What a Card Access System Does
A card access system replaces traditional keys with cards, badges, or fobs that staff present to a reader at the door. When the credential is valid, the door unlocks; when it is not, the door stays secured. Instead of issuing and re-keying physical keys, you assign and revoke credentials in software.
Each door gets a reader wired to an electronic lock and a controller. You decide which credentials open which doors and at what times, so a single card can be set to open the front entrance during business hours while staying locked out of restricted areas.
Access Control Bay Area installs and services these systems for offices, commercial buildings, and other facilities throughout the Bay Area, Peninsula, and South Bay.
- Card, badge, and fob credentials in place of physical keys
- Readers paired with electronic locks and a door controller
- Per-person, per-door, and per-schedule access rules
Who Entered and When
Because every card presented at a reader is logged, a card access system keeps a record of who entered which door and at what time. That gives you a clear activity history to review when you need to understand how a space was used.
If a card is lost or an employee leaves, you can deactivate that credential rather than changing locks or collecting keys. New staff can be issued a card and granted only the access they need.
- Entry records showing the credential used and the time
- Deactivate a lost or former-employee card without re-keying
- Grant new credentials with only the access each person needs
Readers and Credentials We Install
