I have been interested in using a card reader (through self-written applications) for some time. And I have accumulated during this time a collection of chip card relevant documentation: Specifications, API documentation and so on.
I have packaged (some of) this stuff into several ZIP archives and uploaded them into the Files section of this project.
See the content of the README.md
file there, which is nicely displayed at the bottom of the file manager page for the directory.
