ISO/IEC 7816-6:2016直接或通过引用规定了数据元素，包括可用于行业间交换的复合数据元素。 它确定了每个数据元素的以下特征: -标识符； -姓名； -描述和参考； -格式和编码（如果在其他ISO标准或ISO/IEC 7816部分中不可用）。 每个数据元素的布局如接口设备和卡之间的接口所示。 它提供了数据元素的定义，而不考虑对数据元素使用的任何限制。 它不包括卡内和/或外部世界的内部实现。 除登录数据对象（6.5）外，ISO/IEC 7816-6:2016中仅适用于应用程序类标签。 当使用跨行业模板时，允许应用程序在该模板下嵌套特定于上下文的类别标记（见ISO/IEC 7816-4），除非之前标记为保留供将来使用ISO/IEC JTC 1/SC 17。

ISO/IEC 7816-6:2016 specifies directly or by reference, data elements, including composite data elements that may be used in interindustry interchange. It identifies the following characteristics of each data element: - identifier; - name; - description and reference; - format and coding (if not available in other ISO standards or parts of ISO/IEC 7816). The layout of each data element is described as seen at the interface between the interface device and the card. It provides the definition of data elements without consideration of any restrictions on the usage of the data elements. It does not cover the internal implementation within the card and/or the outside world. With the exception of login data objects (6.5), only application class tags are eligible in ISO/IEC 7816-6:2016. When using an interindustry template, an application is allowed to nest context-specific class tags (see ISO/IEC 7816？4) under such a template unless it is previously marked as Reserved for Future Use ISO/IEC JTC 1/SC 17.
