NCR Corporation

US company and leading provider of automatic teller machines (ATMs), point-of-sale (POS) terminals, and bar code scanners. It was founded as the National Cash Register Company in 1884 in Dayton, Ohio, by John H Patterson (1844–1922), originally as a business manufacturing ‘thief-catchers’ (devices to stop cashiers and sales clerks robbing tills). By 1910, largely due to Patterson's aggressive sales force, his factory was producing 90% of the USA's cash registers. The company changed its name to NCR in 1974 and (following its takeover by AT&T in 1991) to AT&T Global Information Systems in 1994. In 1996 it became NCR Corporation prior to its re-establishment as an independent publicly-traded company.
