Everything Should Know About RFID Access Control - Nephsystem


Have you ever heard of RFID (Radio Frequency Identification) system? Well, it is the wireless non-contact access of radio frequency waves in order to transfer data. With the RFID tags, users can find and track assets and inventory automatically and uniquely. Using Long range rfidreader, you can find and track high value and large assets across large spaces.

In fact, RFIS takes the barcode technology to the next stage by letting tags to be read without any line of sight and based on the RFID type. Usually, it has a read range between the few centimeters to more than 20+meters. Right from its first-ever application of finding airplanes, RFID comes a long way and improve itself every year. As a result, it becomes more efficient and cost-effective.

Applications that benefit from the RFID are endless and spread in several areas such as inventory tracking and supply chain management.  Among huge applications, which use RFID technology successfully, RFID access control is the most important one. Keep reading the blog because we have mentioned many interesting things about the access control of RFID in this blog!


Access Control Management System in RFID

One of the most common accesses of RFID is the access control and door-entry systems for the authorized persons. The primary principle upon which RFID tags used is the identification badge of the workers of any industry or workers. Normally, it uses the low frequency for the badge detection.
For the access control system, RFID usually contains the components such as RFID tag, RFID reader, access control panel, and card access management software.  In the RFID card/tag, the information of the object or person is stored electronically, which contains information such as price, identification number, and code.

The RFID reader has the antenna that sends the radio waves to find an RFID tag/card within its range. It differs for the RFID reader based on the frequency of the emitted radio waves and then it decodes the uniquely stored details in the RFID card. Finally, it sends the signal directly to the host software.  The software reads the received signal from the RFID reader and then rejects or grants the access to the person.
