Re: For Pete's sake
More to the point the key can be stolen. And, I have seen a key card snagged in an elevator door, ripped off the lanyard and fall down into the crack between the elevator and the shaft. Now there is a security issue, a legitimate card at the bottom of the elevator shaft - where it might be stolen by some nefarious and underpaid mechanic and sold to some no-good-nik. The "security" response was to close down both the elevators sharing that shaft to recover the card. That created a traffic jam at the next elevator down the hall, blocked responses to codes and created a gruesome tangle of visitors, patients, and staff, and likely lead to who knows how many unnecessary resistant staph infections. Medical people are often trained to think in terms of triage. In that approach, "security" will inevitably be last.
