Many manufacturers use the tags to track the location of each product they make from the time it 's made until carried out of the retail store.

Most people are not even aware of all ways these tags are integrated into our lives and the ways this technology may affect them. RFID technology is under the main supervisory body of the ISO/IEC. The ISO/ETC is a joint technical committee of the International Standards Organization (ISO) and the International Electro technical Commission (IEC). Its purpose is to develop, maintain and promote standards in the fields of information technology and Information and Communications Technology (RFID Technology, 2012). To get a RFID system to work you need three parts; a scanning antenna, a transceiver and a transponder (the RFID tag). The scanning antenna puts out radio-frequency signals in a relatively low power and has a short range. The RF radiation does two things; it provides a means of communicating with the transponder and it provides the tag with the energy to communicate (passive RFID
