I have used Cardscan for years, and it is the repository for all my business and personal contacts. I have 3 Cardscan business card scanners, one for my office desktop, my home desktop, and my laptop computers. Keeping the contacts sychronized with At Your Service is simple, reliable, and worry free. The browser interface has been very handy on ocassion. For example, when my mother passed away, I accessed important information regarding family contacts at the funeral parlor turning a potential problem into a simple solution when I borrowed the Funeral Parlor's computer/browser to access At Your Service.
I also have never had virus problems associated with Outlook contacts or Microsoft email problems. I rest assured knowing I can always access my contacts, regardless of the state of my email systems or other issues and from anywhere I can access a browser. Plus you get all the advantages of Cardscan business card scanning and contact management.
I could not recommend this product highly enough!
In fact I have to many of my friends and colleagues.
