An apparatus for fixing RFID tags fixes a RFID circuit element on a print label to produce a RFID label. At this time, a barcode provided on the print label side is read by a barcode sensor, and information to be written corresponding to barcode information is written into the RFID circuit element through an antenna via wireless communication. The barcode on the print label is associated with the label print, whereby a RFID label with print can be produced in which the label print and the information to be stored in the RFID circuit element are associated with each other.
