A computerized method for detecting the under ringing and sliding of merchandise by a cashier in an electronic cash register system employing a plurality of electronic cash registers and a cashier at each cash register, said cash register system compiling raw cash register data which includes the total number of items and dollar amount for all items sold by each cashier for each cashier day the cashier works, said method comprising:

  • providing a computer;

    inputting and storing said cash register data into computer-readable memory;

    processing said cash register data on said computer to determine a cashier average item price for each cashier which represents the average price of the items sold by a respective cashier on each day;

    indexing said cashier average item price to a respective cashier and storing said cashier average item price for all of said cashiers in a cashier database in a computer-readable medium;

    processing said cash register data to determine the store average item price representing the average price of all said items sold by all the cashiers during a specified time period;

    comparing said daily cashier average item price and said store average item price to determine the daily deviation of each said cashier from said store average item price;

    computing a cashier deviation for each cashier by algebraically summing said daily deviations of each said cashier; and

    determining if said cashier deviation of an individual cashier is significantly different from the cashier deviation of the other cashiers so that said individual cashier can be identified for further investigation.
