The client had a similar idea to improve shopping experience with a mobile application which allows shoppers see deals that are nearby. The client have been working hard to make finding great deals easier for shoppers. The key to making the clients vision a reality was to approach Sigma Infosolutions.

  • QR code scanning libraries were not available and working consistently in all versions of Android SDK and iOS. We customized the QR code scanning library(ZXing) so that the behavior of QR scanning is same across Android and iOS and also covering maximum number of devices in the fragmented market.
  • The architecture had an issue with facebook and its SSO integration to maximize user experience. It is always possible that the user had already installed the facabook app in their mobile and if that is the case, when the user uses the app; the SSO reads the status of the user and does not ask the user to login again. The facebook mobile SSO integration was done for both Android and iOS
  • Rendering the UI dynamically for displaying badges was a challenge for catering devices of several  platforms and resolutions. The badges count and the shape/size of the badge will vary dynamically based on the user’s check-in patters in his/her favorite shop. Customized algorithm and controllers were written to handle these.

The customer from the beginning was expecting pixel perfection in all the screens. The start-up logic and screens were customized based on the way the user is using the app. If the user just taps the NFC phone against a NFC card, the app will launch and take the user to a customized flow compared to the generic login flow.


Sigma Infosolutions’ mobile development team successfully compiled the architecture required for the project and followed waterfall model ensuring that the integration of the system proceeds along with user testing.
