Those people lack education on the topic.
I remarked there's a reason why the key cards are unmarked, right?
It isn't just individuals who can't into OPSEC though. Soon after this conversation, the company created a policy saying you have to pay $10 to get a new key card if you lose your key card.
I thought that was stupid. Now, suddenly you have incentivized people to NOT report they don't have possession of their key card any more. We want people to report the instant they lose access to their key card, not three days later when they have exhausted all options. My understanding is that you can easily reactivate a key card if it is found again and the risk of unreported lost cards outweighs the cost of a new key card.
I also agree with the conclusion (the risk of unreported lost cards outweighs the cost of a new key card).
