We need an app with two secrions.
In one feature it use camera for ocr of any text on a coupon ....and search on a website information about it. Informations taken from this site will be real-time data from a xml feed (like financial data).
This digitalized coupons can be saved in the profile of the user.
In an other section of the app we will give some news/information to the user
The app is alwayse syncronized with a website.
Each user can log in through the credentials of a mother-website (wordpress), and according to the level of authorization may or may not use the app to realtime ocr datafeed, see or not see the news/infos
A new user can sign-in through fb/g+ account but all this info must be reported to the mother-website.
