Copprint

Copprint makes nano copper conductive inks for printed electronics from Jerusalem, and its relevance to RFID is the antenna. Copper ink lets antennas be printed additively rather than etched from foil, and avoids the cost of silver, the usual alternative for printed conductors. Its LF361 ink is formulated for antenna and RFID work, and the company also markets compostable RFID antennas, aimed at the point where tag volume and end of life disposal start to matter commercially.
