Operating mode:

The operating mode of the reader is "passive or active". In general application, the reader is in the receiving state. It receives the signal from the active electronic tag in real time and transfers the received data to the backstage management system. In special applications, tags can also be written or parameters of it can be changed. It has the features such as fast reading and writing, long distance and excellent anti-collision ability. It has shown its own competence at the entrance or exit of a large parking lot, at the gate of a primary and secondary school or at a toll station on a highway, or even on a coal mine shaft, and in other applications.

Recognition range:

When the reader and active tags cooperate in good visual environment, the maximum range can reach up to 100 meters. Compared with passive tags, its super-strong signals and super-long recognition distance have great advantages in specific applications.

When users have different requirements for recognition rang, active electronic tags and the readers with different signal intensities are chosen under complex application environment. And the required range can be achieved by adjusting the gain of the reader through software.

Recognition speed & capability:

When the active tag runs at a speed of up to 200 km/h within the effective range of the reader, stable recognition are ensured. The feature is especially suitable for the identification of the moving vehicles and passengers.

The reader can read more than 500 active tags at the same time, and the recognition accuracy is 99.999%. In a quite short time, it can ensure all the recognition without omission. The feature is especially suitable for the personnel management of schools and large enterprises, as well as the application of a large number of assets monitoring and warehousing management.

Communication security:

When the reader and the active tags communicate, special communication protocol is used to verify the legitimacy of the device. In order to prevent data cracking, the perfect meticulous encryption algorithm is developed to ensure data security in the communication process.


The product fully considers the application requirements of industrial environment such as lightning protection, waterproofing and shock protection. The production process of the reader strictly conforms to the ISO 9001 quality standard. Multi-step quality inspection is implemented to ensure good performance and quality of the products.

Interface standard:

The reader provides standard hardware interfaces such as RS485, RJ45 etc. If RS232, TTL or WiFi are required, please mark out when ordering. The company provides standard software interface that conforms to windows operating system platforms. Underlying communication protocols are also provided.
