Access control: matching the technology to the door
The best access control system isn't the most advanced one it's the one people actually use correctly.
Access control is about more than who gets in. It's about who gets in where, when, and with what record. Every technology choice is really a decision about one of those four things.
The technology spectrum
Biometrics (fingerprint, face) suit high-security zones where identity matters and people are willing to be identified. Cards and fobs suit most entrances — cheap to issue, easy to revoke. Mobile credentials are increasingly practical for offices. PIN codes suit low-risk, low-traffic doors where simplicity beats security.
Mixing technologies is normal and often correct: a turnstile with cards at the main entrance, biometrics at the server room, a video door phone at the staff gate. What matters is that each door gets the level of control it actually needs.
What people get wrong
The most common mistake is over-specifying one entrance and under-controlling another. The second most common is ignoring the physical reality — a high-security reader on a door that's propped open is a very expensive sticker.
And the most underrated part of access control is administration: who can issue and revoke credentials, and how fast can they do it when someone leaves the company?
