![]() It consists of two parts – the vertical black and white stripes (barcode) and a 12 digit UPC number. Most of the products have a linear barcode and is easy to recognize visually. HOW DO BARCODE SCANNERS WORK? Barcode is of two types – Linear and 2D. The initial invention included the use of Morse Code, thus, giving rise to ‘Linear barcode system.’ Later, the linear system was replaced by circular rings and was known as ‘Bulls-eye system.’ Technological advances brought innovations in barcode scanners and, in 1973, barcode developed by George Laurer was widely accepted for its simplicity and power to hold more information. When the question ‘how to automatically read product information?’ arisen Silver, along with his friends, experimented with various potential solutions. Barcode Scanners THE ORIGIN OF BARCODE SYSTEM The idea for modern Barcode system originated back in 1948 in the mind of a graduate student Bernard Silver from Drexel Institute of Technology, Philadelphia.
