What Are RFID Door Locks In Access Control Systems?

Access control systems help to do exactly what their name implies, they control who can and can’t access an area. They can also control when the public can access different areas. These systems are made out of a variety of different devices. An RFID door lock is one of those systems. RFID is an electronic type of door lock and in today’s article we will explore further into how they work.

RFID stands for Radio Frequency Identification, it is an extremely short-range radio emission that sends a code to a reader to unlock a door. By having a radio emission, you can tap your card instead of having to use older “card swipe” style technology. This leads to less wear and tear on the card and more versatility.

On almost all RFID systems a keycard can be used to trigger the system. These cards are about the same size as a driver’s license or a work ID card. In fact, many companies that implement RFID door lock systems use their RFID cards as work ID by printing employee information onto the card.
Some systems will also recognize an RFID keyfob. These are small plastic devices that contain the radio transmitter inside. They are small enough to go on a keychain without taking up too much space. The downside of these devices is that they aren’t as convenient to have out if you have to use access control frequently.

Types of RFID Readers

RFID readers, the portion that accepts the short-range single, can take various forms. The most common in many workplaces is a simple black plaque that reads the signal and then sends that signal to the electronic lock on a door to release.

Not all RFID readers are just card readers though. You can get them with various features included.
For example, a second level of access control can be added to the RFID reader. Combo RFID readers will have the reader and a secondary method of authentication such as a keypad or biometric reader. 

These function in one of two ways. Option number one, you can use the access control methods independently so either can unlock the door. Or the second option is to require both authentication methods before the door will unlock.

Other RFID readers can be built into the handle of the door so that it has a sleek appearance and is centralized.

RFID Works On Many Types Of Doors

One of the beautiful things about RFID is that it works on many different types of doors. You can use it on traditional doors that have a handle and open manually. Electronic latches or electronic handles can be installed on these doors in order to control when they are open or closed.

RFID also works on automatic doors. The card reader can control when the door opens and when it doesn’t.

Other types of doors such as garage doors, high security doors, glass doors, cages, fences, and more can also be added to an RFID system so that you can secure your whole property without worry.

Shut Off Access At Any Time

Employees come and go, sometimes they get fired. It is important to be able to remove access to your facility at a moment’s notice and traditional keys can make that extremely problematic. Electronic access controlsystems like RFID can be programmed by a computer on the go. That means that you can change a person’s access levels whenever you need to.

RFID door locks are used around the world and are trusted to be secure. The key to having a secure RFID system is to find a trusted system made by a reliable manufacturer and installed by a trusted company. With one of these systems in place, you will have a property that is as secure as you want it to be.

How Often Do Stores Check Their Security Cameras?

Security cameras have been in use in stores for ages and since they were first used they have helped to stop crimes. Stores of all kinds have implemented security cameras. Grocery stores, convenience stores, electronics stores, and even clothing stores all have security cameras on the property.

Some stores have video monitors positioned around the store so that staff can always observe what is happening o
