Abstract
Abstract An electronic system adapted for recording items to be ordered and to transmit the ordering information in terms of binary coded decimal signals for computer processing at a remote location. The system includes a key operated input device for generating electrical signals and timing signals to be entered into the system. The data signals are stored in a temporary storage register and error checked to determine the identity between the generated signals and the stored signals as well as the operability of the input device and the associated circuits and checked for any operator errors. The correct or corrected data signals are transferred to a permanent storage medium wherein they are recorded on a single track with the data signals and the timing signals alternately and sequentially recorded. The recorded signals may then be converted to audio tones for transmission by a phone to a central receiver.
