  5. 5. RFID Stands For… <ul><li>R ADIO </li></ul><ul><li>F REQUENCY </li></ul><ul><li>ID ENTIFICATION </li></ul>
  6. 6. RFID Defined <ul><li>A technology which incorporates the use of electromagnetic coupling and radio waves to identify an object or person. </li></ul><ul><li>Made up of several components embedded into business practices to improve and transform key supply chain processes. </li></ul><ul><li>Provides a distinctive identifier for objects (similar in its purpose to bar codes or magnetic stripes on the back of credit cards). </li></ul><ul><li>RFID must be scanned in order to retrieve the needed information </li></ul>
  7. 7. History and Development <ul><li>First Developed during WWII. </li></ul><ul><li>Created from radar experiments. </li></ul><ul><li>British needed to identify their own planes “friendlies” from French planes “foes”. </li></ul><ul><li>Actual year of invention was 1948. </li></ul><ul><li>For years after first development a great amount of research on RFID was done until it was actually used in commercial application. </li></ul>
  8. 8. History Of Use <ul><li>After WWII security and safety was needed due to the use of nuclear materials, which lead to further developments in “tagging”. </li></ul><ul><li>RFID started being implemented in the 1970’s. </li></ul><ul><li>During this time the cost of each tag was excessive and the use was very limited. </li></ul>
  9. 9. RFID in the 1980’s <ul><li>The 1980’s bought a great amount of development. In 1987 Norway had implemented the first successful toll collection system. </li></ul><ul><li>Toll systems were considered to be the breakthrough product for RFID. </li></ul><ul><li>In 1981 railroads began implementing RFID as a solution for the environment of their industry. The railroads used RFID to keep track of rolling stock. The radio frequency was able to go a travel a longer distance, and had the ability to read through snow, fog, dirt, and direct sunlight. Before RFID the railroads were implementing bar code technology. </li></ul><ul><li>In 1988 the main effort of RFID shifted to new applications to do things such as improve performance, reduce costs and reduce size </li></ul>
  10. 10. 1990’s to Present <ul><li>From the 90’s to the present RFID manufactures are in deep competition to be the company to sell the cheapest, smallest and most reliable RFID device. </li></ul><ul><li>( Business Applications Section will talk more about RFID in present use.) </li></ul>
  11. 11. How Does RFID Work? <ul><li>RFID is comprised of three major components: </li></ul><ul><li>♦ An antenna or coil </li></ul><ul><li>♦ A transceiver (with decoder) </li></ul><ul><li>♦ Transponder (RF tag) </li></ul>
  12. 12. RFID In Use
  13. 13. Antenna or Coil <ul><li>The antenna emits radio signals to activate the tag and to read and write data into the tag. </li></ul><ul><li>The antenna is the channel between the tag and the transceiver, thus it controls the data attainment and communication. </li></ul><ul><li>The antennas are available in many different shapes and sizes. For example an antenna can be built into a doorframe in order to collect data from people walking through the door. </li></ul>
  14. 14. Antenna and Coil Continued… <ul><li>The electromagnetic field, which the antenna produces, is constantly present when multiple tags are continually expected. </li></ul><ul><li>If constant detection is not needed the field can be activated by a sensory device. </li></ul><ul><li>Depending on the antennas needs you could opt to make it a handheld or a fixed-mount device. </li></ul><ul><li>Often the antenna is packaged with the transceiver and decoder. </li></ul>
  16. 16. Transceiver (with decoder) <ul><li>The reader releases radio waves in ranges from one inch to 100 feet or more. The range depends on its output power and the radio frequency used. </li></ul><ul><li>When the RFID tag passes through the electromagnetic field it will then detect the reader’s activation signal. </li></ul><ul><li>At this point the reader will decode the data programmed in the tag’s circuit. </li></ul><ul><li>Finally, the data is passed to the host computer to be processed. </li></ul>
  17. 17. RFID READER
  18. 18. Transponder (RF Tag) <ul><li>RFID tags are the heart of the RFID system because they store the information that describes the object being tracked. </li></ul><ul><li>Tags are classified according to their abilities: </li></ul><ul><li>♦ Active </li></ul><ul><li>♦ Passive </li></ul><ul><li>♦ Read-Only </li></ul><ul><li>♦ Write-Once </li></ul><ul><li>♦ Read-Write </li></ul>
  19. 19. Active Tags <ul><li>Contain a battery that runs the microchip’s circuitry. </li></ul><ul><li>Tag is able to send a stronger signal to the reader due to battery. </li></ul><ul><li>Allows a read range of about one hundred feet. </li></ul>
