As far back as the 1960s, barcodes were used in industrial work environments. Some of the early implementations of barcodes included the ability identify rail,road,cars,etc…… In the early 1970s, common barcodes started appearing on grocery shelves. To automate the process of identifying grocery items, UPC barcodes were placed on products. Today, barcodes are just about everywhere and are used for identification in almost all types of business.

3. What is Barcode?
■ It is an automatic identification technology
■ Bar code is a predefined format of dark bars and white
spaces
■ Structured to contain a specific piece of information
■ It allows real-time data to be collected accurately and
rapidly
■ Combination of barcode technology with computer and
application software improves performance,
productivity and profitability

4. Why use Barcodes?
■ As far back as the 1960s, barcodes were used in
industrial work environments. Some of the early
implementations of barcodes included the ability
identify rail,road,cars,etc……
■ In the early 1970s, common barcodes started
appearing on grocery shelves. To automate the process
of identifying grocery items, UPC barcodes were placed
on products.
■ Today, barcodes are just about everywhere and are
used for identification in almost all types of business.

5. Barcode Types
1. The type of barcode to use for a particular situation depends
upon:The use.
2. The data encoded in the barcode.
3. How the barcode will be printed.
■ There are two types of barcodes:
1. Linear barcodes
2. 2D barcodes.

6. Barcode scanner
■ A barcode reader (or barcode scanner) is an electronic device
for reading printed barcodes. Like a flatbed scanner, it consists of
a light source, a lens and a light sensor translating optical
impulses into electrical ones.
■ Barcodes originally were scanned by special optical
scanners called barcode readers; later, scanners and interpretive
software became available on devices including desktop
printers and smartphones.
■ The first use of barcodes was to label railroad cars, but they were
not commercially successful until they were used to
automate supermarket checkout systems, a task for which they
have become almost universal.

8. • HOSPITALS: Barcodes can allow for the organization of large amounts
of data. They are widely used in the healthcare and hospital settings,
ranging from patient identification (to access patient data, including
medical history, drug allergies, etc.) to medication management.
• RETAIL: Speeding up checkouts and ordering.
• OFFICE: Recording transactions.
• HEALTH: Ensuring correct dosage and treatment.
• TRAVEL: Making ticketing more efficient, ensuring safety and speedier
check in.
• LIBRARIES: Logging borrowers and books
Applications of Barcode

9. ■ REPRESENT UNIQUE IDENTITY OF
A PRODUCT
■ ACCURACY OF DATA INPUT (ERROR
FREE)
■ LABOUR SAVINGS BY AVOIDING
MANUAL SYSTEM
■ MORE ACCURATE DESPATCH
■ COST EFFICIENT
■ REAL TIME DATA COLLECTION
■ MEASUREMENT OF WORK IN
PROGRESS THROUGHOUT THE
FACTORY
■ RAPID ACCESS TO TOTAL
PRODUCTION COSTS
Advantages

10. Disadvantages
■ System Failure may cost more delays.
■ Scratched or crumpled barcodes may cause problems
■ Data must be coded in the barcode
■ In laser scanning, durability and cost are the two
disadvantages
