Who invented the barcode or bar code ?

i will tell you the full story of bar code and you decide who discovered this barcode. The first person which think about Bar Code called Max Badk ( Badc )in 1880 but he was not rich enough to complete this project so it become a dead idea for ( him ) but in 1932 Wallace Flint ( a man was finishing his postgraduate ) wrote a research about system for retail store ( automatic system ) in College of Business Administration , Harvard university. he explained how this system work and how to use it to manage the inventory and make the checkout process is too simple and easy. Also this system designed to control the move of the products ( in-out ) Shelf. but in this period USA was have much economic troubles ( not as 2008 economic troubles ) which affect on this new system so it failed for the second time. But in 1948 the idea become alive again by Bernard Silver ( he was graduated student from Drexel Institute of Technology ) , Joseph Woodland and Norman Johansen . they developed the idea and designed a system working by UV ink, and this system used by some store Chain in Philadelphia (is the largest city in Pennsylvania ). but the idea failed again because it cost much at this period .

you forget this name ” Joseph Woodland ” i referred to him in my last words, anyway this man work alone in developing this system till he made a Patent in 7 of October 1952 . i know it is long intro and you just want to know how barcode working OK let me tell you how.

to read bar code you should have something called scanner or barcode reader which send Laser beam on the bar code then this beam return again ( just white lines in barcode which reflect laser beam because black lines absorb it ) and this scanner ( barcode reader ) analyze this beams and convert the results into information . this informations send automatically into a PC ( computer ) which connected with this reader. this computer make identical operation with others codes which stored inside it. then this computer recognize the code then it store the new information like price, amount , product info in inventory ..etc.

where barcode or bar code scanner ( reader ) can be used ?

1. It used in tickets ( matches tickets, cinema, theater .. etc )
2. In booking offices like post office, flight tickets, train tickets or car rental
3. In Grocery stores and shops so we classified the products and inventory so it become ready for selling and pricing in easy way.
