The Radio Frequency Identification (RFID) is quite a vast subject. It is used for so many different applications. The most developed area of research has first been to track animals. Nowadays, many pets have a chip hidden in their neck that permits to identify them very specifically as the information in the chip is unique. Some researches have then been oriented on the supply chain area. Unfortunately, as the technology is quite new, a lot of issues have not been solved yet. The purpose of this Master Thesis is to gather, to sort out and to clarify the more information on RFID technology as possible. Following this objective, the Master Thesis is articulated in three main parts. First, data transmission is explained so that the basis of the technology would be understood and this would also clarify some problems encountered later in the report. Then, the technology itself is described. As you will read, the principle looks pretty simple at first sight but then when going deeper in the working of it, you will see that it is not. While presenting the variety of different systems that coexist on the market, the problem faced by the enterprises to chose the best suitable one would become obvious. The thesis helps clarifying all of that. Finally the application of the technology in the supply chain, with its advantages and limitations is presented. I hope the knowledge put into this Master Thesis would clarify the world of the Radio Frequency Identification
