1.1 History

As kept in the patent documentation, Norm Woodland and Bernard Silver developed a full scope of scanner tag images in 1949 (Online Barcode Tutorial, 2005). Prior to that, no standardized identification innovation had been recorded and placed into useful application. Around then, Bernard Silver was only an alumni at Drexel Institute of Technology in Philadelphia. As per Bellis (2009), the proprietor of a nearby pecking order shop asked the Drexel Institute to explore a technique to consequently peruse data of products like cost and date during checkout. Because of this enquiry, Bernard Silver fostered an answer with Woodland utilizing bright touchy ink (Bar Code 1, 2009).
