Communications Conveyor Company “Comco” was formed in 1968 by Harold Greene, who holds 11 patents, primarily in pneumatics. The company ultimately entered the bank drive-thru business, distributing products through a national network of value-added resellers.  Unique features of Harold’s design was the remote placement of the blowers.  Blowers with powerful suction, and very little noise.  This innovation, backed by very high quality and reliability, built a very solid business that is still with us today.  



Harold’s daughter, Melissa, married a young man named David Carder. David began working for Comco, literally starting from the shipping platform and working his way up to the leadership of the company. In 1999, Harold and David formed Comco Direct, Inc., to serve as a direct source of banking equipment and services to the Texas market. Comco Systems continued to sell wholesale through the rest of the U.S., and a limited international market in Central America.
