 |  Access Control

There are numerous options available when it comes to securing a business and its assets. Depending on your needs, budget, and risk factors, a wide array of access control systems can be implemented. Each has its benefits, drawbacks, and usage scenarios. The access control system is the electronic system that controls access to secure locations or resources. Also known as entry control or ID systems, users can gain entry to secured areas or locked rooms by presenting an authorized digital credential or ID token when requesting access. There are several types of access control systems commonly used for commercial businesses. Some are more effective in certain situations than others; each has advantages and disadvantages. Let’s look at some of the most common ones you may want to consider if you’re exploring entry control solutions for your company.

Card Access Control Systems

A card-based access control (also called a card-based ID system) system is a hardware and software solution that uses a physical access card or token to grant authorized personnel access to controlled locations, rooms, or buildings. These can be employed in a variety of industries. These systems are pervasive in commercial office buildings and industrial facilities. A card access control system consists of an electronic lock connected to a control panel or computer. The individual requesting access (typically someone who works at the site or is a guest) inserts their card into the slot and is granted entry or denied access based on that card’s programmed settings and access privileges. Some card-based systems require the card to be swiped or inserted, while others require the card to be placed inside the slot.

Biometric Access Control Systems

A biometric access control system is an electronic authentication system that uses a person’s fingerprints, hand geometry, or a retina or iris scan to grant access. These systems can be installed at building entry points or used to control access to individual rooms or workstations. Biometric access control systems are used to control access to areas where security is of the utmost importance. Biometric systems are often used in conjunction with a card-based system. This allows for a more robust and foolproof system that can’t be hacked. The essential operation of a biometric access control system is to scan the person’s unique biometric identifier and match it with the person’s identity. If the two match, the person is granted entry. If they don’t, they are denied access. 

Electronic Entry-and-Exit Registration Systems

An electronic entry-and-exit registration system is a computer-based system that tracks employees as they enter and exit a building. It is often installed in industrial environments, where many employees enter and exit the facility at different times of the day. This system is helpful for business owners who want to track when employees start and stop work and how often they leave the facility. It can also determine if employees are clocking in or out at times they shouldn’t be, such as when they’re off the clock. This type of system can also be helpful in the healthcare sector, as it can be used to track when employees are entering and exiting the building to ensure they have a legitimate reason for being there.


Fingerprint Identification Systems

A fingerprint identification system is hardware or software-based system that uses a person’s fingerprints to identify them. It can be installed at a building entrance or used to control access to individual rooms or workstations. Fingerprint identification systems can control access to areas where security is most important. These systems can control: 

  1. Doors that lead to sensitive areas or workstations
  2. Entrances to buildings
  3. Security cameras
  4. Parking Lots
  5. Access to computer networks
  6. Building alarm systems.


Access control systems grant or deny access to a building, room, or computer network based on the person’s identity. There are several types of access control systems that are commonly used, including card-based, biometric, and electronic entry-and-exit registration. When choosing an access control system, selecting one compatible with your existing security equipment is essential. Additionally, it’s essential to select the system that best fits your needs and works in the environment where you’ll be implementing it.
