To improve the precision of input data by allowing a mobile terminal device to accurately recognize a measuring place and read measuring meter at the place, and inputting the data to the mobile terminal device.
A person in charge of measurement while looking at a map of a measuring place indicated in an operation instruction book, etc., carries the mobile terminal device 1 and searches for the measuring place to find a measuring meter 5, and then reads an identification mark recording body 4. This identification mark recording body 4 allows the mobile terminal device 1 to recognize from which measuring place a data value to be inputted comes, make it correspond, gather and transfer data to a general computer terminal 2. Then the general computer 3 performs a specific process on the basis of the transferred data. Consequently, the person in charge of measurement needs to pay attention to only the correct input of a numeral and the influence of the skillfulness of the person in charge is reducible.
