RFID technology is the realization of the global
supply chain transparent a crucial technology. And
non-contact identification technology, RFID system
without contact between the transponder and reader
can complete the identification, relative and bar code
technology, and RFID technology to identify distance
more far; therefore it can be widely applied in
occasions. Along with large scale integrated circuit
technology, the RFID system greatly reduced the
volume, has been initially into the practical stage.
RFID is a non-contact automatic identification
technology, which can identify the moving objects,
the simultaneous identification of multiple objects,
non contact mode and no intervention has been
widely used in industrial automation, business
automation and information automation and many
