PROBLEM TO BE SOLVED: To accurately recognize identification information having many digits including numbers, characters and symbols without increasing an identification body, when the identification body can be identified by identification information according to a resonant frequency of an antenna.SOLUTION: An identification system includes: an electromagnetic radiation part 42 configured to sequentially emit electromagnetic waves of a plurality of frequencies to each of a plurality of information carrying areas included in an identification body; a frequency detection part 43 configured to sequentially detect of resonant frequencies of an antenna according to reflection waves from the antenna to the electromagnetic waves; an individual ID recognition part 45 configured to recognize pieces of first identification information respectively associated with the detected resonant frequencies at an ID database 44; and an ID recognition part 46 configured to recognize second identification information by aligning the recognized pieces of first identification information according to an order that the resonant frequencies associated with the pieces of first identification information are detected at the frequency detection part 43.SELECTED DRAWING: Figure 6 |
