发明名称 Resistive evaluation of the coupling factor of an electromagnetic transponder
摘要 A method for evaluating the current coupling factor between an electromagnetic transponder and a terminal, wherein a ratio between data, representative of a voltage across an oscillating circuit of the transponder and obtained for two values of the resistive load, is compared with one or several thresholds.
