BARCODE INFOMATION SECTION THREE

Oct 11, 2018

With handheld laser scanners and barcodes, users can perform product searches, speed ticket check-in, track mail, and encode patient medical information. In fact, bar codes have been widely used in the global transportation, industrial and logistics industries.

Susan Woodland said her father and co-inventor Bernard Silver was a graduate student at a engineering school in Philadelphia, the current school of Drexel. The predecessor of the university. Schiffer occasionally heard that a supermarket executive asked the school principal to assign engineering students to study a way to search for goods more efficiently at the supermarket checkout counter.

Susan Woodland said: "My father likes to study interesting questions." Norman Woodland designed a code based on the Moss code and applied for the world with Schiffer in 1949. A barcode patent. Norman Woodland joined IBM in 1951 and the two obtained the patent in 1952.

IBM said in a notice that it was not until more than 20 years after the patent application that appropriate laser technology emerged, making the barcode commercially viable. According to the American Inventors Hall of Fame, Schiffer died in 1963. Schiffer and Norman Woodland entered the American Inventors Hall of Fame in 2011.

Susan Woodland said: "In a sense, this technology took so long to get applied, which disappointed my father."

According to IBM, the world's first scan of barcodes took place on June 26, 1974 in Troy, Ohio. At the time, a cashier scanned 10 packs of Wrigley gum for shopper Clyde Dawson for 67 cents. This marks the birth of bar code technology.

In the late 1970s, Norman Woodland was excited about the commercial use of barcodes. Susan Woodland said: "My father is a friendly person. He is very excited about inventing barcodes. He likes to talk to supermarket cashiers and ask them what they think about barcode scanners. What are the problems and what they want? Improvement.” Norman Woodland has been trying to make barcode technology perfect.

Susan Woodland said: "He participated in the design of the entire system, including the user's standing style, the height of the laser scanner, and how to protect people's eyes from laser damage. He is a perfectionist." Man Woodland is also a historian studying the American atomic bomb "Manhattan Project." However, Susan Woodland believes that he pays more attention to the invention of bar codes.
