Modern platforms no longer simply secure doors and gates; they now include features like visitor management, workplace activity monitoring, and seamless integration with other technologies. Solutions such as Onfra exemplify this evolution by combining access control with visitor management, desk booking, and self-service kiosks, providing businesses with efficient, accessible, and scalable solutions to fit modern workplace needs.

But what are the different types of access control systems? How do they function across various environments? And what role will they play in the future? In this article, we will explore the types, features, and benefits of access control systems, and how platforms like Onfra are pushing the boundaries of security and workplace efficiency.

What Are Access or Admission Control Systems?

In its simplest form, an access control system is a method used to determine who is permitted to enter or leave a specific area, whether it’s a building, a room, or even a digital system. The main purpose is to ensure security by keeping unauthorized individuals out of sensitive areas or systems.

At the heart of every access control system is the concept of authorization—meaning that only those with the proper credentials can gain entry. These credentials can take many forms, from physical keys and digital access cards to more advanced methods like biometric scanning (fingerprint, facial recognition, etc.). Access control systems are not just about entry; they ensure that different areas or data within an organization are accessible only to those with explicit permission.

Key Components of Access Control Systems

While access or Admission control systems come in various forms, they typically consist of several key components that work together to ensure a smooth and secure process:

  • Authentication Mechanism: This is the process by which an individual proves their identity. It can be as simple as presenting a key or as complex as biometric verification. Common mechanisms include passwords, cards, PINs, and biometric traits (fingerprints, facial scans, etc.).
  • Access Points: These are the physical or digital barriers that restrict access. In physical systems, access points are usually doors, gates, or turnstiles. In digital systems, access points could be networks, servers, or software applications.
  • Management Software: Modern Admission control systems rely on software to manage permissions. This software determines who can access which areas and at what times. For example, a system administrator might give office employees access during business hours but restrict it after hours. Advanced systems, like Onfra, integrate admission control with visitor management and desk booking for a seamless and holistic management experience.

Benefits of Admission Control Systems

Implementing an admission control system provides several key benefits beyond enhanced security. Let’s explore them in more detail:

  1. Enhanced Security
    • The primary benefit of access control systems is security. These systems protect your organization from unauthorized entry, significantly reducing the risks of theft, data breaches, or physical threats. By allowing only pre-approved individuals to access restricted areas or digital resources, access control acts as the first line of defense for your most valuable assets.
  2. Improved Visitor Management
    • Traditional visitor management methods, like manual sign-in sheets, are outdated, inefficient, and often unreliable. Modern solutions like Onfra streamline visitor management by integrating it into the access control system. Visitors can check in via Onfra’s self-service kiosks, which are not only efficient but also accessible to people with disabilities. This automation ensures that visitor data is securely stored and easily retrievable when needed.
  3. Integration with Other Technologies
    • Today’s access control systems can be integrated with a variety of other business technologies. For example, integration with surveillance systems allows for real-time monitoring of access points. Time and attendance tracking tools can ensure that employee hours are logged automatically when they swipe into work. Access control solutions can also connect with HR software and visitor management platforms like Onfra, providing a unified solution that boosts both security and operational efficiency.
  4. Cost-Effectiveness
    • While advanced access control systems may require an initial investment, they can save businesses money in the long run by preventing losses from theft, data breaches, or vandalism. Additionally, these systems reduce the need for physical security personnel, offering a more cost-effective approach to workplace security.

Types of Admission Control Systems

There are several types of admission control systems, each suited to different environments and security requirements. Broadly, they fall into three categories: Physical, Logical, and Electronic access control systems.

1. Physical admission Control

Physical access control refers to restricting access to physical spaces such as buildings or rooms using barriers and guards. Common physical admission control methods include:

A. Lock and Key Systems

  • This is the most basic form of physical admission control, where individuals use traditional keys to unlock doors. While still prevalent in homes and small businesses, lock-and-key systems offer limited flexibility and can be easily compromised if a key is lost or duplicated.

B. Barriers and Turnstiles

  • Commonly used in high-traffic environments such as subways, sports arenas, or office lobbies, turnstiles and barriers serve to funnel individuals through controlled entry points. These systems can be integrated with access cards or biometric scanners for added security.

C. Security Guards

  • Though not a technological solution, security personnel are a form of physical admission control. Guards can manually control who enters or exits an area and are often employed in facilities requiring a high degree of security, such as government buildings or large corporate offices.

2. Logical Access Control

Logical access control refers to securing digital resources such as databases, networks, or software applications. This form of access or admission control manages who can access sensitive digital information based on credentials or permissions.

A. Software-Based Access Control

  • In digital environments, access control software is used to manage user permissions, often based on user roles. This software ensures that only authorized users can access certain files or systems.

B. Role-Based Access Control (RBAC)

  • One of the most widely used forms of logical access control, RBAC assigns access permissions based on an individual’s role within an organization. For example, an IT manager may have access to the company’s server, while a sales employee may only be permitted to access CRM software.

C. Multi-Factor Authentication (MFA)

  • MFA enhances security by requiring users to provide two or more forms of verification to access a system. Common examples include a password and a fingerprint scan. MFA is particularly effective at preventing unauthorized access, even if one credential is compromised.

3. Electronic Access Control

Electronic admission control systems use technology to automate and streamline the process of securing access points. These systems are highly versatile and are used in office buildings, manufacturing plants, educational institutions, and other secured environments.

A. Card-Based Access Control Systems

  • This system involves issuing access cards to employees or visitors, which they swipe or scan at a reader to gain entry.

Types of Access Cards:

  • Proximity Cards: These cards work when held near a reader, making them quick and easy to use.
  • Smart Cards: These cards contain embedded chips that store data, providing a higher level of security than proximity cards.

How Card Systems Work:

  • The user swipes or holds their card near the reader, which communicates with a central database. If the person has the right permissions, the system grants access by unlocking the door.

B. Biometric Access Control Systems

  • Biometric systems authenticate individuals based on unique physical traits such as fingerprints, facial patterns, or irises. Because these traits are difficult to replicate, biometric systems offer a high level of security.

Types of Biometric Scans:

  • Fingerprint Scanning: This is one of the most common forms of biometric access due to its simplicity and accuracy.
  • Facial Recognition: This method uses facial features to verify identity. It is particularly popular in high-security environments.
  • Iris Scanning: Although highly secure, iris scanning is less common due to the cost of the technology.

C. Keypad Entry Systems

  • Keypad systems require users to input a PIN or password to unlock a door. These systems are popular in smaller businesses due to their affordability and simplicity.

D. Mobile Access Control Systems

  • A rapidly growing trend in access control is the use of mobile devices to unlock doors. With mobile access, employees can use their smartphones as access credentials. Mobile systems are particularly convenient as smartphones are a daily necessity for most users.
