There's an easy way to transfer/sync your scanned cards between two different devices or app versions:
1) Open your 'Lite' app
2) Sign up for WebSync from within the app (if not registered)
3) Tap on 'Sync' icon at the bottom right corner and tap on 'Sync now'
3) Once complete, load up the 'Pro' app you'd like to sync to, and choose WebSync -> Sync your cards
4) Enter the same WebSync account details, and wait while the app downloads your saved cards
You can also edit and manage your cards from the web by logging in at http://www.scanbizcards.com/websync
Hope this helps, and thanks for choosing ScanBizCards!
