Compared with WIFI&Bluetooth, what are the advantages of active RFID?

Active RFID (Active Tag) is a type of RFID tag that is divided according to different power supply modes of RFID tags. It usually supports remote identification. Active tags are equipped with batteries and can be read from distances of tens or even hundreds of meters. Tags are also expensive and are often used to track high-value items from a distance.

Active RFID is battery-powered RFID technology at the Tag end. Because Tag is battery-powered, compared with passive RFID, it can transmit longer distances and adapt to more complex application environments. Compared with Bluetooth, Wi-Fi and other wireless communication technologies, active RFID requires only a simple transmission of ID signals, the system is simpler, lower power consumption, and lower cost. Therefore, although the overall market of active RFID is not large, it has irreplaceable advantages in some application markets.

Active RFID main applications

Compared with RFID in other frequency bands, the application of active RFID is narrow. The use of active RFID can make the ID signal of the tag transmit farther, and the environmental applicability is stronger. Based on this feature, the application of active RFID mainly includes the identification and positioning of personnel and the tracking and management of assets.

Electric bicycle management

Electric bicycle because of its convenience, has become one of the most common means of transportation in China, but the popularity of electric bicycle, also brought two problems, that is, how to carry out effective management of it, and anti-theft problem.

The use of active RFID, on the one hand, through the way of electronic fence, to promote the electric bicycle parked in the designated area, on the other hand, through the installation of readers at each intersection, the track of the electric bicycle monitoring, to solve the theft problem.

The campus RFID card

Campus card is also a concentrated field of active RFID applications, mainly to solve the problem of student attendance and school personnel positioning and security monitoring. Such application scenarios are mainly promoted by local governments. With the emergence of new technologies, other technical solutions have gradually emerged for such applications. The campus card market remains a major market for active RFID.

Asset management

Valuable asset management is a typical application scenario of active RFID, including the management of valuable medical devices in hospitals, the management of experimental equipment in schools, the management of production equipment in factories and so on.

More another RFID applications

In addition, passive RFID has many other applications, such as judicial prisons, livestock, warehousing and logistics, border management and so on. Because the characteristics of active RFID can be remote identification, so that in a specific range, effective management of personnel, capital management. Compared with passive RFID, active RFID has a longer distance and better performance. Compared with Bluetooth, Wi-Fi and other wireless communication technologies, active RFID has obvious cost advantages. Therefore, in many scenarios, active RFID is the optimal solution.
