  • 1. Tracking Using RFID BY: HIMANSHU SAXENA CS-6A IILM-CET, GR. NOIDA
  • 2. INTRODUCTION TO RFID• Radio Frequency Identification: Technology that uses radio-frequency waves to transfer data between a reader and a movable item to identify, categorize, track...• RFID is fast, reliable, and does not require physical sight or contact between reader/scanner and the tagged item
  • 3. REINVENTING THE BARCODES• RFID tags are an improvement over bar codes because the tags have read and write capabilities.• Data stored on RFID tags can be changed, updated and locked.Few Disadvantage of Barcodes:1. In order to keep up with inventories, companies must scan each bar code on every box of a particular product.2. Going through the checkout line involves the same process of scanning each bar code on each item.3. Bar code is a read-only technology, meaning that it cannot send out any information.
  • 4. DEVELOPMENT OF RFID CONCEPT First use of RFID device – 2nd world war – Brittan used RFID-like technology for Identify- Friend or Foe First RFID Patent - 1973 Auto-ID center founded at MIT – 1999 Standardization effort taken over by EPC Global (Electronic Product Code) The plane on the left is friendDon’t Shoot! We Plane on the are British right is foe
  • 5. COMPONENTS OF RFID SYSTEM• Tags - These are the heart of an RFID system, because they store the information that describes the object being tracked. Specific object information is stored in the memory of tags and is accessed via the radio signal of RFID readers.• Readers and Antennas - RFID readers are devices that convert radio waves from RFID tags into a form that can be passed to middleware software. An RFID tag reader uses antennas to communicate with the RFID chip. There are a variety of different readers as follows : 1. Handheld readers 2. RFID readers embedded into mobile data collection devices. 3. Fixed readers• Middleware - Middleware software or applications are needed to manage the flow of data from readers and send the data to back-end management systems. RFID middleware assist with the following: 1. Retrieving data from readers. 2. Filtering data feeds to application software. 3. Generating inventory movement notifications. 4. Monitoring tag and reader network performance. 5. Capturing history.
  • 6. VARIOUS TAGS• Inductively Coupled RFID tags: Were complex systems of metal coils, antennae and glass. Inductively coupled RFID tags were powered by a magnetic field generated by the RFID reader.• Capacitively Coupled RFID tags: Were created next in an attempt to lower the technologys cost. These were meant to be disposable tags that could be applied to less expensive merchandise and made as universal as bar codes.Basic Types: Active • Tag transmits radio signal • Battery powered memory, radio & circuitry • High Read Range (300 feet) Passive • Tag reflects radio signal from reader • Reader powered • Shorter Read Range (4 inches - 15 feet)

  • 8. APPLICATIONS OF RFID• People Tracking: Hospitals and jails are most general tracking required places. Hospital uses RFID tags for tracking their special patients. Many jails of different US states like Michigan, California, and Arizona are already using RFID-tracking systems to keep a close eye on jail inmates.• Document Tracking: Availability of large amount of data and documents brings lots of problem in document management system.• Healthcare: Patient safety is a big challenge of healthcare . Reducing medication errors, meeting new standards, staff shortages, and reducing costs are the plus points of use of RFID solutions. RFID wristbands containing patient records and medication history address several of these concerns.• Manufacturing : RFID technology provides an easy way to manage a huge and laborious manufacturing process. This type of process helps in better analysis, reduced time in locating parts and products and production process based sensors can be installed to alert any anomalies.
  • 9. ADVANTAGES DISADVANTAGES• RFID tags are very simple to • It is difficult for an RFID reader to install/inject inside the body of read the information in case of animals, thus helping to keep a RFID tags installed in liquids and track on them. metal products.• The RFID tags can store data up to • RFID technology has been 2 KB. referred to as invasive• RFID technology cannot be easily technology. replicated and therefore, it • Many countries have different increases the security of the range of frequencies that allow product. RFID tags to function.
  • 10. CONCLUSION• RFID technology can be the next tool for success and management of various businesses. With more research, the flaws and limitations of this technology can be removed.• This will make RFID technology very useful for diverse sectors like retail, transport and jewelry businesses.• RFID MARKET
