RFID tags contain antenna to enable them to receive and respond to radio-frequency queries from an RFID transceiver
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
RFID Tag – Size Reduction
Left: 3x2” RFID PCB in 1980
Right: .25” square module holds all circuitry and components in current technology
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
