ISO/IEC 7816-3:2006规定了集成电路卡和接口设备（如终端）之间的电源和信号结构以及信息交换。 它还包括信号速率、电压水平、电流值、奇偶校验约定、操作程序、传输机制以及与卡的通信。 它不包括信息和说明内容，如发行人和用户的识别、服务和限制、安全功能、日志记录和说明定义。

ISO/IEC 7816-3:2006 specifies the power and signal structures, and information exchange between an integrated circuit card and an interface device such as a terminal. It also covers signal rates, voltage levels, current values, parity convention, operating procedure, transmission mechanisms and communication with the card. It does not cover information and instruction content, such as identification of issuers and users, services and limits, security features, journaling and instruction definitions.
