Flow business card view is a feature that shows enterprise contact information even if it is not stored in your mobile phone contact (unknown number!) when a call is received. Business card view only works with Android apps, not with iPhone apps.
Business card information shows the enterprise contacts that I have stored in my Contacts app. This will be automatically recommended and added to the contact via flow communication history, which will appear as business cards (Of course, you can register your own contacts.). First, run the "Contact" app on Bizplay!
