Summary:A smart card inlay includes an inductive antenna and a DC-DC converter. The inductive antenna is configured to (i) wirelessly communicate with the card terminal, and (ii) power the card circuit via inductive coupling with the card terminal. The DC-DC converter has an input coupled to the inductive antenna and an output connectable to the card circuit. The DC-DC converter is configured to receive an input power signal from the inductive antenna and to convert the input power signal into an output power signal for transmission to the card circuit, the output power signal being matched to an operating current and/or an operating voltage of the card circuit. 一种智能卡嵌体包括感应天线和DC-DC转换器。感应天线被配置为(i)以无线方式与卡终端通信，和(ii)经与卡终端的感应耦合为卡电路供电。DC-DC转换器具有耦合到感应天线的输入和能连接到卡电路的输出。DC-DC转换器被配置为从感应天线接收输入功率信号并且将该输入功率信号转换成输出功率信号以发送给卡电路，所述输出功率信号与卡电路的操作电流和/或操作电压匹配。
