There is provided a method of recording an image by causing a subject to truly coincide with data relating to the subject. In a finished work recording method using image data by obtaining a product to be recorded and work contents to the product to be recorded as a work recording image, RFID tags(RFID tags) in each of which inherent tag data is recorded are attached to the product to be recorded and to the work recording worker. Thereafter, whether the tag data are true to the image data of a subject to be worked is determined by comparing a time difference between the time at which the tag data recorded in the RFID tagis read and the time at which the image data of the product to be recorded is obtained with a preset specified time. When it is determined that the tag data are truly associated with the image data, the image data associated with the tag data is recorded as a finished work. In contrast, it is determined that the tag data are falsely associated with the image data, the image data and the tag data are discarded.

Image data recording method, method of recording finished work by image data, image data recording apparatus, and finished work recording system using image data

According to an aspect of the present invention, an RFID tag has a long-distance communication RFID and a plurality of short-distance communication RFIDs. The RFID tag has tear-off lines for separating the short-distance communication RFID from the whole RFID tag, and when the short-distance communication RFID is separated, a loop-shaped antenna of the long-distance communication RFID is also cut up. And the RFID tag has an overall management identification code for identifying the whole tag before separation and a partial management identification code for identifying a partial tag after separation.
