The Evolution of Barcode Systems

Barcodes are now seen in many places being used by various industries and businesses. Initially barcodes were used only for retail purposes. Later they emerged for use in many fields. As barcodes are accurate, easy to use, and provide uniform data collection and timely feedback, more and more businesses have started to use them to improve productivity and profitability. They are widely used in manufacturing, warehousing, shipping, retail, transportation and many other industries. Barcode technology is quite commonly used for asset management and tracking, healthcare, construction, and document management.

History of barcodes
The origin of barcode systems dates easypos back to 1932. Since then, many changes have taken place that have shaped the systems that are used currently.

Initial stages
The concept of barcodes was first started by Wallace Flint in 1932. He invented an automated checkout system for a grocery store using punched cards, which were placed in a reader. Inventory records were updated with this system.

Later in 1948, Bernard Silver along with his friend Norman Joseph Woodland researched a method that can automatically read product information. An ultraviolet light sensitive ink was used, which made patterns of ink that would glow under ultraviolet light. However, the method failed due to instability and expensive printing patterns.

In 1949, a patent was filed by them, titled as “Classifying Apparatus and Method.” A symbol made up of series of concentric circles was used by them. However, a description was given on the symbology of the current linear barcodes.

Following stages
In 1967, David J. Collins founded Computer Identics Corporation and developed a black and white barcode system read by a laser beam. This system was used for distribution, production, shipping, sorting, and other applications.

Later in 1967, one of the first scanning systems was installed by Radio Corporation of America (RCA) which used “bull’s eye” barcode symbols.

John F. Keidel invented the first commercially successful barcode reading system in 1969. The Universal Grocery Products Identification Code or UGPIC was developed in 1970. In 1970, barcodes were used for retail trade for the first time by Monarch Marking. The system was applied for industrial use for the first time by Plessey Telecommunications.

In the 1970’s, the US Supermarket Ad Hoc Committee of Uniform Grocery Product Code was established by The National Association of Food Chains (NAFC) which formulated a standardized 12-digit code. In 1973, the UGPIC was turned to Uniform Product Code (UPC) by George J. Laurer.

The first UPC barcode scanner was made in 1974 by NCR Corp. and was installed at Marsh’s supermarket in Troy. Wrigley’s chewing gum was the first product that was scanned by barcode scanner in the supermarket.
