    • A system and method for contactless data transmission. A transponder includes a reception unit for receiving a modulated RF signal, a signal processing unit which is connected downstream of the reception unit and a unit for processing at least two differently modulated and/or coded RF signals, for providing a supply voltage and for providing a data signal produced from the modulated RF signal, and a data processing unit which can be connected to the supply voltage and to which the data signal can be supplied, and which is connected to the signal processing unit for setting the modulation type and/or coding type for the RF signals to be processed. The signal processing unit is set to the process differently modulated and/or coded RF signals in chronological order, starting from application of a supply voltage until the data processing unit identifies reception of a prescribed data signal.
    • 一种用于非接触式数据传输的系统和方法。 应答器包括接收调制RF信号的接收单元,连接在接收单元下游的信号处理单元和用于处理至少两个不同调制和/或编码的RF信号的单元,用于提供电源电压并提供 由调制的RF信号产生的数据信号,以及数据处理单元,该数据处理单元可以连接到电源电压并且可以提供数据信号,并且连接到信号处理单元,用于设置调制类型和/或 要处理的RF信号的编码类型。 信号处理单元从施加电源电压开始到数据处理单元识别规定的数据信号的接收之前,按时间顺序将RF信号设置为不同的调制和/或编码的RF信号。
