Norman Joseph Woodland and Bernard Silver developed a bull鈥檚 eye style barcode as a part of university research project to develop an automated system to gather product information during checkout for a local food chain. Woodland drew inspiration from Morse code and movie soundtrack systems to invent modern barcodes.
David Collins, who worked in Sylvania, further developed the barcodes to address the problems faced in accurately tracking train cars. He developed a barcode with reflective stripes made from phosphorescent ink that can be easily read by light and pasted on train cars. Collins received several demands from various industries to launch a simpler version of his barcode to automate various business processes.
Middle Stage (1967 To 1970)
Collins, in 1967 quit Sylvania and founded Computer Identics. Later, he continued to work on automatic identification technology. He used black and white barcodes but the light source was replaced with a laser beam that scanned the barcodes from several feet away. The laser light source was smaller, cooler, and could move back and forth at faster rates over the barcodes and even read damaged or scratched barcodes.
