Credit card processing App (with reader device)

We're looking to develop an App to process payments with credit card in iPhone and iPad. Similar to Square. The project will be split into phases. This is project only looks for the first phase. 1. Login on the main screen (like Paypal Here) 2. Dashboard with the info from the user (from regular database) 3. Screen to put amount and charge, getting the data from the credit card reader and sending it encrypted to the merchant. Connection with the merchant will be provided. 4. Screen with report of every transaction. Reference: Square
