ABSTRACT:
An electronic data collection system for managing and controlling information in a restaurant comprises a portable data entry device and an information processing apparatus. The portable data entry device receives data entered by an operator and relays the data to the information processing apparatus by wireless bi-directional communication. The wireless bi-directional communication comprises either a radio communication mode or an electromagnetic induction communication mode. The communication between the portable data entry device and the information processing apparatus is normally effected by the radio communication mode. In the event communication errors occur under the influence of various noises during the communication, the electronic data collection system changes from the radio communication mode to the electromagnetic induction communication mode.
