Requirements: The customer wanted one universal (iPhone/iPad) application which can scan QR and linear barcodes on different products and get up-to-date technical information. The application was required to have a convenient interface as well as the ability to download documentation in PDF, HTML, JPEG formats and store it on the device.

Challenge: The most complex issue was to implement barcode scanner which can recognize DataMatrix, QR and EAN13 barcodes. Additionally, the scanner had to be based on free APIs only.

Solution: Our developers spent much time to find a free solution, but no public scanner could decode all these types of barcodes. The iOS team combined two absolutely different APIs into one which has no analogs.

Results: The developed application provides the following functionality:

• Barcode recognition
• Asynchronous file downloading
• Storing files in a database
• PDF and HTML viewing

The application consists of the following sections:

• Main menu with top news (provides the ability to choose the type of scanner)
• History view (displays the last scanned MLFBs)
• Favorites view (displays projects and devices marked as favorite)
• Download view (shows downloading progress)
• PDF view
