We Are EM Microelectronic!

“With over three decades of experience in RFID, EM Microelectronic is one of the pioneers in this field. It was 15 years ago that our company was the exclusive chip manufacturer of the first large-volume solution with RFID technology for Marks & Spencer. This project broke new ground, proving that such a project had a strong ROI, and that RFID was a robust solution for it, paving the way for today’s mass adoption of RAIN RFID in retail.”
