2. INTRODUCTION Radio Frequency Identification (RFID) technology is a non-contact, automatic identification technology that uses radio signals to identify, track, sort and detect a variety of objects including people, vehicles, goods and assets without the need for direct contact (as found in magnetic stripe technology) or line of sight contact (as found in bar code technology). RFID technology can track the movements of objects through a network of radio-enabled scanning devices over a distance of several metres.

3. HISTORIC DEVELOPMENT OF RFID The first RFID application was the "Identification Friend or Foe" system (IFF) [Wiki-RFID] [Wizard Wars] and it was used by the British in the Second World War.Successors of this technology are still used in armies around the world. The first commercial RFID application was the "Electronic Article Surveillance" (EAS). It was developed in the seventies as a theft prevention system. It was based on tags that can store a single bit. That bit was read when the customer left the store and the system would sound alarm when the bit was not unset. In the end-seventies RFID tags made its way into the agriculture for example for animal tagging.

4. HISTORY In the eighties RFID technology got a boost when Norway and several US states decided to uses RFID for toll collection on roads [EZ-Pass]. In 1999 the Auto-ID Center at MIT was founded. Its task was to develop a global standard for item-level tagging. The Auto-ID was closed in 2003 after completing the work on the Electronic Product Code (EPC). T he probably first paper related to RFID technology was the landmark paper by Harry Stockman, "Communication by Means of Reflected Power" in October 1948. The first patent on RFID was issued in 1973 for a passive radio transponder with memory [US. Patent 3,713,148].

5. RFID TAG A device called an RFID tag (or simply a tag) is a key component of the technology. An RFID tag usually has at least two components: 1. An integrated circuit for modulating and demodulating radio signals and performing other functions; 2. An antenna for receiving and transmitting the signal. RFID tags that do not have any integrated circuit are called chipless . RFID tags also known as RF fibres . An RFID tag can perform a limited amount of processing and has small amount of storage.

6. RFID TAG DESIGN

7. CURRENT RFID TECHNOLOGY RFID transponders (tags) consist in general of: Micro chip Antenna Case Battery (for active tags only)

8. RFID TAGS TYPES

9. RFID PRINCIPLES ACTIVE PASSIVE Active tags require a power source they’re either connected to a powered infrastructure or use energy stored in an integrated battery. In the latter case, a tag’s lifetime is limited by the stored energy, balanced against the number of read operations the device must undergo. Example: T he transponder attached to an aircraft that identifies its national origin. Passiv e tags don’t require batteries or maintenance. The tags also have an indefinite operational life and are small enough to fit into a practical adhesive label. A passive tag consists of three parts: an antenna, a semi- conductor chip attached to the antenna, and some form of encapsulation. The tag reader is responsible for powering and communicating with a tag.

13. SIMPLIFIED RFID SYSTEM

14. HOW DOES RFID WORK? Systems that make use of RFID technology are typically composed of three key elements: 1. An RFID tag, or transponder, that carries object-identifying data. 2. An RFID tag reader, or transceiver, that reads and writes tag data. 3. A back-end database, that stores records associated with tag contents.

15. APPLICATIONS OF RFID IN LIBRARY

16. APPLICATIONS OF RFID IN AGRICULTURE The role and practises of (Radio Frequency IDentification )RFID-enabled sensor network automation in agriculture is in areas such as environmental monitoring, precision agriculture, machinery management, facility automation and agricultural traceability. RFID-enabled sensor networks have the potential to revolutionize soil ecology by offering measurements of granularized temporal-spatial information on soil quality. A computer assisted decision making module is essential in precision agriculture to calculate and facilitate variable controls for all involved applications. In food industry, it is important to track and trace products by case or by item for safety and security reasons as well as for fine-grained decision-making and control.

17. ADVANTAGES OF RFID OVER BARCODE RFID BARCODE Forging is not easy. No need to bring tag near reader. Comparatively faster. Can read multiple tags. Expensive. It is usually reusable within factory premises Forging is easy Scanner need to see the barcode to read it. Slower. Can read only one tag at a time. Relatively cheaper. It cannot be reused.

18. CONCLUSION As a bank of information, RFID technology needs to evolve in these modern days with increase in technologies. Adopting this new technology for people's welfare which increases facilitates & leads a better life for humans.
