  Electronic Credentials:

  n

  n
  nThese can be key cards, key fobs, biometric data (fingerprint, facial recognition), PIN codes, or even mobile credentials like smartphone apps.

  Controllers:

  n

  n
  nThe “brain” of the system, the controller receives the credential information from the reader, verifies it against a database, and determines whether to grant or deny access.

  Locking Mechanisms:

  n

  n
  nThese can be electric strikes, magnetic locks, or electrified crash bars that are activated by the controller to physically secure or release the door.

How it Works:

n
1. n
   n

   n

   n

   1. Authentication:

   n

   n
   nWhen a person approaches a door, they present their credentials to the reader (e.g., swiping a card).

   2. Verification:

   n

   n
   nThe reader transmits the credential information to the controller.

   3. Decision:

   n

   n
   nThe controller compares the presented credential against its database of authorized users.

   4. Action:

   n

   n
   nIf the credential is valid, the controller activates the locking mechanism to unlock the door, allowing access. If invalid, the door remains locked.

   5. Logging:

   n

   n
   nThe system typically logs every access attempt, whether successful or not, providing valuable data for security monitoring and reporting.
