Product Description

 

About RFID

Automatic identification technology that uses radio frequency signals to achieve
non-contact information transmission through space coupling (alternating magnetic
field or electromagnetic field), and achieves the identification purpose through the
information. Conventional use in regional personnel positioning has great advantages.

Product summary

HC-PA08 round school badge tag can have multiple operating frequencies. 2.4GHz can be identified from a long distance, making it more secure. The tag emits signals spontaneously and can be recognized by RFID active reader without triggering. School LOGO and pattern can be printed according to customer requirements. This tag can be add 125Khz frequency, used a trigger to active the 2.4G work, so that it can much reduce the miss-reading possibility when too many tags move to active reader.

Product Feature
