I just showed my access card near the door and waited for the beep sound. So what’s wrong with it? Nothing as long as it is in your office. I just did it in front of my apartment door and was wondering why there was no beep sound. My friend got furious: F$*k you idiot, open the door with the key, this is your apartment. Sh!t, this is what happens when you do some real work after a looooooooog time ;-)
