Funny Holidays - Barcode Birthday

Linear coding technology, which made it possible to identify products, appeared thanks to IBM in 1973 The introduction of barcodes marked the beginning of the automation of trade processes, which speeded up the process of serving customers For the first time, linear symbols were applied to the packaging of chewing gum in 1974, although the process of creating the code began in 1948 Authorship of one of the most advanced inventions of the twentieth century owned by Bernard Silver and Norman Joseph Woodland On April 3, 1973, IBM officially introduced the development of the UPC (Universal Product Code) to the world This date is considered the barcode's birthday The first keys, providing information about the product to both consumers and sellers, were round in shape Thin and wide lines were connected into a circle, which reduced the likelihood of errors when reading barcodes pasted on the product label American inventors from IBM took Morse code and the technology of encrypting sounds for movies as the basis for linear symbolism After B Silver and N Woodland came up with the barcode in 1949, they began to develop the design of the scanner The first model was quite bulky and bore little resemblance to modern devices Scanners for decoding linear coding technology began to be produced on an industrial scale only in the late 1960s after the advent of computers and lasers Before barcodes, punch cards were used to label goods However, the cards were not very convenient to use, and the machines for reading information from them were expensive and gigantic in size The scanning machine for barcodes, first demonstrated in 1971 at the summit of major US trade figures, aroused the interest and approval of its participants The development of UPC has quickly become a universal linear symbol used by manufacturers, exporters and sellers of goods in many countries around the world IBM's barcode competes with symbols in which information is encrypted using dots, squares and other shapes However, it was UPC that was recognized in 1973 by participants in a convention of representatives of US retail chains as the standard for labeling goods In Europe, this coding system is called European Article Numbering and has been used since 1977 Today, a barcode, consisting of a sequence of black stripes of different widths, is used to mark both goods and tickets, letters, documents, etc UPC, or more precisely, its EAN-13 variety with numbers under the symbols, is applied to 80% of manufactured products worldwide products Therefore, establishing the date and celebrating the birthday of the barcode on April 3 is completely justified, because without this invention the life of a modern person would not be so comfortable
