Simple QR code iPhone App

a qr code that does the below function: Bowling Alley: Person walks in. They are given a QR code by an employee to scan. When they scan it pulls up a Facebook Check-In with a Post We have already composed on the back end. So what is happening in the backend is this: 1) Navigates to their Facebook page (which everyone is always signed into via their iphones.) 2) Accesses "Check-In" and finds the correct page for the business. (So Lucky Strike for example) 3) It then inserts a Facebook post such as "Having an awesome time at Lucky Strike! Like their page for a chance to win a pair of bowling shoes signed by Paris Hilton- at LUCKY STRIKE) So after the person scans the only thing that pops up for them is this Facebook post, checked in and ready to just post. All the work has been done for them. Let me know if you need me to clarify anything or explain in more detail. Only bid if you know how to do it?
