RFID system builds full identification

The problem of how to safely identify the identity information of personnel in major occasions has not been well solved. At the 2007 Communication Exhibition, NEC unveiled the RFIDVIP personnel identification management system for intelligent identification through electronic tag RFID. The biggest highlight of it is different from the traditional identity access control system. It is intelligent identification and overall personnel positioning.

The so-called electronic tag RFID is one of the automatic identification methods of attaching a tag-shaped or card-shaped chip storing information to a person or an article, and reading and identifying with radio waves.

The NECRFIDManager system is composed of three parts: tag, reader, data transmission and processing system.

Features

99.99% read rate

The maximum reading range is 8 meters

At the same time can read the number of tags 320

Readable frequency range 860MHz ～ 960MHz

Communication rate 80Kbps, 160Kbps, 320Kbps, 640Kbps


The tag is also called an electronic tag or a smart tag. It is a chip with an antenna in the memory, and the chip stores information that can identify the target. RFID tags have the characteristics of persistence, strong penetration of information reception and propagation, large storage capacity and many types. Some RFID tags support reading and writing functions, and the information of the target object can be updated at any time.

The reader is divided into two types: handheld and fixed. It consists of a transmitter, a receiver, a control module and a transceiver. In data transmission and processing, the reader receives and reads the data by receiving radio waves from the tag.

The most common is a passive radio frequency system. When the reader meets the RFID tag, it emits electromagnetic waves, and an electromagnetic field is formed around the tag. The tag obtains energy from the electromagnetic field to activate the microchip circuit in the tag. It is converted into relevant data. The control calculator can process these data for management control.

The reporter experienced the operation of the system once on the spot. Test experience personnel wear RFID identification cards, and the system database records the basic information of the personnel corresponding to the RFID identification cards, including basic information such as name, age, gender, affiliation, work type, job title, personal photos, and expiration date. The card becomes effective after authorization.

Experience cardholders are recognized by the system when they pass through the location where the identification system is set. The system will read the card number information and pass the location and time of the cardholder through the system transmission network to the ground monitoring center. If the collected card number is invalid or enters the restricted channel, the system will automatically alarm and notify the monitoring center for control management.

Through the monitor, the management personnel can realize visual management, and the following information can be obtained during the whole process of monitoring the identity of the personnel: the number and distribution of cardholders, the area and activity traces of the designated cardholder at the current or designated time.
