CLOCK-STOP FREQUENCY ADJUSTMENT FOR A TRANSPONDER

In accordance with a first aspect of the present disclosure, a transponder is provided, comprising: a frequency detector configured to monitor an output frequency of a clock-stop sensor of said transponder, wherein said frequency detector is further configured to determine if said output frequency falls within a response detection frequency range of an external reader; and a frequency shifter configured to shift, in response to the frequency detector determining that the output frequency falls within said response detection frequency range, said output frequency to a value outside said response detection frequency range. In accordance with a second aspect of the present disclosure, a corresponding method of operating a transponder is conceived. In accordance with a third aspect of the present disclosure, a corresponding computer program is provided. 根据本公开的第一方面，提供一种应答器，包括：频率检测器，该频率检测器被配置成监视所述应答器的时钟-停止传感器的输出频率，其中所述频率检测器被另外配置成确定所述输出频率是否处于外部读取器的响应检测频率范围内；以及频移器，该频移器被配置成响应于该频率检测器确定该输出频率处于所述响应检测频率范围内而将所述输出频率移位到所述响应检
