Need a Proof of Concept IPhone application that has the following functionality:
1. Simple shopping cart showing products from a database.
2. Allow user to add one or more items in to the shopping cart.
3. During the checkout, user will need to scan a barcode using the built in camera. Once the barcode is scanned it should be decrypted and the decrypted value should be submitted along with the shopping cart data.
4. The submitted order information will be saved in a database along with the barcode value. An email will be sent to a pre-defined email address with order confirmation.
5. The application should work through wireless network (user has a subscription to a wireless data plan) or when the user is connected to a wi-fi network
6. Preference will be given to bidders who can build this application without using any third part component (open source or licensed). Please mention that in your quote.
7. Since it is a Proof of Concept only, there is no need to create a back-end / admin panel. The look and feel should be kept very simple.
Please reply with example of only 2 of your best iPhone applications. If you have any question please feel free to ask.
