Abstract
A wireless identification (RFID) tag, an electronic product PCB having same, and an electronic product management system using the RFID tag. The RFID tag includes an insulating means, a pair of upper terminals provided on the upper surface of the insulating means, a tag chip connected to the upper terminals, and a pair of lower terminals provided on the lower surface of the insulating means so as to face the upper terminals. The lower terminals are connected to first and second patterns of an electronic product PCB. When a radio wave radiated from a reader-writer is received in the first and second patterns, reactive coupling through an electric field is created between the upper and lower terminals, which are then electrically connected to the upper terminals. Since the pattern already formed in the PCB is used as an antenna, there is no need to form a dedicated antenna pattern.
