This document specifies the Reader Layer requirements.
The Reader Layer requirements are designed to help software developers of reader/coupler/terminal to manage correctly the Reader Layer.
The present document applies to SAMs, and card applications that can be selected with the selection by DF name as application identifier (AID) defined in ISO/IEC 7816-4. The use of other types of cards in the Reader Layer is possible but is out of the scope of this document.
The Reader Layer is agnostic and must be able to handle different type of cards as well as SAMs in a consistent fashion. Furthermore, it must be able to support any type of reader (contact or contactless) whether the reader follows a standard like PC/SC or offers a proprietary driver. The requirements listed in the present document help to enforce that characteristic of the Reader Layer.
This document does not intend to be exhaustive. Each project may add its own requirements beyond the ones listed in this document.
