  3. Background of RFID

  4. 1. Background of RFID (1/4) Basic concept behind RFID is same as “Mirror-Sunlight-Reflection theory ” Invented in 1948 by Harry Stockman Initial application was during World War II-The United Kingdom used RFID devices to distinguish returning English airplanes from inbound German ones Commercial Operation begun from 1960’s
  5. 1. Background of RFID (2/4) RFID = Radio-Frequency Identification Briefly the RF stand for “radio-frequency” and ID means “identifier” that allows an item to be identified, accessed, stored, reprogrammed and communicated by using radio waves The acronym refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less.
  6. 1. Background of RFID (3/4) Manufacturing and Processing Supply chain management Security Controlling access to building Payment systems Location Tracking Retail
  7. 1. Background of RFID (4/4) RFID advantages over bar-codes No line of sight required for reading Multiple items can be read with a single scan Each tag can carry a lot of data (read/write) Individual items identified and not just the category Passive tags have a virtually unlimited lifetime Active tags can be read from great distances Can be combined with barcode technology

  8. Concept of RFID

  9. Basic Components of RFID RFID Tags (or Transponders) (or Interrogator)
  10. Database Backend Gateway Reader Application Tags Scanned Database User Interface Fig.1. A General Overview of RFID Architecture 2. Concept of RFID (1/7) RFID Architecture Firstly items-tag are scanned by reader; Secondly in backend transmitted data coming through antenna (RF-wave) are being recognized by RFID-based system PC. It acts as a middleware communication gateway among items, reader and system database; Finally it filters out and store data in RFID-databases for checking the data fault and relevant operation.
  11. Key component - tag 2. Concept of RFID (2/7) 1. Chips: Hold information about physical object. 2. Antenna: Transmit radio signal 3. Package: Encases the Chips and Antenna, so that can be attached to the physical object.
  12. 2. Concept of RFID (3/7) Are All Tags The Same? Three Basic Types: Active Battery powered memory, radio & circuitry Long Read Range (300 feet) Active Backscatter (Semi-active) Reader activates tag, but battery powers memory and circuitry Medium Read Range (10 - 50 feet) Passive Backscatter Reader powered Shorter Read Range (4 inches - 18 feet)
  13. 2. Concept of RFID (4/7)RFID Tag Operational Frequencies
  14. 2. Concept of RFID (5/7)RFID tag memory Read-only tags Tag ID is assigned at the factory during manufacturing Can never be changed No additional data can be assigned to the tag Write once, read many (WORM) tags Data written once, e.g., during packing or manufacturing Tag is locked once data is written Similar to a compact disc or DVD Read/Write Tag data can be changed over time Part or all of the data section can be locked
  15. 2. Concept of RFID (6/7) Key component - Reader Reader functions: Remotely power tags Establish a bidirectional data link Inventory tags, filter results Communicate with networked server(s) Can read 100-300 tags per second Readers (interrogators) can be at a fixed point such as Entrance/exit Point of sale Readers can also be mobile/hand-held
  16. Reader Products Network Readers OEM Reader Boards Serial Readers OEM Reader Boards Peripheral Controllers PC Card Readers RFID Enabled Label Printers Portable Readers Wireless Integrated Handheld Reader
  17. 2. Concept of RFID (7/7) Key component – Host computer data acquired by the readers is then passed to a host computer run specialist RFID software or middleware to filter the data route it to the correct application, to be processed into useful information

  18. Advantages

  19. 3. Advantages of RFID (1/8) 1. RFID tags can hold higher data capacity and better capability RFID tags can hold more data than bar codes.
  20. 3. Advantages of RFID (2/8) 2. The technology of RFID is efficient Does not require a direct line of sight Read at much greater distances up to 300 feet Read multiple product at the same time Read through packaging Provide unique identification
  21. 3. Advantages of RFID (3/8) 3. RFID tags can be used different environments RFID technology has been widely in the medical industry Animal identification Human identification
  22. 3. Advantages of RFID (4/8) 4. RFID tags provide higher security Cannot be easily replicated Stronger sensor networking system or monitoring system

  23. Disadvantages

  24. 3. Disadvantages of RFID (5/8) 1. High cost Hard to implement in low cost products The benefits of RFID > additional cost
  25. 3. Disadvantages of RFID (6/8) 2. Materials Problems Problems with some materials (Metals and liquids ) reflect the radio waves unreadable
  26. 3. Disadvantages of RFID (7/8) 3. Interference problem has been occurred The presence of mobile phone towers has been found to interfere with RFID radio waves
  27. 3. Disadvantages of RFID (8/8) 4. The risk of using RFID technology Do not need to have direct contact Consumers are apprehensive about their privacy Others can be tracked the personal information by the RFID reader
