How CardScan Synchronizes with Your Windows CE Device (including Pocket PC handhelds) CardScan synchronizes with your Windows CE device using ActiveSync.  With the CardScan ActiveSync module you can automatically synchronize a CardScan file and your Windows CE contacts file so they contain identical information.  Using the CardScan ActiveSync module, you can scan and edit contacts then take the information with you on the road. If you change contact information in your Windows CE device, your CardScan file is updated automatically.
