F39-EJ1220-D Application Field and Working Principle

The F39-EJ1220-D RFID tags are typically used in various access control applications, item identification, document identification, asset management, or user identification. More specifically, the tags are used to monitor and control access to both industrial and residential facilities.

The RFID systems consist of tags, readers, antennas, and basic software. The tags are small smart cards that contain information used to track and identify objects. RFID readers are the devices used to scan the tags. The readers interfaces to the system computer, which can be a PC or a control system. Antennas are used to radiate the signals between the tag and the reader.

Working Principle

The F39-EJ1220-D utilizes a special RFID technology known as near field communications. This type of communication uses a special type of radio frequency signal that is transmitted from the tag to the reader. This transmission of RF signals allows the electromagnetic interaction between the F39-EJ1220-D tags and readers. When the reader senses a valid signal, it authenticates the tag by sending out a unique identification that corresponds to the tag. This authentication is then used to allow access to a particular area.

Once the authentication is successful, the tag transmits a signal that is received by the reader and decoded. The reader then communicates with the access control system, allowing a user access to the protected area. This process is repeated each time the tag is used to gain access.

The F39-EJ1220-D technology is simple yet powerful. It has helped many companies increase security and productivity by ensuring that only authorized persons gain access to a particular area. The technology is also cost-effective, as it requires minimal setup and maintenance, and is easy to use.

Conclusion

The F39-EJ1220-D RFID tags offer a secure and reliable way to control access to restricted areas. The tags are simple to use and maintain, and are cost-effective. This technology is an ideal solution for companies that are looking for an efficient and secure solution for tracking and controlling access.
