Radio Frequency Identification

According to studies, the price of RFID will approach $0.05-0.10 if purchased in bulk. When this trend continues, it would not be long before the market will lean towards the RFID due to cost-effectiveness, thus, possibly defeating the role of barcodes that are widely used for commercial purposes with about 5 billion worldwide occurrences daily. One of the organizations that are working to regularise RFID is EPCGlobal Inc., which is a cooperative effort between UCC and EAN. These are the two parties responsible for the application of barcodes in the U.S. and European markets (RSA Security, 2004b).Through the advantages brought about by the RFID, problems in the privacy of consumers are raised by certain groups. Concerns on the possibility of detecting the possessions of the consumers without their knowledge are the main objective of these groups. If access to being able to detect and read the RFID were given to the wrong hands, possibilities such as robbery and other crimes are at hand. Also, business groups perceive the possibility of RFID being a tool for company surveillance. As a possible answer to the security issues, RSA Security provides ways to validate RFID readers and to be able to make protected internal transactions (RSA Security, 2004a).The Radio-Frequency Identification or RFID is made up of a silicon microchip that is fastened to an antenna. It comes in many forms and shapes. It can be approximately one-half millimeter in size while other kinds can be implanted in materials as thin as paper. Upon activation from the reading device, the RFID tag sends a signal which can be translated as a distinct number that can identify the particular item. In this effect, the RFID tag does not require a power source because it can be considered as inert and works only when stimulated. There are already practical uses of this technology. One application is for proximity cards that are used more conveniently than metal keys.
