OK. The fact the barrier opens for you but your passage isn't logged is just *insane*. Either the damn system saw a valid card and identified it, or it didn't. If it didn't, then it shouldn't be opening the barrier.
So it seems that that the means of identifying the individual card doesn't have anything like enough data redundancy/deliberately-illegal-permutations built in, and was resonding to a valid identity code that was not your own.
Either that or the system is so ridiculously badly designed that the barrier-opening & passage-logging actions are each triggered off completely separate sensors.
