The point of sale (POS) terminal is a crucial system in any retail business operation. This computerised setup is designed to replace the traditional and out-dated cash register. In simple terms, the POS will calculate the payment owed by the customer and present an electronic or printed receipt. In addition, this product is often used in handling the inventory, processing cash cards and tracking customer orders. Regardless of the scope of your company's POS functions, it is important to secure this system against potential infiltration.
