Silver supply RFID tag, RFID antenna with a conductive silver paste supply, RFID or radio frequency identification system, also known as the wireless IC tag, electronic tags, electronic sensor chip, proximity cards, contactless cards, RFID tags and so on. Silver ink is a silver powder and thermoplastic resin as the main component of a liquid-type ink, in PET, PC, PVC sheet can be used on, have a strong adhesive force and hiding power, low temperature curing, controllable electrical conductivity and low resistance values. Mainly used for printing RFID antennas, instead of the traditional method or etching press foil made of metal antennas, printing easy, fast and efficient, is the printed circuit antenna and the preferred method.