  20. 20. Passive Tags <ul><li>Passive tags contain no batteries. </li></ul><ul><li>Passive tags get power from a reader. </li></ul><ul><li>Readers send electromagnetic waves that produce a current in the tag’s antenna which then powers the microchip’s circuits. </li></ul><ul><li>A passive tags read range is approximately thirty feet. </li></ul>
  21. 21. Read-Only Tag <ul><li>Read-only contain data such as tracking numbers. </li></ul><ul><li>These tracking numbers are usually serialized and pre-written onto them by the tag manufacturer. </li></ul><ul><li>Read-only tags are usually the least expensive because information can not be added onto them as they move through the supply chain. </li></ul>
  22. 22. Write-Once & Read-Write <ul><li>Write-once tags allow a user to write information into the tag one time during the production. The information can be something like a batch or serial number. </li></ul><ul><li>Full read-write tags allow for new data to be written to the tag as it is needed. These tags also allow for original data to be written over. </li></ul>
  23. 23. RFID TAGS
  24. 24. Business Applications
  25. 25. Asset Tracking <ul><li>RFID tags applied to company assets which are stored away </li></ul><ul><li>Companies then use the tags and RFID technology to locate assets when they needed </li></ul><ul><li>The location of the assets are accurate within 10 feet </li></ul><ul><li>Think of our Libraries… </li></ul><ul><li>RFID tracks library books that are checked out or in. </li></ul>
  26. 26. RFID Utilized in Manufacturing <ul><li>Manufacturing companies utilize RFID to track parts </li></ul><ul><li>Work-in-Progress tracking made easier </li></ul><ul><li>Reduce defects </li></ul><ul><li>Increase of throughput </li></ul><ul><li>Manage production of different versions of the same product </li></ul><ul><li>Assists in tracking part arrivals </li></ul><ul><li>Follows parts along assembly lines </li></ul>
  27. 27. RFID Used In Retail <ul><li>Assists in identifying which products need to be restocked </li></ul><ul><li>When shelf supplies are low store will be able to quickly identify where product is needed and where they will obtain the needed product </li></ul><ul><li>Overall, allows for higher customer satisfaction </li></ul><ul><li>Helps automate checkout lines </li></ul><ul><li>Reduces line waiting times </li></ul>
  28. 28. Payment Systems <ul><li>Helps speed up processes where payments are necessary. </li></ul><ul><li>Most commonly found on toll ways </li></ul><ul><li>Used in collecting tolls, which we know in Illinois as the IPASS system. </li></ul><ul><li>More convenient for drivers and eases the flow of traffic. </li></ul><ul><li>Mobil Speedpass </li></ul>
  29. 29. Security and Access Control <ul><li>Companies use RFID to assist in limiting access of unauthorized personnel to information among other things </li></ul><ul><li>Confirms information is only being viewed by those who are allowed to view it. </li></ul><ul><li>Added value to Electronic Article Surveillance </li></ul><ul><li>Commonly used in stored as anti-shoplifting tool it signals alarm to go off. </li></ul><ul><li>Control access to gates communities (ex: Crystal Tree, in Orland Park) </li></ul><ul><li>Controls access in Airports (O’Hare Airport) </li></ul>
  30. 30. Case Study #1: Victory Land Group <ul><li>A supplier company for Wal-Mart </li></ul><ul><li>Knew that it had to keep up with demand and competitors </li></ul><ul><li>Implemented Electronic Product Code (EPC) and RFID smart labels </li></ul><ul><li>Constructed a new distribution center with RFID capabilities </li></ul><ul><li>Zebra and R4 Global Solutions, a leading RFID systems integrator worked with VLG on the implementation and since then has worked with a dozen Wal-Mart suppliers. </li></ul><ul><li>Results: </li></ul><ul><li>* VLG is able to go onto Wal-Mart’s Retailer Link Supplier website to track the progress of its tagged merchandise. </li></ul><ul><li>* VLG uses the information for its own planning. </li></ul><ul><li>* Considering more ways to use RFID internally. </li></ul><ul><li>* Began discussing RFID technology with its own suppliers </li></ul>
  31. 31. Case Study #2: Federal Express <ul><li>Federal Express (world’s largest express parcel delivery company) </li></ul><ul><li>Delivers 3.2 Million parcels daily and operates over 42,500 vehicles worldwide. </li></ul><ul><li>Company’s couriers use an automatic keyless entry and ignition system which uses RFID transponders embedded into a wristband. </li></ul><ul><li>Results: </li></ul><ul><li>* Personnel do not have to worry about juggling and keeping track of their keys when delivering packages </li></ul><ul><li>* Carriers are more productive on their routes. </li></ul><ul><li>* If wristband is misplaced, the RFID system can reprogram a new code within a matter of seconds. </li></ul><ul><li>* When carrier places his or her band within 6 inches of the reader, the door will unlock, keeping all other doors locked in order to prevent unauthorized entry. </li></ul>
