As the world changes, businesses must adopt new access control methods to keep their employees and customers safe. One such method is the use of access control readers. These devices allow managers or employees to check the access status of individual areas within a building or office. This can help with overall operations and ensure everyone who needs access can have it. This article will discuss the different types of access control readers, their features, benefits, and some of the most popular options.

What is an Access Control Reader?

Control Reader

An access control reader is an electronic device that reads the access card’s embedded chip and verifies or authorizes the user’s identity before granting access to the secured area in which it is located. This can be done by reading the magnetic stripe on the card, scanning a barcode, or reading the EC (electronic chip) embedded in the card. The access control reader is what tells you that you are allowed to enter and that you are allowed to use certain machines or equipment.

One of the reasons access control readers are necessary is to prevent unauthorized entry or access. An access control reader is something that can be a source of confusion. They can be hard to recognize because they are small and inconspicuous in most buildings. Their size and function make them look like one more device used in a building, but they are the powerhouse behind many of the major elements of an access control system.

Considerations for Access Control Card Readers

Choosing the right card readers is crucial to the success of an access control system. It is important to determine the optimal technology and the appropriate level of security. Furthermore, the readers must be quite dependable in usage and simple to operate. Having an access control reader refuse entry is one of the most infuriating experiences imaginable. The only time someone should be turned away from a door is if they don’t have permission to use the reader, not because of a problem with the reader or how it reads the credential.

Types of Access Control Readers

There are different types of access control readers on the market today, but the most common types are:

Card Readers: Card readers are the standard for controlling entry at many businesses. Card readers read key cards, granting admission instead of requiring a code or key. Two main types of key card readers used for access control are magnetic and proximity. Magnetic key cards work similarly to credit cards in swiping through a physical reader. Access is granted or denied according to the system’s predetermined policies.

Access Control

To assess whether or not a cardholder is granted entry, proximity cards employ radio frequency identification signals rather than a physical reader. In the case of a security breach, both key card solutions provide detailed audit trails that show which cards were used at which doors. Using key card readers can improve security, but it’s important to remember that employees might easily misplace or share their cards with others, weakening your company’s defenses.

Keypad Readers: A keypad reader is another access control reader that allows you to enter a security code instead of swiping a card. These devices are often used as a second line of defense, such as when the doors in an entry area require physical keys.

Keypad readers can be used with both card and key options to ensure that users don’t have an easy time gaining entry by pretending they have a card or a physical key. Code systems should be sufficiently complex to deter hacking attempts, and keypads should be simple enough for end users to enter the correct code every time.

Two-Factor Authentication: To be considered two-factor authentication, access control readers must be used in conjunction with another form of identification. This can include fingerprints, retina scans, and other biometric information gathered from a person, but it is most often employed with card readers or keypads.

The first type of factor uses the methods detailed earlier by reading a card or entering a code into a keypad. This is the element that provides the first level of defense. The second factor, usually biometric, is used to confirm that the person who entered the first element is who they claim to be.

This second level of protection can be used alone or in conjunction with other forms of access control mechanisms. Systems that combine many different identification methods are sometimes referred to as multiple-factor authentication, depending on how many forms of identification are used.

Biometric Readers: A biometric reader, also referred to as a biometrics reader, is a device used in conjunction with proximity cards or keypads for access control. This access control form differs from card and keypad readers because it doesn’t use cards or codes. Instead, it uses information from the person who needs to enter the area.

Biometric Readers

Biometric readers are often used in combination with other elements of security, such as cameras or intrusion detection systems. The primary benefit of this access control is that it is more secure because the information used to verify the person’s identity is more difficult to obtain. Therefore, it is significantly harder for someone who wants to gain access without authorization to bypass the second layer of protection by using another means of identification.


In conclusion, access control readers are key components of any access control system. Without them, you risk unauthorized entry into areas where sensitive data or resources are stored. Access control readers are also used with other security measures such as cameras or intrusion detection systems to prevent unauthorized entry into secured areas. When used properly, they provide a level of security that would otherwise be impossible to achieve. They make it possible for a building’s occupants to enter the premises without using keys or cards, which is another important benefit of these devices. Access control readers can be used as keypads or card readers, each with its strengths and weaknesses. It is important to choose a system that fits your company’s needs and that you can use to secure all of your assets. This includes your data, assets, and physical spaces such as offices and buildings.

Therefore, when choosing an access control reader, focus on what you want in your building and its purpose. Then, consider an access control reader that provides the desired security level and can minimize potential problems through easy maintenance and low operating costs.
