First you need a Live account (Microsoft)
Now log on to OneNote (or use the OneNote App on your phone or PC)
Create a new Notebook called "Business Card"
If you want to organize your business cards into groups, create a new section per group. I'm using a section for different projects and a section per exhibition I'm attending. I also have a "General" section for everything else.
Install Office Lens:
Connect Office Lens to your Live Account.
Use Office Lens to take a photo of the Business Card, using "Business Card" mode:
Now just press "Save" (Sorry for the danish text). Do NOT add additional images - this is not working.
You can change the name to something saying, but I always leave it as-is and then change it afterwards in OneNote.
Select the OneNote notebook and section you created previously.
Now you get to view a log with 2 new entries. Using this it is possible to open the new entry in OneNote, but also it is possible to open the actual contact information directly and import this to your contact list.
