RFID is the abbreviated form of Radio Frequency Identification. RFID is akin to the bar codes but in RFID the electro magnetic coupling is used to transmit signals. The main components of an RFID are silicon chips, an antenna and a transceiver that can be used anytime and anywhere. The passive RFID tags require no power source while active ones with power backup.

RFID is like a tag in which information and instructions are stored. It can be used in a car manufacturing, into a dog collar etc. An RFID system can range up to 90 feet. Unlike barcode technology, RFID does not require line-of-sight reading on which a bar code depends and RFID scanning can be done at greater distances than bar code scanning.

RFID has a plethora of uses. While initially the technology was just confined to tracing or identifying dogs, for a means of permanent identification number, the uses of RFID have simply multiplied over the years. Today RFID technology is seen in almost every field. Be it medicine, education (like library work), shipping, electronic devices automobiles, musical instruments, tracking movements of individuals via their passports etc., everywhere the RFID technology is at work.

RFID is becoming more widespread due to the manufacturing of RFID software. For instance lately technology company Intermec has created a new kind of intelligent RFID reader that can automatically route and manage information from RFID tags from remote locations, by using the IBM
