Barcode system implementation

Barcode is the most popular resource for displaying information and subsequent shooting without using the keyboard. It is an essential element in the field of automatic identification.

 

In 1948, Bernard Silver was a graduate student at Drexel Institute of Technology in Philadelphia. A local food chain store owner had made an inquiry to the Drexel Institute asking about research into a method of automatically reading product information during checkout.

 

Woodland's first idea was to use ultraviolet light sensitive ink. The team built a working prototype but decided that the system was too unstable and expensive. They went back to the drawing board.

 

On October 20, 1949, Woodland and Silver filed their patent application for the "Classifying Apparatus and Method", describing their invention as "article classification...through the medium of identifying patterns". Bar code was first used commercially in 1966, however, it was soon realized that there would have to be some sort of industry standard set.

 

 

• Barcode efficiently displays data for automatic identification
• Lower cost of marking over other technologies
• Mobility, accuracy and speed reading
• You can reduce errors and costs and consequently increase profits
• Can be easily used wherever the need arises for automatic identification products.

 

 

About 200 bar code standards are define at this time, but commonly used are only few of them.

Some types of bar codes are associated with the use of standard. EAN/UPC - Are specified for retail Point-of-Sale (POS) because they are designed for the high volume scanning environment.
