I’ve been dreaming of doing this ever since I got my Apex. If you can pull it off, I will gladly buy one from you or pay you to modify mine.
There are 2 projects by @StarGate01 that may help you:
- His CTAP-Bridge (I carry around an ACR122U connected to a OrangePi Zero 2W running this to use with my Mac)
- His hack for using the NFC module in Lenovo laptops (It’s Linux only, but it might help you find compatible hardware)
Let me know if I can help in any way or test some stuff for you!
