Access Control Readers: What They Are and How They Are Used

When it comes to allowing access to different persons in certain locations, there aren’t many things more crucial than installing a security system that works effectively. You need excellent access control card readers if your company has particular spaces that contain valuable or confidential information or products that should only be accessed by certain employees.

A typical security guard can be beneficial, but with current tech, access control card reader systems offer so many advantages and possibilities that you really can’t go wrong. Knowing the types of access control readers is beneficial to allowing companies in selecting the best type.

What is an access control reader?

An access control card reader, in basic terms, is a security system that needs a tap or swipe of an identification card to confirm the person entering the room or space is authorized. These are employed by many companies since some employees do not have the same access to information and clearance as managers.

Because of increased safety regulations, it has recently become a popular choice for hotels and tall enterprises. In many buildings, the elevator will scan your card as you ascend to your floor to ensure that only you and anybody else with authorized access can enter the area.

Types of access control readers and their function:

  • Card readers for keys

There are various kinds of keycard reader systems for access, such as key fob access, a magnetic card that functions similarly to a credit card. To enter a building, users swipe these cards over a reader.

The proximity card reader system enables remote communication between the card and reader, preventing physical touch between the two. After choosing a keycard reader system, the next choice is whether you prefer a wired or wireless one.

  • PIN readers and keypads

A PIN or passcode must be entered on an access control keypad to open a door or gate, which is a protective measure. The use of this kind of technology is common in apartment and office buildings. As a result, only the code is required to enter the building and no credentials are required.

Access control systems using keypads are often used in buildings with minimal security and high traffic. Although this kind of access control system is user-friendly and practical, there are some disadvantages as well. Since passcodes are easily shared, the main downside of this form of the access control system is vulnerability.

  • Authentication readers using two-factor or multifactor

As was already stated, keypad readers lack safety because passcodes can be easily handed to or exchanged with those who were not originally given access or the passcodes. When referring to door card readers or PIN readers, one solution to solve this is to use a two-factor authentication system.

This renders the card or passcode ineffective for gaining entry, requiring the use of a second authentication process, such as additional credentials. Security can be increased by integrating a card reader and a PIN reader. Multifactor authentication may also be used as an upgrade for institutions that demand more strong security measures.

  • Biometric fingerprint readers

Because every fingerprint is different, a fingerprint reader is a type of electronic security system that verifies a fingerprint before allowing someone access to a building. The most popular biometric reader used by access control systems is the fingerprint, although they can also employ iris or facial recognition to provide access.

To provide the maximum level of protection for structures that demand the strongest security measures, biometric access cards will pair a card reader and a fingerprint reader. Banks, research institutes, military facilities, and other extremely secure establishments where access must be controlled typically use biometric access card access control systems.

  • Key card readers with video

Every attempt to enter a building using a keycard can be documented on video because of an access control card reader with a built-in camera. This is done to make sure that the individual using the access card is the one who received it in the first place.
For most facilities that need stronger protection, this is the standard. This type of access control is now widely used in office buildings to monitor access and ensure that no card was stolen.

Not only does this provide safety and security, but it can also significantly save costs for businesses. Outdated keys are misplaced, and it might be costly to hire security to create a barrier. A system in place minimizes those expenses and sets a new level of satisfaction. In addition to being convenient, knowing who is coming and going is also beneficial for security and productivity purposes.
