5 Types Of Access Control Readers

What are the types of access control readers?

1. Keypad Readers
2. Card Readers
3. Multi-Factor Authentication
4. RFID Readers
5. Mobile Readers

For your building’s security, there are several types of access control readers you can choose from. These readers are integrated into the access control system of your choice. When you’re upgrading your building’s security, you should choose the reader that best fits your premises. What kind of building are you in? What kind of doors or entry points do you have? Why do you need to install readers?

An access control reader is the component of the system that authenticates credentials. It’s through them that individuals gain (or are denied) access to parts of the building. The level of security they offer may vary depending on their functions, but any security measure can only be as secure as the people who use it. As long as every person is trustworthy, your access control system will be effective. Read on to learn more about the various types of access control readers.

Keypad Readers

Keypad readers are quite straightforward — they are devices that require employees to enter a PIN or a code. They’re effective and don’t need too many parts to install, but a code can easily be compromised. Anyone can share a code, accidentally blurt it out, or even forget it. Its advantage is that employees would not need something physical, like a card that can be lost or stolen, to get in.

Some keypad readers can double as controllers. Devices like the EL2301 also support magnetic, bar code, EM/HID proximity, Mifare, and biometric devices.

Card Readers

Because of their usefulness, card readers are becoming more common for buildings and companies nowadays. They can function in two ways: swipe and scan.

For swiping cards, readers read a magnetic strip on the card when you physically swipe them in the slot on the reader. This type of reader can be seen with older access control systems as modern technology allows for contactless scanning.

Scanning cards can be done using radio frequency identification or RFID. The reader can scan a card from a short distance, without the card ever touching the reader. Gaining door access with this type of reader would be easier than swiping a card, especially since sometimes, multiple swipes would be needed for a successful read.

If your access control readers are integrated into a holistic, comprehensive access control system, then a single card can be used for all functions such as door access, attendance, and lift access.

Multi-Factor Authentication

For extra security, some readers require two or more authentication methods. These are usually based on three things: something you know, have, or are.

The most common example that we might be familiar with is Google’s two-factor authentication where in addition to entering your password (which you know), you also enter a code sent to your phone (which you have). Biometrics scans a part of you that can’t be changed, something that’s part of who you are.

In access control systems, the typical multi-factor authentication involves a PIN/code and a card. Others add fingerprints to the mix. For example, a device like the EL363 has three operation modes: card, card + PIN, and PIN. If it’s set to the second option, then the employees would need multi-factor authentication before gaining access.

RFID Readers

Strictly speaking, RFID technology is used in some card readers as well. But RFID readers don’t always have to rely on cards. RFID readers are great because they don’t need any action to scan. You can simply walk past them, they’ll scan the tag on you (like on your ID, for instance), and it’s done.

ELID’s UHF RFID Integrated Reader has a reading range of 6-10 meters. This means that even when you’re that far away, the system can scan you and give you access to the area. It is incredibly useful in parking management and manufacturing control as well.

Mobile Readers

Some situations can call for the use of mobile readers. ELID’s C71 Mobile Computer is a great example as it has many functions that can help with access control as well. Its operating system is Android 8.1 / 11.0, and it has an Octa-Core processor. It looks like a typical cell phone, but its features include barcoding, iris and fingerprint recognition, and card scanning.

Mobile readers would not be the first choice for access control. However, in less than ideal working conditions or when the wired system is not functioning properly, using a mobile reader for identification and access can be extremely helpful.

Key Takeaway

Any of the types of access control readers will be a good addition to your security and access control system. Choosing one should only depend on your specific needs and resources.
