But if I understand you correctly, what I’d have to do is actually change my app password/lpc login/whatever to match the chips UID? Is that right?

That’s correct

Login with a serial RFID / NFC reader under Windows and Linux

As a have a few RS232 and Wiegand readers on order and I intend to use them to log into my personal and work computers (login, screensaver unlocking and general PAM authentication under Linux), I decided to prepare my machines to handle those readers. I figured this might be of interested to some of you also. Serial readers are “dumb” in the sense that, unlike PC/SC or CCID readers, they only report the UIDs of whatever chip they happen to be able to read. You can’t use them to do anything smar…

Well, just to let you know, I used the long Easter weekend to do a much needed code cleanup - and I added a few of functionalities too. I’ve renamed the project SiRFIDaL - Simple RFID authentication for Linux. It’s not a terribly clever name, but then I’m not a very imaginative guy. At least it says what it does. Also, nobody else was using it …
