You can export business cards from ABBYY BCR for Android and iOS to Salesforce if you use one of the following license editions with API Access:

• Enterprise Edition,
• Unlimited Edition,
• Developer Edition,
• Performance Edition,
• Professional Edition*

* Professional Edition is edition with no API Access by default. For Professional Edition organizations, all requests for API access must be purchased and can be processed contacting your Account Executive.

In case you have Salesforce license type which is not in the list it is not possible to set ABBYY BCR export with this license type.
