I receive a lot of business cards and it's too tedious to manually enter them into Outlook. I nstread I use Corex Cardscan.
I quickly scan the cards using my own scanner. Using this application, it is much quicker to search for contacts than searching with Outlook.
If I need to mail contact, I copy and paste the address from Cardscan. If it's a regular contact I transfer the details to Outlook with a one click button in Cardscan.
Accuracy of OCR is about 80% but I find I only really need to correct errors when I need to pass the contact details onto someone else, or for a postal mailing list.
