Method of recognizing whether a transponder of an RFID system is present in a boundary region, RFID system and safety switch

摘要

The present invention relates to a method of recognizing whether a transponder of an RFID system, comprising a reading device and the transponder, is present in a boundary region, wherein a comparison is made with at least one threshold value. In accordance with the invention a bit error rate of signals transmitted between the transponder and the reading device is determined and the at least one threshold value comprises a predefined bit error rate for signals transmitted between the transponder and the reading device. The invention further relates to an RFID system and to a safety switch

1. A method of recognizing whether a transponder of an RFID system, comprising a reading device and the transponder, is present in a boundary region, wherein a comparison is made with at least one threshold value, wherein a bit error rate of signals transmitted between the transponder and the reading device is determined and the at least one threshold value comprises a predefined maximum bit error rate between the signals transmitted between the transponder and the reading device.
