Point of Sale (POS ) Machine
If you operate a retail establishment or other business that handles cash or credit transactions, you probably have cash registers, credit card machines or point-of-sale (POS) machines installed to handle your transactions. Unlike a simple cash register, a POS machine can handle transactions beyond cash and credit sales. A point-of-sale (POS) terminal is a computerized replacement for a cash register. Much more complex than the cash registers of even just a few years ago, the 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. Generally, a POS terminal has as its core a personal computer, which is provided with application-specific programs and I/O devices for the particular environment in which it will serve. A POS system for a restaurant, for example, is likely to have all menu items stored in a database that can be queried for information in a number of ways. POS terminals are used in most industries that have a point of sale such as a service desk, including restaurants, lodging, entertainment, and museums.
Most POS machines look like cash registers and perform many of the same functions. However, POS machines can process check payments, discounts and special offers and other customer transactions. Depending on the setup you select and the nature of your business, a POS machine can also handle inventory adjustments, sales analysis and even office management. POS machines are available for sale or rent to businesses.
