Radio Frequency Identification (RFID)

RFID

RFID is a leading automatic identification technology. RFID tags communicate information by radio wave through antennae on small computer chips attached to objects so that such objects may be identified, located, and tracked. The fundamental architecture of RFID technology involves a tag, a reader, and a database (in a computer system).

A reader scans the tag and transmits the information on the tag(s) to a database, which stores the information. Transmitting identification data by radio rather than by manual transcription increases the quality, speed, and ease of that information transfer, which is the basis for the technology’s appeal. RFID tags can be installed on objects such as products, cases, and pallets.

Advantages of RFID:

v  No line of sight like smart card, barcodes is need and it provides flexibility

v  Accuracy in data transfer and Easy to handle (portable).

v  Good and efficient traceability and autoID system.

v  Reliable

v  Tamp proof and other hazard proof

v  Error free and provide maximum security

Applications of RFID

v  Animal Husbandry: the RFID technology in animal husbandry is used for animal tagging and tracking.

v  Asset Management: the RFID tags can be placed at places in the plant equipment, from where they are not visible to the human eye. RFID reduces the duplication and forgery in asset management.

Radio Frequency Identification is expected to be widely used in future as it can be embedded into everyday items as RFID tags. The RFID technology as the ability to track moving objects in real time enables user to have improved visibility into moving objects status and also to access information in a wide range. Now we embed this RFID system with context aware monitoring system which is an innovation in the web services and take services to the next level by which we can provide an effective web services by integrating technology like RFID.

Example: if a system (laptop) is embedded with RFID tag, then the details of the system is recognized by the RFID readers and the details such as date and time, location are fetched through readers. This detail intern transferred to the context monitoring services to sterilize the searching time and searching options .this helps the user to make narrow decisions without any confusion and time stamps problem.
