Who were the parents of the barcode?
They say that necessity is the mother of invention, and thus it was with the bar code. Hearing request a local dealer for a quick method to read the information system of product in the box, graduate student and his friend Bernard Silver, Norman Woodland, began work on a number of systems. Silver can be unaware that another inventor had developed a system using punch cards back in 1930. This system never gelled due to the prohibitive costs and equipment of the Great Depression.
The silver medal went to encouraged by the problem, he continued to pursue without funding. The first system developed and used ultraviolet ink wooded areas, but proved too expensive and unreliable, as the ink is faded. He was inspired then by the Morse code and later claimed design bar code that was created first in the sand of Florida. Just extended the dots and dashes of the code Morse to create what would later become the design of bar codes.
Then use the technology developed for soundtracks film to read it, but was moved to change the design of the box to a target that can be read in any direction. In 1949, the couple asked received a patent in 1952. Silver began working for IBM in 1951, which was, ironically, deeply involved in punch-card technology. Silver tried to interest the corporate giant in your project, and IBM actually commissioned a report which indicated that the idea was feasible, but the technology involved was simply not available at that time.
It did not help the reading device of all paper prototype burning well, but did not work. However, the report showed IBM accurate, as the 500 watt incandescent light bulb was just too much, the prototype was too large, and the technology necessary to reduce either not available in 1950. While IBM offered to buy the patent for a lot less than it was, Silver and Woodland persevered. In 1962, Philco purchased but unfortunately died Bernard Silver in a car crash the following year.
Meanwhile, supermarkets were trying to maintain the correct amount of inventory, the railroads only were trying to track their cars. The railway industry is still very strong in those days, adopted a similar system to the bar code, developed by David Collins and signed by Sylvania. Collins tried to interest Sylvania, a smaller version of the system, which could be used in anything but Sylvania refused, so they quit and team co-founder IDentics Corporation. In the meantime, Philco sold the patent rights of bar code to RCA.
Development began in earnest in the late 1960s, as the food industry is now demanding that technology. Collins Computing silence IDentics barcode rudimentary facilities, built by hand and scanning systems at a General Motors (GM) plants in Michigan, and General Trading Company in New Jersey. Kroger offered to test the laser-guided RCA system was developing. In the 1970s, the limited success on RCA, with its target barcode caught the attention of, you guessed IBM, which hit an employee, Norman's own forests, to manage the project. The rest, they say, is history.
