Zac Hall, 9to5Mac:

Included in iOS 11.3 and macOS 10.13.4 is a new way to communicate with companies called Business Chat. Available in the United States as a beta to start, Business Chat lets you conveniently use iMessage for customer service and even complete transactions with Apple Pay. Check out our hands-on to see how it works.

I think Business Chat has huge potential. Zac does a nice job taking it through its paces. Key to success, as with Apple Pay, is adoption.
