If every time you are scanning a new card to ABBYY BCR for iOS the SalesForce login message is shown - this may happen because the synchronization with Salesforce was selected in the Settings of the app.
In order to change it, please, do the following:
- Run ABBYY BCR for iOS;
- Go to Settings > Saving;
- Select CardHolder and Contacts (or another convenient option, that does not include SalesForce);
- Save the changes and try to scan the card again.
