Barcode scanner app

barcode scanner app We sell sunglasses, reading glasses, etc. to gasolin stations and supermarkets, For reordering purpose for the store to use itself, or for our sales reps, we need to be able to: 1. login by writing the store name, adress, customer number, etc. 2. scan with the iphone - first select number of units (1 by default) 3. the app must be able to identify the product (we can provide a database with all barcodes and listed products) and add all together in a list at the app (like a shopping basket) 4. send the order by email to a default email adress, or they can write a different email adress. Later on - or if possible now? - we would like to have integration with our Dynamics Nav system
