Radio Frequency Identification:
RFID is an Automatic Data Capture technology that uses radio-frequency waves to read a movable item to identify, categorize & track...
RFID is fast, reliable, and does not require physical line ofsight or contact between reader/scanner and the RFID tagged item.
INTRODUCTION OF RFIDINTRODUCTION OF RFID
HISTORY OF RFIDHISTORY OF RFID
• In 1945, Léon Theremin invented an espionage tool for the Soviet Union which retransmitted incident radio waves with audio information.
• Mario Cardullo's device, patented on January 23, 1973, was the first true ancestor of modern RFID, as it was a passive radio transponder with memory.

What is RFID? -- The Tags
Tags can be attached to almost anything:
pallets or cases of product vehicles company assets or personnel items such as apparel,
luggage, laundry people, livestock, or pets high value electronics such
as computers, TVs, camcorders
What is RFID? -- The Tags
Tags can be read-only or read-writeTag memory can be factory or field programmed and optionally permanently locked (security)Data written to the tagleft unlocked, can bemodified over more than100,000 times, allowing thethe tag to be reused or updated
Advantages of RFID Systems
Ability to read data without visual access Ability to read data from moving objects Ability to read data at distance, from 3cm to
100 metres Ability to secure the tag data Ability to update data in the tag (write) Ability to have automated read of tags. Ability to have the tag form to suit the
application
RFID in Defence Applications
Inventory and Asset management using long range RFID tags (6 metres)
Securing and sealing slow moving inventory High accuracy in location and quantity ofInventory Automatic confirmation for picking and
deployment of inventory, using fixed and mobile readers
Inventory user identification Allocate inventory to individual users
automatically
• 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
RFID advantages over bar-codes
• Hidden placement of tags• Unique identifiers for all objects worldwide• Massive data aggregation• Unauthorized development of detailed profiles• Unauthorized third party access to profile data• Hidden readers

Privacy: The flip side of RFID
Strengths
Advanced technology Easy to use High memory capacity Small size
Weaknesses
Lack of industry and application standards
High cost per unit and high RFID system integration costs
Weak market understanding of the benefits of RFID technology
Opportunities
Could replace the bar code End-user demand for RFID
systems is increasing Huge market potential in many
businesses
Threats
Ethical threats concerning privacy life
Highly fragmented competitive environment
