PROBLEM TO BE SOLVED: To provide an entrance-exit gate system for controlling entrance-exit by using an inexpensive ticket, and preventing illicit reuse of the ticket. SOLUTION: This gate system controls the entrance-exit to a facility by reading registered data of the ticket, and uses a resonance tag for forming a resonance coil 7c having a specific resonance frequency as an identification element of the ticket 7. A gate body 1 of an entrance-exit gate is equipped with a gate door 2, a reading antenna 3 of the resonance tag attached to the ticket, a breaking device 4 of the resonance tag for annuling the function of the resonance coil by an induced current, and a control part 5, and allows the passage of a user carrying the ticket by opening the gate door after breaking the resonance tag when the ticket is normal on the basis of a reading determining result of the resonance tag attached to the ticket. |
