The system will be integrated into a Retailer Point of Sale (POS) cash register.
The Cashier will be prompted during the items ring-up whether to send the customer's receipt via mobile phone or email. The receipt could be converted to a PDF or an image prior to submittal to a storage area (file server) and a copy sent to the customer simultaneously.
Alternatively, the receipt goes out from the Retailer POS as an XML file to database storage. This file will be identified by a "Tag" number to the database. The tag number will comprise of the Customer's mobile phone number and/or email address.
Database application will send SMS to mobile phone using either the phone number or email.
Create a demo or prototype of the application using C# or VC++ or Java. Database can be either MySQL or MSSQL or MS Access.
