Lead Registration App aims to serve as an offline database (no WiFi or Internet connection required) to capture Registration details at events such as "Open House" , "Door-to-Door Sales/Survey" and other such Campaigns.
The App provides a "kiosk" mode where a user can only Register but not see the entire list (controlled via Settings).
The list of Registrants can be exported as an xml / txt file.
When the xml / txt file is eMailed to an Application that has an "eMail Service" end point , this list can be added to a Database for use in subsequent Business processes.
(example : an SF.com eMail Service can parse the file with the List of Accounts / Leads and add it to Leads / Custom Object)
A free eMail Handler for Salesforce.com is available and can be installed in your SF.com instance. Please visit support page for details and link to the free SF.com eMail handler package.
