Abstract As the standard of living constantly boosts and retailing sector develops, the total amount of goods in the world is continuously rising。 However, traditional bar coda only contains little information, rely excessively on the database and it can be easily defaced, which make it difficult to meet the actual needs。 On the other hand, RFID is a perfect solution to the above-mentioned problems since it possesses many merits such as the anti-fouling ability, read-write feature as well as the capacities of simultaneous multiple tags reading and the screen-free reading。 Shipping statistics of a large number of goods in the supermarket and regular inventory counts are collected automatically, greatly improving the accuracy and efficiency of the data input。

Adopting ISO 15693 protocol standard, this design can read and write RFID tags that are up to this standard。Finally, the data to be written and read is shown on display interface。 The design for RFID reading and writing device is pided into two modules, namely hardware and software modules。

Firstly, this paper briefly introduces the RFID technology, followed by the introduction of reading and writing of the RFID module of the hardware system,the control processing module, antenna and the tag chip。 The following part is about reading and writing software module, radio frequency identification (RFID) system that accords with the ISO 15693 standard protocol, the communication protocol, anti-collision protocol, modification nof encryption keys and other software modules。At last, it is the experiment test and analysis of application design。

Keywords: RFID; RFID tag; Reader; ISO 15693 protocol standard; Anti collision
