How does CardScan for Mac synchronization work?
CardScan for Mac can be set up to automatically sync to Address Book. In Preferences, select Synchronization and tell Address Book where your CardScan data file is located. Click OK. If your data file has a password, you will be prompted to enter it, and you may also be prompted to allow keychain access. Once you synchronize to Address Book, you can sync your iPhone, iPod, MobileMe or other software to Address Book to keep contacts identical across all your devices and applications.
