RFID Technology
An RFID system comprises a tag, an interrogator (the reader) and a host system. The host computer manages the information flow, sending to and receiving from the reader and tag. The data flow between the reader and tag occurs over an air interface, or radio frequency (RF) link.
UPM Raflatac manufactures tags and inlays 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’s RF field is based on the well-known electrical resonance effect.
