Book retailer Barnes and Noble has added Apple Business Chat. This lets Apple customers connect to businesses through iMessage (via Appleosophy).
It’s not immediately obvious when a store adds Business Chat, but one way to find out is through Apple Maps. If you search for a business and it gives you the option to message it, that means it supports Business Chat.
Since iMessage is end-to-end encrypted, your conversations with the business will stay private between the two parties. You also won’t see advertising within the app, unlike rival Facebook Messenger’s business communication feature.
