Contacts are exported from the WindowsPhone with ExportContacts. The contacts are sent to a WebService. The WebService stores the contacts in a CSV-, XML-, vCard- or QRCode- file and sends them to the registered email address. The app producer operates such a 'public WebService' that can be used free of charge. For this, a data connection is required.
