Figure 1-1 A typical IT environment for a department store

IBM POS systems are very much like standard Intel®-based workstations. There is a motherboard with an Intel x86 processor, memory, graphics adapter and network interface card. In addition there is also one or more USB interfaces. However, there are also some diferences: A POS system typically has several peripheral devices attached, including but not limited to;

￿A keyboard, specifically designed for the point-of-sale system

￿A touch screen

￿A barcode scanner

￿A scale

￿A sensor (to verify the customer puts the item in the bag)

￿A credit-card reader with signature type pad or pin code keyboard

￿A cash-drawer

￿A printer for receipts
