UPM Rafsec - Technology

UPM Rafsec - Technology: "UPM Rafsec manufactures tags based on passive RFID technology. This means that they don't require an internal power supply or battery. The power required to energize the tag is drawn from the magnetic field created by the reader unit's antenna. The tag's ability to draw energy efficiently from the reader RF field is based on the well-known electrical resonance effect. "
