2. What is Barcode?

Barcodes are simply a set of symbols used to
represent alpha-numeric information instead of
seeing a number“1”, or letter “A”, you would see a
series of black and white bars in various
combinations and in different widths.

These are used to encode data. The data encoded in
such bars can be decoded again to represent it in
human readable form.

3. Brief History

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.

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.

4. Why use Barcodes?

When barcodes are used in the business process,
procedures are automated to increase productivity
and reduce human error.

Whenever there is a need to accurately identify or
track something, bar-coding should be used. For
example, in a data entry work environment, workers
may be required to enter an enormous amount of
data into a customer database system.

Instead of manually typing a customer identification
number into a database, if the information is
contained in a barcode, a data entry operator may
scan it in. This would increase automation and

5. Barcode types and use

The type of barcode to use for a particular situation
depends upon:
1) The use.
2) The data encoded in the barcode.
3) How the barcode will be printed.

6. There are two types of barcodes:

Linear barcodes

2D barcodes.

7. Applications of Barcode

RETAIL APPLICATIONS
− Super markets
− Counter-mounted Bar Code scanners
− Universal Product Code (UPC)
− Price and description information

WARE HOUSING

HEALTH CARE APPLICATIONS
− Drugs, devices, instruments
− Identification of expiry date

8. Evaluation of Barcode

One of the most common tools for reading barcodes
is the hand held barcode scanner. All of the barcode
scanners recommended and sold by ID Automation
have built-in decoders that can read several different
bar code types.

Most of the scanners sold by ID Automation receive
their power from the PC keyboard or USB port so
no external power supply is required. When a
barcode is scanned, the data is sent to the PC as if it
was typed using a keyboard.

9. 1D Barcode

How 1D Barcode Works

UPC Code: Universal Product
Code (UPC), which is used
on grocery items to encode
a 10 digit number.

15. 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

16. Future of Barcode Technology

Age verification

Opening customer accounts:

Business Tracking

Product Stock control

Coupons

Fraud detection

17. QR Code

QR codes are two-dimensional bar
codes that can contain any
alphanumeric text and often
feature URLs that direct users to
sites Product Stock control

19. How QR code works
 QR Code just store the address
 Every Square have meaning in QR code

20. Conclusion
Barcodes are moving to new technology. That will
expand the job market.
