ABSTRACT:
A meter at each user's house has a bar-coded user number shown thereon, and has a display section for displaying a reading. A data input terminal unit has a bar code reader for reading the user number and a keyboard for manually inputting a present reading. A data recording controller has a meter reading data file having a present reading for each user number. The data input terminal unit radio-transmits a read user number to the data recording controller and radio-receives a previous reading, corresponding to the user number, from said data recording controller. The data input terminal unit computes the amount used from this previous reading and the present reading manually input, and causes a printer to print meter reading data including this used amount on a reading slip while radio-transmitting it to the data recording controller.
