This is not only an application, this is just a supper efficient tool to scan and generate QR or Barcode scanner. It scans perfectly almost every time smoothly. I has a simple, straightforward, apparently great user interface to interact with its features. We represented three major feature; Scanner, Generator and Result History with a Bottom Navigator. It has increased usability a lot.
