In a method for operating an anti-theft system and an anti-theft system operating according to the method, a stationary transceiver sends a question code signal to a portable transponder, which in turn responds with an answer code signal. The answer code signal is scanned at predetermined scanning times and a piece of code information is demodulated therefrom. If the first bits of the answer code signal are already unreadable, then the scanning time is displaced by a phase angle, and the remainder of the answer code signal is read. |
