Design an app mockup for a cafe mobile payment system

6 screen designs to be used for the build of an iPhone app. App concept: A mobile payment system providing a solution for 'split table billing' at cafes/bars & restaurants. The app would be free to download, users then register and link a credit/debit card to their account. Using QR code technology the table bill would appear on the customers mobile screen for them to 'select and pay' for the items they had. Look & Feel - The design needs to be bright and funky yet extremely simple. It is really important that the app is easy and quick to use. It will also need to be adapted to many food/drink menus. Screen 1 - Homescreen Screen 2 - 'Register'. Fields to include are cardholder name, email, card type, card number, expiry date, csv, register button Screen 3 - Screen to scan QR code Screen 4 - Example of table bill showing a likely breakfast bill for 3 people. a) Top of screen needs name of cafe e.g. 'Voyage cafe'. b) Item examples for bill - Eggs benedict $13.50, Bircher Muesli $10.00, Buttermilk Pancakes $12.00, Trim Latte $3.80, Large Cappuccino $3.80, English breakfast tea $4.50. c) Each item needs to be listed vertically with a selection box in the right column. d) Include the table bill total amount e) Need to show that screen can scroll I.e. large bills that won't appear on one screen. f) Include buttons for 'Pay All' 'Divide By' (option where you can select how many people to divide by) and 'Pay Now' button. Screen 5 - Shows items selected e.g. Eggs benedict and English breakfast tea. Illustrate 'Pay Now' button being selected. Screen 6 - Illustrate the payment processing Screen 7 - Show updated screen with items that have been paid for removed e.g. minus Eggs benedict and English breakfast tea. Bottom of screen needs the same options with one additional 'Pay balance at counter' I have attached a very rough mock-up. Mock-up does not include all screens required and is missing detail from the above brief. It has been included just to give a better understanding of the concept. I require professionally designed screens that can be used in presentations to demonstrate the idea and if needed could be used by a developer to cut up and build the app. I am welcome to suggestions to improve the flow and interface. I would like examples of related work with any bid received.
