I would like to commission the development of a small mobile phone application that lets users send their business card after making a phone call to another user. The premise is simple, when a user makes a call, upon ending the call the recipient should receive a business card from the caller. The business card will include details such as; 1. Full Name 2. Postal Address 3. Work Address 3. Email Address(es) 4. Contact number(s) 5. Facebook, MSN, AIM IDs The caller can configure which fields are private and can be selectively sent to a recipient. Once the recipient receives the business card, it should populate a new contact within the phone address book with all the provided business card details. The links in the business card should have hotlinks so you can click on an email address for e.g. which would then create a new email message. To stop unsolicited spam being sent to the recipient the receiver must have the ability to either accept or decline any business cards being sent. The recipient must also be aware that they have opted into using the business card application. Likewise the sender can determine what information they want to send to a particular recipient or can turn off the app at any time. This app needs to be compatible with the windows zune marketplace, android marketplace and Apple app store and all its related mobile devices. I am open to suggestions on its design and functionality.
