Barcodes are used in various industries to provide an optical, machine readable representation of data, usually related to an object they are placed on, such as a book, retail product, shipping package, or even the wrist of a patient in a hospital.
Recent developments in barcode technology include 2D codes that use shapes beyond the original bars (think of those QR codes you see on everything from magazine ads to cereal boxes). More significant, though, is the ability of smartphones and other mobile devices to scan barcodes using their built-in camera. Where in the past a specialized barcode scanner was required to read the coded information, now anyone can scan a code, greatly expanding the usefulness of barcodes for communicating data that can then be used a variety of ways.
Apps that can process barcode information are useful in a number of industries, and they can be used in apps that target workers as well as consumers. Let’s take a look at how easy it is to build an app that scans and processes barcodes in MobileTogether.
