Radio-frequency identification.

RFID is a technology that uses radio-frequency waves. RFIDuses tags as a component to transfer data between a readerand a movable item(middleware), which can be used toidentify, categorize & track the data.

RFID is fast, reliable, and does not require physical sight orcontact between reader/scanner and the tagged item.

A Tag is a transponder which receives a radio signal and inresponse to it sends out a radio signal.

It contains an antenna, and a small chip that stores a smallamount of data.It can be programmed at manufacture or on installation.It is powered by the high power electromagnetic fieldgenerated by the antennas.A multiple number of the tags can be read at a time.Tags can be attac hed to almost anyt hing.Two types: A ctive & Passive .


6/25

A ctive tags Passive tags

Powered by an internal

battery.Finite lifetime.Greater range. (Up to 100 M)Relatively Expensive.

($50 - $250)

Better noise immunity.Higher data transmission

rates.

Operate without battery.Derive power from the field

generate by the reader.Less expensive.($0.50 - $5)Weak range. ( 3 5 M)Subject to noise.Require more powerful

readers.Very sensitive.

The objective of the Electronic Product Code (EPC) is toprovide unique identification of physical objects.

Header defines data type.EPC Manager describes originator of EPC (Productmanufacturer)Object Class - Could describe the product type.Serial Number Unique ID for that product item.

RFID reader is a device that is used to interrogate an RFIDtag.

This is how the Reader works:The reader has an antenna that emits radio waves.The tag then responds by sending back its data.

The reader has two basic components :A scanning antennaA transceiver with a decoder to interpret the data

In short: Data Processing.

It provides reader connectivity to other systems on thenetwork, translates that data and transmits it to otherapplications.

Transport and logistics : toll management, tracking ofgoods.

Se curity and acc e ss control: tracking people (studentsetc.), control access to restricted areas.

Supply chain manag e m e nt : item tagging, theft-prevention.

Me dical and pharmac e utical applications :identification and location of staff and patients, assettracking, counterfeit protection for drugs

Manufacturing and proc e ssing: streamlining assemblyline processes.

Agricultur e : tracking of animals, quality control. Etc.

P ublic s e ctor: passports, drivers licenses, counterfeitprotection for bank notes, library systems.

If RFID tags wer e widely de ployed, r eta iler s could r educestand ing invento r ies by 5%, wa r ehouse labo r by 7.5%, andpr oduct losses by 1% of sales.

RFID will also facilitate self-se r vice checkout p r ovidingcons ide r able sa vings to sto r es and ot he r establ ishments(e.g., l ibr ar ies).

What will happen if in the coming years, nearly everything istagged with a RFID chip?

---- Privacy

RFID is a very hot, hyped field right now; Normal people thinkit s the best thing ever, while privacy advocates think it s theworst .

1940 1950

Based on the experiences with radar usage and radio broadcast technology in the year 1948 a firstscientific article about RFID was announced.

1950 1960

First explorations of RFID technology, laboratory experiments too place.1960 1970

Many theories concerning RFID were developed.First commercial usage in connection with electronic article surveillance equipment to countertheft.

1970 1980

Many institutions (academic, governmental, business) were actively working on RFID and manyadvances have been made during this time.Some early adopter implementations like vehicle tagging or animals tagging have been realized.

1980 1990

Many commercial applications of RFID entered mainstream.Electronic toll collection on roads became the main field of interest in many countries around theworld

1990 2006RFID became widely deployed and therefore a part of everyday life.Beginning of using the same tag for several purposes (toll collection, parking lot access, farecollection, campus access, ).A lso several standards have been adopted.

PresentlyWidely used.


24/25

It s far too early to determine how RFID will be rolled outand what, if any, will be the privacy and consumerprotection issues.

As a result, policy makers should respond to this newtechnology the way they have dealt with all newinformation technologies: if and when problems arise,address them at the time.
