PROBLEM TO BE SOLVED: To effectively prevent the occurrence of a trouble such as double extraction by storing only one processing data when duplicate processing data exist. SOLUTION: The data collector for collecting prescribed processed data transmitted from a terminal executing prescribed processing on the basis of an information recording medium for each information recording medium consists of an extraction means for extracting the serial number and processing time of the prescribed processed data from the prescribed processed data transmitted from the terminal, a collation means for collating the extracted serial number and processing time with the serial number and processing time previously stored and extracted in the preceding time and a storage means for abandoning the prescribed processed data received this time when the collated result is in coincidence and storing the prescribed processed data received this time when the collated result is in noncoincidence. |
