My very the high-tech student card has failed me and I was locked out of my room. The card's not functioning anymore. It was still working this afternoon so I have no idea what happened. A guess is that a wire inside the card has disconnected because there are no obvious damages on it.
So what happens if I forget and walk off into the bathroom without leaving the door open? I won't be able to enter my room and would have to call security to open it for me. So far, out of the three of us, Vel and Deng have locked themselves out because they left their cards in their rooms. I'd like to keep it that way :)
But yeah, I have a faulty card.
