The controller verifies the user’s identity against the database and grants access if they are allowed in that area. Then, when someone swipes or brings their card close enough to the scanner, it captures the information and sends it to the controller for verification. The key card is programmed with an individual’s details so key card readers can identify them. Today’s key card door entry security systems generally rely on RFID access or magnetic stripe technology, allowing users to tap, swipe or use proximity to a key card machine to access a secured area. How does a key card access solution work?

Access card systems software: Key card door access systems require software to store user data, manage access rights and monitor system activity.

Multi-factor authentication ( MFA) devices: Some key card entry systems require users to enter a PIN code in addition to swiping their electronic card for added security.

A card key door lock can be triggered manually or automatically, depending on the type of access card system for doors being used.

Electronic key card door lock: Card key locks are mechanisms that lock or unlock the door when a valid key card is swiped.

Controller: The main unit of the key card access system, the controller sends commands to open or close doors as needed by communicating with the user database.

Key card scanner: A card reader security device installed on doors and gates that reads the information stored on electronic card keys.

Door key cards: These are security cards for doors with embedded chips that store information about the user’s identity.

Components of card access control systemsĬard access security systems consist of several different components:

The key card door lock system will permit or deny access based on the access privileges assigned to the cardholder. This door card access system operates by verifying the information stored on the key card through the security card reader.

What is a key card system for access control?Ī key card access solution is a combination of card credentials, door card readers and locks that limit access to a building or space.
