Retail Technology Limited, or RTL for short, does what it says on the box: technology for retailers. The company is a result of a merger between two businesses in June 1999, CyberTactics and Viking Systems, which were both providing services to branded shoe retailers and two major shoe suppliers (Clarks & Start-rite). From there the company has grown to become a leading player with retailers and supplier alike in providing innovative yet solid IT solutions. RTL not only sells, configures, installs, trains and supports full EPoS and stock management systems but also exchanges data between the two. You can read more on this here.
