Abstract
A POS system comprises a checkout means for carrying out a payment operation, a cash drawer which includes a storage compartment for storing money, wherein in an open condition of the cash drawer the storage compartment is open for an access and in a closed condition of the cash drawer the storage compartment is closed, a control means for controlling the cash drawer, wherein the control means is formed to generate a control signal for opening the cash drawer, and a sensor means for generating an opening signal which indicates whether the cash drawer is in its open condition. The control means is formed to evaluate whether or not an opening signal is preceded by a control signal with a predetermined time interval, in order to detect a manipulation process during opening and/or closing the cash drawer on the basis of the evaluation.
