In 1979, EVVA rings in a new era of security technology with MCS. The system was developed in collaboration with Vienna's Technical University and has become one of the world's most well-known security products. The reason? For 40 years and MCS has been and is still to this day considered 100% copy-proof. Consequently, demand is still high today – especially in highly sensitive industries, such as aerospace, the industrial sector, financial industry and health care. The magnet technology is resistant to all magnetic fields that are found in daily life and forms part of EVVA’s extensive list of patents.
