What is Access Control & How Access Control Works?

Access control is a security system that allows or restricts entry using authentication methods such as cards, fingerprints, PINs, or mobile apps.

In simple terms, it ensures only authorized people can enter a specific area.

How Access Control Works

Let’s break it down clearly:

1. User Authentication

First, the user provides credentials such as:

• Fingerprint (biometric access control systems)
• RFID card
• PIN via access control keypad

2. Access Control Reader

Next, the access control reader scans the credential and sends data to the system.

3. Access Controller

Then, the access controller acts as the brain. It checks whether the user has permission.

4. Access Control Panel

After that, the access control panel / panels store user data and rules. Therefore, it decides whether to allow or deny access.

Otherwise, the door remains locked.

• Exit button
• No touch exit button
