How Do Access Card Controllers Work?

Access card controllers function through an integrated system of hardware and software components that manage and secure access to specific areas. Here’s an expanded step-by-step explanation of how these systems operate:

1. Card Presentation

Step Description: The process begins when a user approaches an access point (such as a door) and presents their access card to the reader. This presentation can be done by swiping, tapping, or simply bringing the card close to the reader, depending on the type of card and reader used.

Types of Card Presentation:

• Swipe (Magnetic Stripe Cards): The user swipes the card through a slot in the reader.
• Tap (Proximity and Smart Cards): The user taps or holds the card near the reader.
• Proximity (RFID Cards): The card can be read from a short distance without direct contact.
• Insert (Smart Cards with Chips): The user inserts the card into a slot reader.

2. Data Transmission

Step Description: Once the card is presented, the reader captures the card’s information, which includes a unique identification number or data stored on the card. This information is then transmitted to the control panel.

Transmission Methods:

• Wired Connections: Most commonly, data is sent via wired connections like RS-485 or Ethernet, ensuring reliable and secure communication.
• Wireless Connections: In some systems, especially those with remote access points, data may be transmitted wirelessly.

3. Authentication

Step Description: The control panel receives the data and checks it against a pre-established database of authorized users. This authentication process involves several checks:

• Identity Verification: The system confirms that the card’s unique ID matches an entry in the database.
• Access Rights: The system verifies that the user has permission to access the specific area at the current time.

Authentication Criteria:

• User ID: Matches the card’s ID with the database.
• Time-based Access: Ensures the user is attempting access during allowed times.
• Role-based Access: Checks if the user’s role permits access to the area.

4. Decision Making

Step Description: Based on the results of the authentication process, the control panel makes a decision to grant or deny access. This decision is communicated back to the card reader, which then takes appropriate action.

Actions:

• Grant Access: If authentication is successful, the control panel sends a signal to unlock the door or gate. This signal might also trigger other actions such as turning on lights or deactivating alarms.
• Deny Access: If authentication fails, the control panel instructs the reader to deny access, often accompanied by an alert (e.g., a buzzer or red light) to notify the user.

5. Logging

Step Description: Regardless of the outcome, the system records every access attempt in a log. This log includes details such as the time and date of the attempt, the user ID, the access point, and whether access was granted or denied.

Log Details:

• Timestamp: Date and time of the access attempt.
• User Identification: ID of the cardholder attempting access.
• Access Point: Location or door being accessed.
• Outcome: Whether access was granted or denied.
