· Product Name: 925 Vehicle Type Electronic Tag
· Product Model:


The vehicle type electronic tag is an active RFID tag that is mainly used in vehicle management. The tag and the registered vehicle is a consistent one-to-one match when it is used. The one-to-one match helps to fully realize automated wireless management. The tag has many characteristics such as long read/write distance, high recognition accuracy rate, strong anti-collision performance, low power consumption, and replaceable battery, etc. It has been well applied in vehicle management system and parking lot application.

Product Description

Operating mode:

The vehicle type electronic tag operates in an ‘active or passive mode’. The tag actively transmits a signal or is triggered by an instruction from a reader (or a low-frequency activator) to transmit a signal. The RF frequency is adjustable. Activators distributed in various zones or inside and outside the access control have been actively transmitting low-frequency signals at a low frequency of 125 KHz. Any vehicle type electronic tags that pass through the activator signal range can be activated successfully. And the digital number transmitted by the activator is obtained. The RSSI field strength value is calculated. The vehicle type electronic tag then transmits data such as "tag ID + tag status + activator number + RSSI value" at 2.4 GHz frequency.

Recognition range:

The vehicle type electronic tag is an active tag which has great advantages such as superior strong signal and long recognition range compared with the passive tags. In a good visual environment, the maximum identification range can reach up to 150 meters.

Access identification

A low-frequency 125KHz activator can be placed inside and outside the access control respectively. The effective activation distance could be adjusted by changing the antenna position, adjusting the transmit power, and choosing different antenna shapes and dimensions. The tags will be activated by the activators inside and outside in turn when the tags pass through the access control. According to the activating order, the entry and exit judgment could be accurately made. Also the accurate floor location could be determined.


Real-time locating

According to the characteristics of 125KHz low frequency such as field strength RSSI value, strong penetrating power, clear boundary, easy adjustment of signal range, etc., several activators can be used for real-time locating of RTLS zones.

Anti-dismantle function

The vehicle type electronic tag has an anti-dismantle function. After the tag is installed, if unauthorized person dismantles the tag without permission, there will be wireless or alarm. It is convenient for comprehensive management and background abnormal situation monitoring.

Button function

The vehicle type electronic tag has a button. In special application, if an abnormality occurs, the tag button can be pressed. When the button is pressed, the red light is on. Then the background monitoring software will promptly remind the relevant person or the vehicle about the abnormality. Safe actions will be taken rapidly. 

Communication security:

Special communication protocol and encryption algorithm are used to verify the legitimacy of the device. In this way, data security is ensured in the communication process.


The production process strictly conforms to the ISO 9001 quality standard. The product fully considers the application requirements of industrial environment such as lightning protection, anti-surge and anti-static.
