Android credit card processing development - repost 2

I required a android mobile app that integrates a card reader and a PHP EPayment script. How the app should work will be like: [login to view URL] Here is the scope: 1- Read credit card data via a card reader ([login to view URL]) and android SDK for the card reader will be provided 2- Transmit CC data to a credit card processor ([login to view URL]) using their API which can be easily integrated: [login to view URL] If payment return as success, the mobile app will generate a receipt and able to sms to the customer and also need to call a API to store some data. 3- Other function include Transaction History/Search History, Account Settings. Account settings basically allows the app user to sync it's user/pass with a 3rd party php script as mentioned below Do note that this is only a prototype development and awarded programmer will have the opportunity to work on a long term project with us for a full scale mobile development project.
