Hi i need an application for ndraid or iphone ( it is the same for the moment in the futer i will need for both).
To use this app people have to register with facebook, tweeter..... accont
The app have to read a QrCode connect to a server and look if this code exist or not.
if it exist it have to read some records, understand if it is the first time or not and show some information.
if is the first time it have to save information about who is reading it, location, date time.
