drawer control signal to a cash till drawer opening mechanism so that the cash till drawer opening mechanism can open a drawer in response to an open signal from an electronic point of sale (EPOS) system. The apparatus comprises processing circuitry U1/U2 configured to, responsive to an open signal from an EPOS system, determine the supply voltage of the EPOS system, derive a drawer control signal from the supply voltage based on the determined supply voltage, and provide the drawer control signal to the cash till drawer opening mechanism so that the cash till drawer opening mechanism can open the drawer. The cash till drawer apparatus allows the cash till drawer to be used with a variety of different EPOS systems. An apparatus and method for monitoring the status of the cash till drawer including counting cash drawer events and a cash drawer unit for receiving a supply voltage form an EPOS and converting the supply voltage to a voltage appropriate to operate the drawer opening mechanism are also disclosed. |
