 He says, restaurants are still using QR codes for menus. Often it's a pain chasing the little yellow box under the QR code in the iPhone's camera. There's a trick to make the scan happen in one step. First, you open settings on your iPhone, you scroll down to command center, scroll down to code scanner, and use the green plus to add it to your iPhone's control center. Now, no matter what you're doing, you can swipe down from the top right to pull up the command center on your phone and then tap the QR code box in an icon which opens up the code scanner, the code reader, and it jumps to whatever it reads. There's no chasing it around because it's not just happening inside the camera. It is literally happening in a bespoke code scanner app that is on your iPhone.
