  1. Types of RFID Tag Passive, Active, metal mountable, specialty tags, etc. RFID tags contain antenna to enable them to receive and respond to radio-frequency queries from an RFID transceiver

  2. Types of RFID Tag (cont.) • Active - with battery for transmit/receive • Semi-active - use battery only when triggered • Passive - no battery, relying on the collection of RF power from reader for tag operation

  3. RFID Tag – Size Reduction Left: 3x2” RFID PCB in 1980 Right: .25” square module holds all circuitry and components in current technology

  4. RFID Tags – What’s New? • New Technology • New manufacturing processes • Anti-Collision algorithms • Smaller/better chips • New Standards • Auto-ID Center • Standard, inexpensive tags • New Economics • High Quantity/Low Price spiral • New applications • Goal -> a few cents per tag Smaller, Cheaper & Better RFID Tags are driving new applications 資料來源:Sun Microsystems
