The System is based on uploading and processing vCards.
The only thing a user has to do, is creating his own vCard ONCE.
This vCard can be used everlasting.
Providers must implement a small peace of software for processing vCards and has to offer this special vCard upload feature.
Doing so, the provider can send a prefilled form to the user, so users keep hold of full data control.
Now a user can send the filled form to the provider in such kind, as if he has typed in the data manually!
This procedure is done in a few seconds naturally!
