Or getting your restaurant bill with a printed QR code and paying right there by scanning the deep link into Messenger

Paying through QR codes can work, because (1) how easy it is to start the iPhone camera and (2) everyone is on Facebook Messenger/WhatsApp

Think about QR codes as hyperlinks for the physical world

Just like iOS knowing what to do if you tap a link, iOS 11 will know what to do if you scan a code. It moves QR from app to platform level.

Till now, the information "hyperlinks for the physical world" could transmit was limited to what people could read and remember.

It is interesting from a risk perspective how this will go. You can send all kinds of info in the QR code.

What would be the attack angle? Putting nefarious QR codes in legitimate places so you route unsuspecting users to the wrong website?

Phishing to a page which looks identical to the theater your visiting for example.

Seems relatively small risk. A person buys tickets, goes to the door, gets rejected, loudly complains, and points out bad code.
Loading seems to be taking a while.
