Abstract

A device for the identification of information, particularly an access control system consisting of electronic lock and key portions in which, when the key portion approaches the lock portion the oscillator circuit of the lock portion oscillates at high frequency, this oscillation being picked up by the key portion and, modulated by a frequency or pulse pattern that serves as a key identifier, retransmitted to the lock portion to be further processed by the lock-side receiver and recognition device. The transmission and retransmission of the energy between the lock and key portions is effected by a wave coupling by means of antenna coils, this producing an inductively coupled synchronisation switch, this causing a changed signal curve caused, for example, by a more or less complete short circuit at the key-side coil or by an energy impression on this.
