Point of sale (POS) (also sometimes referred to as Point of purchase (POP) ) or checkout is the location where a transaction occurs. A "checkout" refers to a POS terminal or more generally to the hardware and software used for checkouts, the equivalent of an electronic cash register.
A POS terminal manages the selling process by a salesperson accessible interface. The same system allows the creation and printing of the receipt.
