What is barcode?


5/37

Introduction

A barcode is an optical machine-readable representation of certain

data, which shows certain data oncertain product originally.


6/37

How barcode represent data?


7/37

Barcode represent data in thewidths (lines) and the spacing of parallel lines, and referred to asliner or 1D(1 dimensional)barcode and also referred 2D(2dimensional) barcode orsymbologies.

HISTORY

The first barcode wasdeveloped in 1948 by twograduate students at Drexel isInstitute of tecnology,bernardsilver and Norman Josephwoodland. They filed for a uspatent in October 1949 and itwas grated in 1952.


9/37

First use of barcode

The first use of barcode was to label

railroad cars. but they were notcommercially successful until theywere used to automate checkoutsystem, a task in which they havebecome almost universal.


10/37

How barcode can read?

Barcode can read by its reader or

scanners.


11/37

Barcode Reader


12/37

Barcode reader is used to readbarcode it tells us the originaldata.Barecode reader are builtfrom a fixed light and a singlephotosensor that is manuallyscurebbedacross the barcode.


13/37

How barcode readerworks?Barcode reader use a photosensor (A type of sensor that detects the presence of an object

through the use of a beam of light) toconvert the barcode into an electrical signalas it moves across a barcodeThe scanner then measure the relativewidths of bars and spacing,translates thedifferent patterns back into regularcharacters and sends them on to ascomputer or portable terminal.

USESOn grocery store productsDepartment store

Mass merchandiser (uses upc)Barcode are widely used in shopfloor control applicationssoftware where employees canscan work orders and enter thetime spent on a job.


21/37

BenefitsFast-selling items can be identified quicklyand automatically reordered to meetconsumer demand.Slow-selling items can be identified,prevention a build-up of unwanted stock.The effects of repositioning a given productwithin a store can be monitored allowingfast-moving more profitable items to occupythe best space.


22/37

Historical data can be used to predictseasonal fluctuations very accurately.Items may be repriced shelf to reflect bothsale prices and price increases.

Radio Frequency Identification


25/37

RFID: What it is?

Radio-frequency identification (RFID) is an automatic identification method,relying on storing and remotelyretrieving data using devices called RFID tags ortransponders.

RFID (radio frequency identification) is a technology that incorporates the useof electromagnetic or electrostaticcoupling in the radio frequency (RF) portion of theelectromagnetic spectrum to uniquely identify an object,animal, or person.

An alternative to bar code. RFID is also called dedicated short range communication.


26/37

History of RFID:

Invented in 1948 by Harry Stockman.

Initial application was during World War II-The UnitedKingdom used RFID devices to distinguish returning

English airplanes from inbound German ones. RADAR was only able to signal the presence of a plane, notthe kind of plane it was..

Came into commercial use only in 1990s.


27/37

Components of RFID.


28/37

Active RFID TAGS:

Battery Powered tags Have much greater range 100m Hold much more information Kbytes Can integrate sensing technology

Temperature, GPS Can signal at defined time Multiple tags can be recorded at once

Used for higher value items Shipping containers Babies Electronic assets

Cost between $20 and $40 per item Life between 2 4 years


29/37

Passive RFID Tags:

Tag contains small chip, and a small antenna that stores a small amount of data.

Tags can be programmed at manufacture or on installation. Tags are powered by high power electromagnetic field generated by antennas

usually in door ways.


30/37

Electronic product code-EPC

Each tag contains a unique code that facilitating theidentification process & is known as EPC.E.g. 613.23000.123456.123456789 (96 bits)Header defines version of EPC(8 bits)EPC Manager describes originator of EPC (Productmanufacturer) (28 bits)Object Class - Could describe the product type (24 Bits)

Serial Number

Unique ID for that product item (36 Bits)


31/37

RFID Vs Bar Code

RFID BARCODEForging is difficult. Forging is easy.

Scanner not required. No needto bring the tag near thereader.

Scanner needs to see the barcode to read it.

RFID is comparatively fast.

Can read multiple tags. Can read only one tag at a time.


32/37

Used where unique identification is needed.Large Retail companies Product Tracking.Hospitals & Nursing Homes Patient Tagging .

Airports Baggage Tracking.

Security Applications Contactless Smart Cards.RFID Readers could also WRITE onto Tags.RFID Sensors to sense temperature, movement, radiation, food quality.Passports-UK, Australia, Finland, Ireland.RFID is used in Libraries.Replacing Barcodes.

Uses of RFID:


33/37

Initiatives in RFID.

Patni Computer Systems Lab Implemented Animal Tracking SystemWipro Technologies - Member of the Electronic Product Code (EPC)Setting up a lab to study RFIDWorking on pilot projectsInfosys Technologies RFID consulting on logistics player in the RFID space.

TCS have tied up with Hyderabad university to produce RFID tagged mark sheets & degrees to deter use of fake degree.Intell icon - pilot project for BEL Bangalore, tags installed on employee buses.Buses inside the BEL campus were tracked with the aim of gauging employee

punctuality


34/37

Issues / Concerns

Cost of RFID technology. Active RFID life. 2-4 years.Extremely weather.

Security concerns. Illicit tracking of RFID tags.Global standardization.Environmental concern. Recycling RFID system are vulnerable to virus.


35/37

Conclusion

Gillette & Co:

Objective: To Track movement of product from PackagingCentre to Plants distribution centre.

Previously- >Using Bar Code, time taken=80 sec to 20 min.

In 1999-> With RFID it takes 20 seconds.

Gains->Gillette saves 20% in Operational Cost at each Distribution Centre.
