3. Introduction
 A barcode is a Machine-Readable representation of data relating
to the object to which it is attached.
 Originally barcodes systematically represented data by varying
the widths and spacing's of parallel lines.
 One-dimensional (1D). Later two-dimensional (2D) codes.
 Combined with data-collection technology, bar codes provide a
rapid, accurate, and efficient.

4. History
 In 1948 Bernard Silver, a graduate student at Drexel Institute of
Technology in Philadelphia, Pennsylvania.
 Their first working system used ultraviolet ink, but the ink faded too
easily and was rather expensive.
 Woodland left Drexel, moved into his father's apartment in Florida, and
continued working on the system.
 Inspiration came from Morse code.
 On 20 October 1949 Woodland and Silver filed a patent.
 The patent was issued on 7 October 1952.

5. Working
 All Barcodes look similar at least when viewed from distance.
 95 numbers are grouped in 15 different sections.
 Okay now we have got the numbers, what do they actually mean?
 The very first number
 The First next 5 sets of numbers
 The Second next 5 sets of numbers
 Finally the final digit

7. Types Of Barcode Reader
 Pen Type reader

8.  CCD Reader

9.  Camera Reader

10. Advantages
 Barcode provide more accurate and rapid speed.
 It is time saving and store more information about product.
 It is easy to handling.
 It reduces the man power and saves time.
 It reduces the human errors and human efforts.
 Accuracy of data input.
 Real time data collection.

11. 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

12. Some More Applications
 Barcode is machine readable image so it store more data about product information.
 Provide the information of retail package, delivery warehousing and distribution of
product.
 It used at Shopping Mall bills, Book stalls.
 It used at food product and Electronic good purchasing.
 For Laboratories.
 For Libraries.
 For Industry.
