Abstract

A data transfer and communication system is disclosed including a central station and a plurality of remote, relay terminals. Each relay terminal includes a data entry device such as a keypad or bar code wand. A headset is associated with each relay terminal. Circuitry is provided to permit two-way wireless communication between the headset, relay terminal and central station. The relay terminal functions to transmit substantially unprocessed voice and data signals to the central station. The central station analyzes the signals and can retransmit a response which can be displayed on the relay terminal. The relay terminals are intended to be high volume, low cost items with the more expensive computational power being located at the central station.
