NFC → PC/SC Bridge for AusweisApp eID

Status: WORKING — AusweisApp detects and reads eID card via custom PC/SC IFD handler

Overview

A custom pcscd IFD handler (ifd-nfc.so) that bridges the Linux kernel NFC subsystem (AF_NETLINK + AF_NFC) to the PC/SC smart card API. The only other known implementation with this architecture is jurajsarinay/ifdnlnfc (2024, GPLv2, experimental), which lacks 10+ critical robustness fixes we discovered

For Building

• Visual Studio Build Tools https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2022 -> Check the C++ Development profile and install. (Or Install Visual Studio Express)
• Git https://git-scm.com/install/windows
• Vulkan SDK https://vulkan.lunarg.com/sdk/home (full SDK highly recommended)
• winget install Ninja-build.Ninja -> Ninja is part of the build files but not in PATH etc. so it's a pain to try to use that one. could also use another generator but I like ninja.
• winget install Python.Python.3.14

Optional
