  1. Developing RFID Application In Supply Chain Batbold Toiruul Supervisor Prof. Kyung-Oh Lee Database lab., Department of Computer Science Sunmoon University, Korea, 2005

  2. Introduction • Radio Frequency Identification • Three parts to an RFID implementation: • Tag (chip and antenna) • Reader • Database & software • Auto-ID (Automatic Identification) • EPCglobal Network A Study of developing RFID application

  3. Example of Tags&Readers A Study of developing RFID application

  4. Transponder Antenna Transponder receives signal Reader broadcasts signal through antenna Transponder is charged with enough energy to send back an identifying response Reader sends info/data to computer system for logging and processing Computer System How Does work RFID Reader A Study of developing RFID application

  5. RFID Technology • Each product has tag: • Passive tag, unique identifier number • Range (Up to 3-5m, usually less) • Energy from reader • RFID reader : • Use radio frequency and transmit ID string over serial port to PC (13,56 MHz and 915 MHz). • PC: Middleware software (appl.. and standard Savant) and connect to DB and EPCglobal network • RFID benefits: • More information • - Individual item data & tracking • No contact • No line of sight • Milliseconds • Simultaneous read of multiple items A Study of developing RFID application

  6. EPCglobal Network • Object Name Service • Static ONS • Dynamic ONS A Study of developing RFID application

  7. Typical Supply Chain A Study of developing RFID application

  8. RFID privacy • Eavesdropping • Very efficient to eavesdrop wirelessly at a high rate. • Traffic analysis • It is possible to track people’s movements, social interactions, and financial transactions by correlating data from multiple tag reader locations. • Spoofing • Deceiving the system into thinking that a product is still on the shelf or that it has a lower price than it actually does. • Denial of service • Disrupting supply chains by disabling many tags at once. A Study of developing RFID application

  9. The Purpose • Make RFID application software for the supply chain system • All information of products is stored on the database • Once product registered by reader then every action is automatically • Read products with tag by reader then show information of products from database A Study of developing RFID application

  10. System Overview A Study of developing RFID application

  11. <<sub-system>> Aggregation Center pay producer Shelve produce write tags affix tags mover query tag receive produce scan producer Inventory management view inventory View item receive payment aggregation clerk distributor bill distributor place order Order management track order create shipment distribution shipper track shipment ship Aggregation center A Study of developing RFID application

  12. Implementation(1/4) • PicoTag™ Tag • ISO 15693 Standard • Passive tag and 2kb of non-volatile read/write memory • Up to 1.5 m (gate antenna), 70 cm (single antenna) • 64 bits (unique serial number) • M300-2G Reader • 12V to 15V power supply • Host interfaces RS232 • Radio frequency 13.56 MHz A Study of developing RFID application

  13. Implementation(2/4) • Visual C++ • Ms-SQL, ODBC, RS232, TCP/IP A Study of developing RFID application

  14. Implementation(3/4) Aggregation center: In/Out Date Primary Key (Tag Code) Product name Producer In Money Out Money Product type Product name Counted Number Quantity Unit price The place of origin Producer ID (Farmer) Storage life Tag Code Name of Company ID of employee of Company Number of Distribution center Cost of track A Study of developing RFID application

  15. Implementation(4/4) • Producer section: producers all information • Producer is only add/deleted to/from database on this application or Web site • Also Product section has as same data of storage section. A Study of developing RFID application

  16. A Study of developing RFID application

  17. A Study of developing RFID application

  18. Results: A Study of developing RFID application

  19. Results: A Study of developing RFID application

  20. Conclusions • Developed the application software for the supply chain • All information of products is stored on the global database • Each subsystem can see more information of Individual item data & tracking on the application interface from global database • RFID benefits: • No line of sight • Miliseconds • Simultaneous read of multiple items A Study of developing RFID application
