4. WHAT ISA BARCODE?
🠶 ITISAN AUTOMAT
IC IDENTIFICATION TECHNOLOGY
🠶 STRUCTURED TO CONTAINA SPECIFIC PIECEOF INFORMATION
🠶 BARCODES ISA PREDEFINED FORMAT OF DARK BARS WITHWHITE
SPACES
🠶 IN THE BARCODE SPACE ISCONSIDER AS ZERO AND BLACK BARS AS
ONE

5. HISTORY OF BARCODES
🠶 AS FAR BACK AS THE1960’S BARCODES WERE USED INDUSTRIALWORK
ENVIRONMENTS
🠶 IN EARLY 1970’S COMMON BARCODES STARTING APPEARING TO
AUTOMATETHE PROCESS OF IDENTIFYTHEGROCERY ITEMS,UPC
BARCODES WERE PLACED ON PRODUCTS.
🠶 SOME OF THEEARLY IMPLEMENTATIONS OF BARCODES INCLUDES THE
ABILITYTO IDENTIFYRAILS, CARS…ETC.
🠶 THETECHNOLOGY ISBORN ON 26THOF JUNE 1974 THEWRIGELY JUICY
FRUITGUM OF 10 PACKS WASFIRSTSCANNED PRODUCT.

6. TYPES OF BARCODE
🠶 LINEAR BARCODE(CONS
ISTOF BLACK BARSAND WHITESPACES)
CODE11 CODE128 CODE39 UPC etc.
🠶 2D BARCODE(COMPOSED OF GRID OF LIGHT AND DARK MODULES)
DATA MATRIX AZTEC CODE QR-CODE etc.

7. HOW IT WORKS?
🠶 EACH BARCODE LABLE HAVE A FEW DIFFERENTPARTS:-
MANUFACTURER’S ID
PRODUCT IT
EM NUMBER
CHECK DIGIT
🠶 THEFIRSTFIVE NUMBERS SEEN ON THE LABELS REPRESENTSTHE
MANUFACTURER’S ID
🠶 THE NEXTSETOF FIVE NUMBERS ISTHE PRODUCT ITEM NUMBER

8. 🠶 EACH PRODUCT HAVE A UNIQUE PRODUCT IT
EM NUMBER
🠶 CHECK DIGITISTHEFINAL NUMBER ON THEBARCODE LABLE WHEN
SCANNER READS THE BARCODE THE DIGIT HELPS ITTO VERIFY THAT THE
BARCODE HAS BEEN READ CORRECTLY

9. BARCODE SCANNER
🠶 THESEARE AN ELECTRONIC DEVICE TO TO READING PRINTED BARCODES.
🠶 A BARCODE SCANNER USESA PHOTO SENSOR(OPTICAL TECHNIQUE) TO
CONVERT THEBARCODE INTO AN ELECTRICASIGNAL.
🠶 TYPES:-
🠶 PEN S
TYLE SCANNERS
🠶 SLOTBASED SCANNERS
🠶 CCD READERS(CHARGE COUPLED DEVICE)
🠶 CAMERA BASED SCANNERS
🠶 LEASER BASED SCANNERS

10. APPLICATION OF BARCODES
🠶 FOR DEPARTMENTALSTORES
🠶 FOR LIBRARIES
🠶 FOR INDUSTRY
🠶 HEAL
THAGENCIES
🠶 DOCUMENT TRACKING

11. FACTS FOR SUCCESS
🠶 BARCODE LABLESARE CHEAP
🠶 ITMAY BE READ BY GREAT ACCURACY
🠶 STANDARD S
IMBOLOGY ISDEVELOPED
🠶 USERFRIENDLY TECHNOLOGY

12. ADVANTAGES

13. DISADVANTAGES
🠶 SYSTEM FAILURE MAY COST MORE DELAY.
🠶 SCRATCHED OR CRUMPLED BARCODES AY CAUSE PROBLEMS.
🠶 DAT
A MUSTBE CODED INTO T
HE BARCOD.
🠶 IN LASER SCANNING DURABILITY& COST ARE TWO DISADVANTAGE.

14. CONCLUSION
🠶 POSIT
IVE IMPACT ON DAILY LIFE.
🠶 HAVE LOSTSOF ADVANTAGESWITHMINOR BOTTELNEAKS.
🠶 ITHAS IT’SVESATILE USE & ITISUSERFRIENDLY.
🠶 LASEREMISSION ON HUMAN BODY ISHARMFUL FOR SKIN.
