I need an ASP.net website for mobile devices (would like to keep it device independent if possible) to scan a barcode using the devices onboard camera, to update a SQL database. The pages need to be simple with fast response. This site will be only be accessible behind our firewall. The site will simply track the start and stop of jobs and will take input for quantities etc. I have attached a sample mockup drawing of screens. Please note the pages are scanned in reverse order.
