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 Animal Traceability

RFID Application Points

CWireless

Bill of LadingMaterial Tracking

• Assembly Line

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
