Create a C/C++ app with the ACR122U (Linux)
Let's now create the application. I will use the C language with the gcc compiler, but it's also compatible in C++ with g++. To communicate with the reader, we are going to use the PC/SC Lite API (WinSCard). All the code is written is a main.c file which is available on GitHub.

On-device WebAuthn and what makes it hard to do well
It's been a few years, but the main references I remember using:
1. Windows: https://github.com/frankmorgner/vsmartcard/tree/master/virtu..., which is a fix-up of the older https://www.codeproject.com/Articles/134010/An-UMDF-Driver-f..., and https://github.com/Watfaq/SoftU2F-Win/tree/master/SoftU2FDri.... Note that neither of these actually implement CTAP2.
2. Linux: There's plenty to refer to on HID gadgets, but https://blog.hansenpartnership.com/webauthn-in-linux-with-a-... and the code at https://git.kernel.org/pub/scm/linux/kernel/git/jejb/fido2-c... were my entrypoint.
3. Mac: I ended up not implementing a Mac version, but GitHub themselves used to support a CTAP1/U2F software authenticator, now archived at https://github.com/github/SoftU2F. I was going to work from that.
For the service I looked at different software "devices" interfacing with these kinds of drivers (or just the browser directly in Firefox's case).
1. Generic NIST SP 800-73 PIV: https://github.com/CCob/PIVert. Very limited scope, pentest tool with no extraneous features. It uses the BixVReader driver.
