Automatic Identification

• Technology for identifying items
• Three step process
• 1) Identify people/objects
• 2) Obtains information
• 3) Transfers data to computer

3
Radio Frequency Identification

• Auto ID with a wireless system
• Via radio waves
• No physical contact with product

3 Parts to the RFID System

• Antenna
• Transceiver with a decoder
• Tag or transponder

5
How the System Works

• Antenna sends out radio signal
• Reader sends out electromagnetic waves
• Tag passes through electromagnetic zone
• Tag transmits data to reader
• Reader decodes data from tag
• Data gets passed into a computer

Tags Active vs Passive
Active Passive
Powered by an internal battery Obtain power generated from the reader
Data can be modified/rewritten onto the tag Tags are read-only and cannot be modified
Greater size Much lighter than active tags
More expensive Less expensive
Limited operational life Unlimited operational life
Longer read range Shorter read range
