Here's an example of what can be done with this....  It is a third-party offering which uses [older] tech developed by PrimeSense (acquired by Apple in 2013).

Aside from support for new hardware watchOS 5 will bring a Walkie Talkie app and native podcast support, including offline playback for both first- and third-party apps. 

@ Roger Fingas can you expand on the Walkie Talkie app... This could be a killer app for both personal and business use.

Mmm...

My 2014 iMac 5K has a 27" 5120 x 2880 display...

The company went on to note the activation of its donation service, allowing customers to contribute to ongoing Mercy Corps efforts through a dedicated button in iTunes and the App Store.

As usual, users can donate $5, $10, $25, $50, $100 or $200, with the full amount going directly to the humanitarian aid group.

Apple's efforts and intentions are appreciated -- its donation will, likely act as an incentive to people to donate to this cause or other causes of their choice.

However, I was unable to find the referenced donation service or buttons by visiting/searching iTunes or the App Store.  Eventually, I found the page by following the link in [original page of] this article --> Link to another AI Article --> Donation Button Link --> Mercy Corps Page in iTunes Store containing Donation Buttons.

This process appears to be a lot more opaque and involved than it needs to be.

Why couldn't Apple:

1. Setup a separate category in the App Store/iTunes for donations to special causes and charities 
2. Allow payment through ApplePay
3. Maybe even keep running totals ala GoFundMe
