Industries such as health care, laboratories, property management and corporate facilities require vigorous access control to bolster security and protect assets and their workforce.

Here, you’ll discover how ID card access control systems can enhance peace of mind, streamline operations and ease risks.

What are card access control systems?

Card access control systems limit entry to physical spaces using smart cards, biometrics or radio frequency identification (RFID) cards. The system comprises a card reader, an access control panel and software for managing access permissions, logs and alarms.

Key card access control systems are typically installed in commercial, institutional and industrial buildings with high foot and vehicle traffic.

How card access control systems work

Card readers: The card reader is the central point of interaction between the access control system and the user. The user presents their credentials to the reader which conveys the information to the control panel for verification. There are three main types of card readers:

  • Proximity readers detect a card’s presence within a 3-6 inch range by reading a chip embedded in the card.

  • Biometric readers are hybrids that combine card verification with biometric verification, such as fingerprint or facial identification.

  • Magnetic stripe readers are similar to using a credit card at a POS. The user swipes their access card with a magnetic strip that contains access data.

Access control panels are considered the system's central hub. They receive data from multiple entry points and determine if the user’s credentials are valid before granting access. The control panel also records entry and exit data, providing a running log of access events.

Access cards are the credentials the user presents to the card reader to gain access. Depending on the level of security required, access cards come in three common types:

  • Key cards typically contain a magnetic strip that the reader verifies. They are commonly used in hotels and office buildings.

  • Smart cards contain an embedded microchip that can hold more detailed information than a magnetic strip card. They enhance security with features like multi-factor authentication.

  • Radio-frequency identification cards, or RFID cards, use radio waves to communicate with the reader. They are used in hospitals and labs where quick entry is critical.

Software management systems: Card access control systems employ a software management system, an intuitive interface that allows administrators to centrally control all its elements.

Administrators can assign specific access levels to individuals or groups, monitor access events in real-time and generate detailed reports documenting access patterns through the software.

Types of card access control systems

Card access control systems come in different types, each suited for specific access and security needs:

  • Standalone systems: As the name indicates, these systems do not connect to a centralized network and operate independently. The reader stores access permission locally, making them ideal for smaller single-entry applications.

  • Networked systems are common in commercial buildings and multifamily communities. They link multiple entry points to a central control system, allowing administrators to manage permissions, track activity and monitor entry logs in a single platform.

  • Cloud-based card systems allow administrators to use cloud technology for untethered management and system growth. Management can monitor security from any location in real-time.
