[sudo-access] Door Card Reader Issues

Hey all, I just talked to Tavio from Phat Beets, he had a few cards that did not seem to be working. I tested all three and got unreliable results. I got every combination of both light (green blink, green solid, red blink) and failure / success of opening latch. Especially of note, is that one card of a type I'm fairly certain does not work correctly, when swiped incorrectly, creates a red light, but also successfully opens the latch. This gives me the impression that an error code (rather than a card's unique code) has been incorrectly added to the whitelist! And overall, swiping is incredibly inconsistent even for my own card, which I know to have worked well for a long time. I'm going to buy at least one usb magnetic card reader right now, please join me in fixing this system so it works consistently, reliably, and securely ASAP. // Matt
