Radio Frequency Identification

RFID is being touted as the best source of identification and tracking in today?s world. RFID or Radio Frequency Identification is an automatic identification method that uses RFID tags and readers.

RFID technology uses radio waves and it is possible to find a product or an object with an RFID tag without coming in contact with it. An RFID tag having a unique tracking number or identification data is embedded into the object. The RFID tag or the microchip is connected to an aerial. This aerial helps the chip to transmit radio waves with the stored information. The signal is picked up by an RFID tag reader and the reader transmits this information to a computer in digital format, letting us find out the information with a push of a button.

Though there are many advantages of using RFID technology. However, only a few that are common in all RFID tags are mentioned.

? Ability to read and write
? Contact not required to read the data
? The functioning is completely automated
? It is resistant to things like paint and dirt
? Can function at different frequencies
? Distance of reading can range from few inches to several feet

RFID technology is not just about collecting data but ensuring that the data is turned into actionable information that businesses can use. By using RFID technology businesses can reduce costs through increased productivity and reduction in lost items. RFID technology can give businesses a competitive advantage never before envisioned. There is great potential for using RFID technology in retail, healthcare and pharmaceutical industries.
