Method for enabling authenticated access of an individual to a security area and security system for implementing the method
First Claim
1. A method for enabling authenticated access of an individual to a security area by means of a transponder carried by the individual which on receiving an interrogation signal outputs an ID code group, and a control unit located in the security area which generates the interrogation signal and checks the ID code group output by the transponder for enabling access of the individual to the security area only when right of access is authenticated, characterized in that said interrogation signal is relayed by capacitive coupling from said control unit (18) via said individual (10) to said transponder.

Abstract
A method for enabling authenticated access of an individual (10) to a security area (12) by means of a transponder (14) carried by the individual which on receiving an interrogation signal outputs an ID code group, and a control unit (18) located in the security area (12) which generates the interrogation signal and checks the ID code group output by the transponder (14) for enabling access of the individual (10) to the security area (12) only when right of access is authenticated, is characterized in that the interrogation signal is relayed by capactive coupling from the control unit (18) via the individual (10) to the transponder (14).
