In American business over the past decade, I've experienced an order of magnitude more RFID-detector door locks than keypad door locks. Get your badge/wallet/purse/backpack within a few inches of the detector and you are in.
- vonmoltke 12y agoThat is definitely the trend, because it allows security to give each authorized person a unique access credential, which in turn allows access to be selectively granted or revoked. When I worked in secure environments keypad locks were a pain in the ass, because every time someone's access to an area was revoked the code had to be changed.
- danielweber 12y ago(You could give everyone their own code. 4 digits still allows a few dozen people their own number while still leaving most of the search space open.)
- vonmoltke 12y agoYeah, but that requires giving the locks brains, at which point you might was well just embed an RFID tag in everyone's badge. We had some areas that required both a badge swipe and a PIN.
