Point-of-sale (POS) systems in a loop configuration have included a number of remote terminals and a separate controller for collecting data and supporting terminal operation. For a relatively small system, the controller functions are integrated into one of the terminals, designated a master terminal. The master terminal performs the same point of sale functions as any other terminal in the system, but also includes control and data collection functions.
