2. • A barcode (also bar code) is a machine-readable
representation of information
• Barcodes can be read by optical scanners called barcode
readers or scanned from an image by special software.for
eg RS-232 barcode scanner, Keyboard interface scanners,
USB scanners
• Barcodes are widely used to implement Auto ID Data
Capture (AIDC) systems that improve the speed and
accuracy of computer data entry.
Barcoding
3. WHY BARCODES ?
* To enable data capture
- For 100% accuracy and high speed.
- Generation of automated billing, packing
lists, delivery challans etc.
- Effective product track & trace
4. Barcode types
There are two types of barcodes: Linear
barcodes and 2D barcodes. Some examples
include:
Linear barcodes 2D barcodes
Code 128 Data Matrix
UPC Dot code
Interleaved 2 of 5 QR code
6. Universal Product Code: Built
in Checks
• Check Digit Calculation: Example
o Sum odd digits (1, 3, 5..)
• 6+9+8+0+0+9 = 32
o Multiply this by 3
• 32*3 = 96
o Sum even digits (2, 4, 6..)
• 3+3+2+0+3 = 11
o Add this to value in Step 2
• 96+11 = 107
o Determine then number that added to the above
value would generate a multiple of 10
• 107 + 3 = 110
• Therefore 3 is our Check Digit
7. QR code (abbreviated from Quick Response Code) is a
type of matrix barcode (or two-dimensional barcode) first
designed for the automotive industry in Japan.
The QR Code system has become popular outside
the automotive industry due to its fast readability
and greater storage capacity compared to standard
UPC barcodes.
Applications include product tracking, item
identification, time tracking, document
management, general marketing, and much more

HOW TO READ BAR CODES
13. - Distribution (Product track and trace, information flow)
- Manufacturing (Inventory control, raw material procurement, work-
in-progress, dynamic production scheduling)
- Customer Satisfaction (Low product prices, quick replenishment,
faster checkouts)
- Exports
- In line with buyers requirements
- Product track and trace
Applications
14. Usage of Barcoding in India – current status
•Automobile Industry–for inventory management/ track &
trace/production scheduling.
•Readymade garments Industry – for inventory
management/track & trace/production scheduling.
•Pharmaceutical Industry – for inventory management / track &
trace/production scheduling.
•Retail Industry – Grocery, etc.
•Exports (on buyers directives)
•Healthcare (hospitals etc)
15. .
The example production line seen below has been simplified. This
production line is for the assembly of a bicycle. As the bicycle frame
travels down the production line each person at a workstation
workstation has a specific task to carry out ( see below). Each
component/part has a barcode, ensuring the computer system can
keep track of the products progress, along the production line.
16. Retailers / shops / catalogues. A checkout operator in a supermarket scans a product
barcode as the customer passes through the checkouts. The price will be automatically
displayed and as more products are checked out the total cost will be calculated. This
means the checkout operator does not need to manually type in the price of each
product. This makes the checkout procedure less time consuming and it is less likely
that mistakes will happen.
17. Advantages of barcode
• Speed and accuracy
• Barcodes promote better decision making.
• System costs are lower than other means of data entry
because of the existence of interfacing hardware and
software.
• Barcode systems create value not only by saving time, but
also by preventing costly errors.
• Using a barcode system reduces employee training time.
It takes only minutes to master the hand-held scanner for
reading barcodes.
• Barcodes are inexpensive to design and print
• Data obtained through barcodes is available rapidly.
18. disadvantages of barcode
• Data must be coded in barcode
• They are very labour intensive; as they must be
scanned individually.
• If a barcode is damaged there is no way to scan the
product.
• Scanning Problems
20. What is RFID?
• RFID stands for Radio-frequency identification (RFID ) an
Auto-ID data collection.
• It is an automatic identification method, relying on storing and
remotely retrieving data using devices called RFID tags or
transponders.
• Is fast and does not require physical sight or contact between
reader/scanner and the tagged item.
• invented in 1948 by Harry Stockman.
• Initial application was during World War II
21. Working
• A radio device called a tag is attached to the object that needs
to be identified.
• When this tagged object is presented in front of a suitable
RFID reader, the tag transmits this data to the reader (via the
reader antenna).
• The reader then reads the data and has the capability to
forward it over suitable communication channels.
• This application can then use this unique data to identify the
object presented to the reader.
