Looking for a simple paid application that will be posted on App Store, where it is functionality as the following
1) Download the paid application
2) Automatically set the expiry date to T+3 days
2) from a server access, fill certain text value and send a push notification message to all apps users
3) Getting a message is only valid for users,who still didn't reach the expiry date
4) After T+3 day (means after expiry), the user can have an option to do a payment and to renew the expiry date for another X days, where amount is calculated based on number of days , alternatively user may re-install the apps and install it again from the market
5) as a response, I like to know the mobile payment approach proposed, for accepting card payments/other payments
