Physical access control limits access to facilities to authorized users only. Unauthorized users who gain physical access to systems or data can potentially compromise security and privacy. For this reason, it’s important to implement physical access controls to protect buildings and systems. There are a variety of physical access control methods available for developers, owners, property managers, and tenants. Keep reading to learn more about how to choose the best physical access control method for your organization.

Physical Access Control Methods

Physical Access Control System

Physical access control is a security measure employed to deny unauthorized individuals physical access to a facility or secured area. There are various methods that can be used to secure physical access.

One of the most common methods of implementing physical access control is using ID cards or badges. Employees and other authorized personnel are issued ID cards that must be presented to gain access to restricted areas. ID cards also allow facilities to keep track of who is entering and exiting the premises.

Door locks and keypads are other common means of controlling access. Doors can be locked with a keypad combination or key, preventing anyone without the proper code or key from entering. This system is often used in conjunction with security cameras so that employees can verify the identity of anyone attempting to enter the facility before permitting them entrance.

Alarm systems are another common method for controlling access. When an unauthorized person attempts to enter a restricted area, an alarm will sound, notifying staff members so that they can take appropriate action.


Turnstiles are one type of physical access method. They restrict access to a certain area by requiring individuals to pass through them in a specific direction. These can be manual or electronic and can be either single-file or multi-file.

Manual turnstiles consist of a series of rotating arms that must be pushed past in order to enter the restricted area. They are often used in conjunction with other physical access control methods, such as security guards or locked doors, to provide an additional layer of security.

Electronic turnstiles use sensors to detect whether an individual has passed through them properly and will not allow entry if they have not. This provides added security against unauthorized entrance into the restricted area. Electronic turnstiles can also be programmed to allow only certain individuals’ passage, depending on their clearance level, using key fobs, badges, or pin codes.

Facial Recognition Software

The use of biometric systems for physical access control is becoming more common. A biometric system uses a person’s unique physical characteristics to identify them. This can include fingerprints, eye scans, or facial recognition. A biometric system can control access to a building or specific areas within a building.

Facial recognition software uses facial features to identify an individual. This technology has been used for many years in different industries but has recently become more prevalent in security. Facial recognition software compares an individual’s facial features with the images stored in a database. If there is a match, the individual is granted access to the facility.

The accuracy of facial recognition software depends on several factors, including the image’s quality and the database’s size. But it’s one of the most accurate methods for identifying individuals.

Facial recognition software is often used with other physical access control methods, such as door locks and card readers. When used together, these methods provide a high level of security for facilities and organizations.

 Key Cards

Physical Access Control Methods

Key cards use a plastic card with an embedded microchip to allow or deny access to a building or room. The key card is swiped through a card reader, which reads the chip and either allows or denies access. Key cards can be used in place of traditional keys and can also be used to track employee movements and time tracking.

Physical access control methods are important because they provide a layer of security that can help protect an organization’s assets. These methods can help prevent unauthorized access to facilities, systems, and data and can help to deter and detect unauthorized activity.
