The NCR Corporation (formerly National Cash Register) is a computer hardware, software and electronics company that provides products and services that enable businesses to connect, interact and transact with their customers. Its main products are self-service kiosks, point-of-sale terminals, automated teller machines, check processing systems, barcode scanners, and business consumables. They also provide IT maintenance support services. NCR had been based in Dayton, Ohio, starting in 1884, but in June 2009, the company sold most of the Dayton properties and moved its headquarters to Metro Atlanta. Currently the headquarters are in unincorporated Gwinnett County, Georgia, near Duluth.

     NCR was founded in 1884 and acquired by AT&T in 1991. A restructuring of AT&T in 1996 led to NCR's re-establishment on 1 January 1997 as a separate company, and involved the spin-off of Lucent Technologies from AT&T. NCR is the only AT&T spin-off company that has retained its original name—all the others have either been purchased or renamed following subsequent mergers.

     One of the main reasons NCR left Dayton was due to state tax infrastructures between Ohio and Georgia.  Georgia's tax laws are more lax than Ohio's and this ultimately led to NCR leaving.  As of 2013, NCR had a total value of $8 billion.
