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 rfid reader, you can find and track high value and large assets across large spaces.
Due to the improvement in technology, there are many devices available in the fields of RFID. The advanced technologies are helpful for people to do their day to day activities easily. These devices are helpful for tracking the devices with the help of radio frequencies. The RFID technologies are useful in asset tracking, proof of delivery, inventory control, and much more.
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.
Access Control Management System in RFID
One of the most common accesses of RFID is the access control and gate-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.
