The WE-T28K125 dual-band active RFID tag is a battery-powered active RFID tag. The tag has two operating frequency bands, 125KHz band and 2.4GHz band. The tag has location and inventory functions.

• The 4 GHz band is the main operating band for communication between tags and active readers;
• The 125 KHz band is used to wake up the dual-band tag that triggers the dormant state and receives the ID of the exciter;
• The operating mode of the tag is TTF (Tagged-To-Transmit-To-Transmit).

WE-T28K125 dual-frequency electronic tags are specially used for the management of electronic tags for personnel in and out of the door or goods in and out of the warehouse. Normally does not transmit signals, the label passes through the doorway, is installed in the doorway of the 125K low-frequency activator activation, transmits the 2.4G label signal. The 2.4G card reader near the door captures the label signal, can know that the label is passing through the door, and further through carries the activation source information to judge that the label is to enter the door or to go out, realizes the non-contact personnel to punch the card automatically and the goods to enter and leave the storehouse automatically to register, realizes the user's non-sensory personnel to take attendance and the goods to take stock of the management.

WE-T28K125 dual-frequency electronic tags of low-frequency activation distance up to 2 ~ 10 meters (different activator), 2.4G signal emission distance up to 100 meters, can also be used for important posts whether the personnel is off duty, important equipment whether to move the control.

WE-T28K125 dual-frequency electronic tags internal 2 CR2032 battery, support for not less than 1 million activations, the battery can be used up to replace the battery itself. Label can be reported on the real-time power, battery undervoltage to remind users to replace the battery in a timely manner.
