I will try to explain in few words my idea:
First of all, it is a marketing tool for all business who dont know how to expose their products in the internet and social midias.
"Descont" (i think this will be the name).
Summary: It will be an interface between an establishment and a customer. The property (eg a bar) creates within this app advertising for costumer as an example "Post a picture through the app with check in showing the front of the bar, share it with your friends on a social network (facebook, etc ...) and win this same day a beer". Later, the customer enter the bar, take the picture and put it in this application that was choosen to share on Facebook with check in. The app with his "expert", recognizes the registration of the property at the check in at the photo of the person, creates a list for the establishment of the person who posted. Futhermore, the photo of the customer will appear in Facebook like this (- Customer "A" posted a photo by "Descont" application and won a beer on the "Y" bar -). At the end, the owner of the bar is happy because the app spread his name and his advertising to friends of customer "A" that can multiply by sharing, "A" is also happy because he won a beer for one photo (that is already normal, but without a free beer). And how do I earn money? Charge a fee for establishing by the picture posted, I don't know it exactly, but is about 50 cents. This marketing tool, in this example will cost 50 cents for sharing the bar to 500+ friends that customer has in the social midia.
Any doubt please contact me.
Please, see if is possible to do this, and how much it will cost.
I want for IOS and Android System.
