RFID tags contains a chip and an antenna, which sends a signal, using the energy of the reader. This signal contains information about the package or its contents. There are a variety of types of electronic tags that vary the parameters of memory, frequency, power, and cost. The most widely used type of passive tags that are only used to read information on approximately $ 0.50 per share, although it is expected that in the coming years, the cost of this technology will be significantly reduced. RFID technology is already used in a number of areas of our lives, for instance, identification badges, and devices for travel on toll roads, as well as supply chain management. In anticipation of reducing the cost of these devices several large retailers, in particular, Wal-Mart, Tesco, Target, have already announced their intention to apply the RFID- technology in their supply chain. Among the possible benefits of this technology - eliminating manual counting and bar-coding of incoming and outgoing materials , and automatic tracking of inventory levels , a small , fast and accurate product identification and selection of stocks , the reduction of marriage.
Although many large companies encourage their suppliers to invest in RFID- technology, the introduction of such systems is faced with great difficulties, expensive and requires several years to fully implement. Of course, RFID will advance to the next level of information security, information systems so the company must be able to receive, process and analyze the data collected in this way. The introduction of such systems due to additional investments in information technology and an invitation to consultants and experts in systems engineering. In addition, the introduction of RFID- technology must be accompanied by a certain degree of control processes.
