I am interested in building a mobile payment application. The purpose of the application is for coffee shop customers to order their drink before arriving at the store. The user will set up a balance on the application through Paypal. The app will enable the user to order an item from a menu and also select a pickup time. The price of the item will be deducted from the Paypal balance and sent to the coffee shop's Paypal account. The order that is sent from the application will also have to be available for the workers in the store to see. This will enable them to ensure the coffee is ready at the designated pickup time.
I look forward to working with you on this application in the near future.
