:RFID is a technology that uses a technique of frequency radio waves to exchange data between the reader (eng. Reader) and a device called tag (eng. Transponder). Tag contains a silicon microchip and an antenna. The antenna emits radio waves and thus sends the data to the microchip that the reader through the entries in the computer. The transponder is on the production and the packaging contains a unique serial number. RFID - technology is mainly used for the identification of packaging products to be transported, stored or periodically enumerated and is a type of electronic 'smart packaging' '(eng. Smart packaging). In order to approach the consideration of the application of RFID in traffic, it is necessary to first see how the system works, which are the basic elements of this technology, and the possibility of application in other systems. This paper presents the basics of RFID technology in terms of product identification in automated postal systems. These are the advantages of this technology as well as disadvantages, with particular emphasis on bar code technology that RFID system needs to succeed in the postal service.
