    • An adaptor card is disclosed that allows a wireless communication device to access and communicate with a SIM card trough an SDIO terminal accessibly located at an exterior of the device. The adaptor card includes a SIM receiving terminal configured to receive a SIM card. The SIM receiving terminal includes a SIM interface that contacts the plurality of pins located on the SIM card in order to communicate with an IC chip located on the SIM card. The adaptor card further includes a signal conversion module that converts signals between a SIM protocol for signals transmitted to, or received from, the SIM card, and an SD protocol for signals transmitted to, or received from, the electronics device. The signal conversion module is also configured to map the signals received at the terminals of the adaptor card to the corresponding terminals of the SIM card.
    • 公开了一种适配器卡,其允许无线通信设备通过可访问地位于设备外部的SDIO终端来访问和与SIM卡通信。 适配器卡包括被配置为接收SIM卡的SIM接收终端。 SIM接收终端包括与位于SIM卡上的多个引脚相接的SIM接口,以便与位于SIM卡上的IC芯片进行通信。 适配器卡还包括一个信号转换模块,该信号转换模块在发送到SIM卡或从SIM卡接收的信号的SIM协议之间转换信号,以及用于发送到或从电子设备接收的信号的SD协议。 信号转换模块还被配置为将在适配器卡的终端处接收到的信号映射到SIM卡的相应终端。
