Many industries, which need to process amounts of paper per day, like healthcare, finance, education and so on, are getting started to adopt Barcode scanning as the solution for the electronic document management system. For example, when you have a health examination, you will pick a form with some Barcode stickers. Once your health report generated, it is easy to track and record all relevant information. We can implement Barcode detection either on the client side or on the server side. Many client-side applications, especially mobile apps, tend to integrate Barcode functionality for shopping, boarding, social networking, logistics and so on. In contrast, some enterprise solutions, such as ECM (enterprise content management) system, need to detect Barcode on the server side while collecting various e-documents. In this post, I will demonstrate how to quickly build a Django barcode scanning app to load and scan document images via a Web page and detect barcode information on the server-side.
