  1. 1. Radio Frequency Identification for supply chain management in retail industry..<br />Presented by...,<br />S. SYED NIZAMUDEEN<br />
  2. 2. What is RFID?<br />Radio Frequency Identification<br />RFID is the use of small devices that can be electronically identified at a distance, through many obstruction, using radio waves or adjoining frequencies.<br />Advantages<br />Works under adverse conditions<br />Reading is done without any human intervention<br />Read writer can be used to record new information on the tag<br />The use of radio frequency tags to identify real objects.<br />
  3. 3. Real Tags<br />
  4. 4. Frequency Ranges<br /><ul><li>Low – 100-500 kHz
  5. 5. short range, low data rate, cost, & power
  6. 6. Intermediate – 10-16 MHz
  7. 7. medium range and data rate
  8. 8. High – 850-950 MHz & 2.4-5.8GHz
  9. 9. large range, high cost, high data rate
  10. 10. needs line of sight</li></li></ul><li>Identification<br /><ul><li>Assign IDs to objects
  11. 11. Link the ID to additional information about the object
  12. 12. Link the ID to complementary info
  13. 13. Find similar objects</li></li></ul><li>Identification Examples<br /><ul><li>Bar Codes
  14. 14. License Plates
  15. 15. Social Security Numbers
  16. 16. Student ID
  17. 17. Serial Numbers
  18. 18. Car Keys
  19. 19. Database Keys</li></li></ul><li>How Does RFID Work?<br /><ul><li>3 Components
  20. 20. Transceiver – Tag Reader
  21. 21. Transponder – RFID tag

  23. 23. Supply chain management<br /><ul><li>It is a network of facilities and distribution options that performs the functions of procurement of materials, transformations of these materials into intermediate and finished products, and the distribution of these products to the customers.</li></li></ul><li>
  24. 24. Why supply chain management need RFID ?<br /><ul><li>Measurable impact to labor costs
  25. 25. Real reduction in errors via automation – reduction in mis-shipments, lost inventory, and errors in redundant data reads
  26. 26. Real gains in productivity by better managing the use of skilled resources through automation
  27. 27. Industry recognized qualitative impacts which returns improved customer service, lessened warrantee handling,
  28. 28. Driving regulatory impacts through compliance activities to meet governmental regulations
  29. 29. Automated POS means skilled resources are in front of your customers – and not behind a cash register</li></li></ul><li>What makes RFID relevant now?<br /><ul><li>After decades of technology refinement these radio tags have now become very small and inexpensive
  30. 30. A great deal of innovation has brought us to the point where the silicon core of an radio tag is now 0.4mm
  31. 31. The antenna can be printed onto a product’s packaging at time of manufacture
  32. 32. Currently radio tags can be purchased for less that €0.25 in quantity.</li></ul>=> RFID is small enough, fast enough, and cheap enough to doreal work with today<br />
  33. 33. Retail supply chain<br />RFID<br />
  34. 34. BENIFITS OF USING RFID IN RETAIL<br /> SUPPLY CHAIN<br />For manufacturers;<br /> RFID enables detailed, automated monitoring of parts as they move through a facility. RFID quickly identifies the origin of defective components or products, even after they have been sold. <br />Fordistributors;<br /> RFID manages inventories and fleets so effectively those manual tasks can be eliminated, processes can be dramatically accelerated, and shipping errors can be reduced. <br />
  35. 35. For retailers;<br />RFID ensures appropriate stocking levels, tracks the origin and history of products, prevents theft or misplacement of goods, and speeds up checkout lines. Where traditional bar coding requires one-by-one scanning of a visible bar-code label,<br /> RFID readers can simultaneously scan hundreds of tagged items, regardless of whether the tag is visible. And whereas traditional bar coding can tell you only what type of product is being scanned, <br />RFID can uniquely identify individual items. <br />
  36. 36. RFID’s Advantages<br /><ul><li>Passive
  37. 37. wireless
  38. 38. Store data on a tag
  39. 39. Can be hidden
  40. 40. Work in harsh environments
  41. 41. Low cost?</li></li></ul><li>RFID’s Disadvantages<br /><ul><li>Lack of standards!
  42. 42. Short range
  43. 43. Cost</li></li></ul><li>Conclusion<br /> RFID is an emerging technology that is likely to replace the conventional barcode technology, due to it’s many advantages on the former. Even if some controversies exist against use of RFID tags as they invoke privacy concerns as they can be monitored regularly from far apart, users are getting to co-op with it. Hence more advancement is yet to be done in this field to get better results with high efficiency and low cost.<br />
