A point-of-sale (POS) terminal is a computerized replacement for a cash register, although much more complex than the cash registers of years past. A POS system can include the ability to record and track customer orders, process credit and debit cards, connect to other systems in a network, and manage inventory. A POS terminal has as its core a specialized microprocessor, which is provided with application-specific programs and I/O devices for the particular environment in which it will serve. POS terminals are also increasingly web-enabled, which makes remote training and operation possible, as well as inventory tracking across geographically-dispersed locations. POS terminals are used in most industries that have a point of sale such as a service desk, including restaurants, lodging, entertainment, and museums.
