The Faculty lecture was presented by Ms Mamta Kumari, Department of Mathematics and Statistics on September 22nd 2017. The topic for the lecture was Barcoding Technology. A barcode is an optical, machine-readable representation of data; the data usually describes something about the object that carries the barcode. Barcodes became commercially successful when they were used to automate supermarket checkout systems, a task for which they have become almost universal. Their use has spread to many other tasks that are generically referred to as automatic identification and data capture (AIDC). The very first scanning of the now ubiquitous Universal Product Code (UPC) barcode was on a pack of Wrigley Company chewing gum in June 1974. The main focus of the lecture was the mathematics behind the barcode technology; Ms. Mamta explained how barcodes are designed and how to read and interpret the barcodes.
