BIZ App
Take a photo of a business card: the contact goes into your protected address book and receives your digital card with a request for consent.
It is called the BIZ App. The BIZ App lets you photograph a business card and send it to the Klinik Sankt Moritz server, which recognises it as yours. Then it does some very simple things. It saves the information and automatically emails your details to the person who gave you the card, in a file they can add to their contacts with one click.
It contains everything; whatever you want is already inside. And of course it includes the request to sign up for the authenticated newsletter.
