Implement RFID Auth

[noqqe]

Write Bearer Token from backend to RFID Card

Needed:

• Increase valid time for Bearer Tokens to 2 Years or so.
• RFID Writer

Do we have appropriate RFID reader/write hardware? IIRC I left mine for exactly that purpose?

[noqqe]

Yep, we still have the hardware.

I was basically not able to properly use pynfc or nfcpy and failed getting the connection to the device.

Being desperate, I was trying to recompile the binary blob that was used in the past at k4cg/matomat using libnfc from the debian repos and later doing an exec to this. But same here, failed with build errors.

Would need some help here.

However, implementation of the Auth would be different. A sketch was already done here: https://github.com/k4cg/matomat-service#what-about-rfidnfc-chip-based-login

Yes I read the part about auth in server, sounds nice!

Somebody on the mailinglist was volunteering to get this working for CCCamp.
Maybe he tried something else.

Seems like @chca42 is working on it ;)

[chca42]

Yes, I'm currently working on this with good progress ;-)
I have built a python module for reading and writing cards. The JWT Token can already be written, auth and retrieval is work in progress.

I have not seen the feature in action, but what is the state of this issue?
Can it be closed?

[chca42]

NFC Auth is now implemented and deployed on matomat.
