According to our research an estimated 17% of stock loss in retail happens at the checkout – at the hands of staff.
Tricks used include:

• After scanning a product and handing it to the customer – who is a friend of the cashier - the line item is voided and the product is basically stolen

• Likewise for friends a cut price is entered via manual input

• Receipts are cancelled midway through the checkout process, but the goods are handed to accomplices

• Faking cash outs for returned products that do not exist

In the past these deceptive attempts were seldom discovered. And if they were it was mostly due to either complex controls, test purchases, hidden cameras or plain coincidence.

The answer is there, but it has a price

Modern data mining software increases the detection ratio of this kind of fraud, as all data generated at the checkout is processed and systematically analysed.
Usually however a substantial investment is necessary, since software and hardware must be bought, adapted and integrated by specialists and loss prevention managers must be trained for proper utilization.
