QR Scanner - Native iPhone application

Hi, We are looking for a QR scanner/reader native iPhone application. The app needs to include the standard features (SMS, Address book, etc...) All links will open in an in-app browser with an option to integrate ads at the bottom of the page (we would like to be able to control it remotely). This should be a simple app that performs an action immediately when a QR is scanned. We would also like to have a link on a website that has been opened in the in-app browser that will let the user save contact details to his iPhone. Thanks
