RFID Tag System and Data Stream Thereof

摘要

An RFID tag system comprises at least one RFID tag and a reader. The RFID tag outputs a data stream including a head with a plurality of bits set to a sequence of certain levels and a body succeeding the head. The reader can detect the coding frequency of the data stream outputted from the RFID tag according to the known levels in the sequence, and then, read the body data based on the detected frequency.
