Radio frequency identification or RFID is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna allows the chip to transmit the identification information to a reader. The reader converts the radio waves reflected by the RFID tag into digital information that can be transmitted to computers that can use it. RFID is not necessarily "better" than bar codes. The two technologies are different and have different applications, which sometimes overlap. The big difference between the two codes is of bars are line of sight technology. That is, a scanner to "see" the barcode to read, which means that people often have to orient the bar code towards a scanner to be read. Radio frequency identification, by contrast, requires no line of sight. RFID tags can be read, provided they are within range of a reader. Bar codes have other shortcomings. If the label is ripped or soiled or has fallen, not no way to explore the subject, and standard bar codes identify only the manufacturer and the product, not the single theme. The bar code on a milk carton is the same as everyone else, making it impossible to identify which one might pass its expiration date first. RFID is therefore definitely the best technology, depending on the needs of users. However, each new technology brings, apart from the obvious benefits, some serious disadvantages too. Thus, Albert Einstein could never have imagined that his equation E = MC2 could one day be used to make nuclear bombs. RFID also brings serious considerations RFID tags can invade individual privacy and security. And hospitals in the U.S. are taking into account the implementation of RFID chips inside the bodies of patients, and tracking them back to trends in health care. Agro Many American companies are using RFID tags to track animals such as cows, pigs etc.Soon large companies could consider the deployment of RFID chips and tags on your employees to track in and out of the office. If this is not an invasion of privacy, then invasion of privacy has to be redefined. The ability of governments to planting these 'Spychips', as it is called a chip RFID, in the bodies of citizens and monitoring their every move and action is clear and distinct.Enemy Nations could deploy these within Spychips who handle sensitive portfolios in National Defense and the Armed Forces. Spying and espionage techniques could face revolutionary changes, eliminating the need for physical presence of spies inside enemy terrirtory. A combination of spy satellites and Spychips could cause privacy as a thing of the past. These are real concerns. Laws must be set to counter this possibility, ensure the sovereignty of personal privacy and limit the use of labels RFID chips.
