In 1948 a graduate student overheard an important executive of a food chain entreating the dean of the school to start a research project aimed at capturing product information automatically at the checkout counter. The dean turned down the research project but the graduate student could not forget about overhearing this discussion.
He took this idea to his friend who started to work on concepts and came up with utilizing patterns of ink that would glow under ultraviolent light. This idea, although very well thought out, had a number of disadvantages and did not finish up fitting the requirements of most retailers.
The graduate student continued to work on the procedure of building a system that could capture product information. Initial problems with this technique consisted of factors like high printing prices, large massive equipment, and heat from the very bright light bulbs that were first used while trying to create barcode scanners. These would actually burn the paper the bar codes were printed on.
These first bar code systems were extremely expensive and so not many stores could afford to put this new technology in their stores. Today's bar-coding systems have grown to the point where bar codes printed onto packaging are small and scanners which read them are hand-held. This equipment is extremely affordable and is used in almost all stores and restaurants or other places of business. Bar codes have changed the way we do business nowadays.
Having a system that could easily keep a record of purchases and inventory makes it easy for store owners to identify when they need to order more inventory and how much inventory to order. They can easily keep an record of what products customers are purchasing and what is not selling so well. Bar codes also make business much faster. Retailers no longer have to manually enter inventory in.
Computers running barcode software could keep track of everything automatically using the bar codes that are scanned into large databases. Purchasing goods is also faster. There is no requirement for a cashier in many cases to look up a product or have to manually enter the price. The cashier can simply use a bar code scanner and just scan your product in.
This merely takes a few seconds and then she could take your money and check you out. Company could serve more customers this way. Having the pricing information mechanically tracked by bar codes has also eliminated the countless hours of bookkeeping that merchants used to have to do by hand.
Manufacturers and retailers could now do more in a day than they would have been capable to without the invention of the bar coding system. The bar code system has enhanced the way we do business and enables us to operate businesses more accurately than we could before.
How Did Bar Code Scanning Develop And Why Is This Type Of System So Important?
You can find a bar code on just about anything you purchase these days. Bar code technology has become an important part of everyday life. But how did bar codes develop and why is this technology so important?
