The major components of an RFID system include an encoder, a transponder, a reader,
and software applications. The general RFID process begins with encoding a tag/
transponder with item-specific information. The tag then typically transmits data when it
enters the reader’s range. For passive tags, the reader emits an electromagnetic signal
that evokes the tag/transponder to allow its data to be read generally via ultra-high
frequency. Once the information is read by the reader, the information can be
transmitted, enterprise applications stored, and mined for a variety of information. |
