What is it?
- RFID is a passive wireless technology that allows an object or person to be tracked or matched.
- Tags and Readers are the two main components of the system.
- The reader sends out radio waves and receives signals from the RFID tag, while the tag communicates its identification and other information via radio waves.
- To be tracked, a tag may be read from up to several feet away and does not need to be in the reader’s direct line of sight.
- Active RFID tags are RFID tags that have their own power source. Passive tags are those that do not have a power source. The reader’s radio frequency (RF) scan temporarily activates a passive tag.
