QR code

QR code, or QR code reader?

The reader is your camera, as per this support article:--> Scan a QR code with your iPhone, iPad, or iPod touch - Apple Support

Should be the former, please specify what QR code you're talking about.

if you need to read a QR code using the phone you can turn on the camera and focus on the QR code and it should work from there.

if you're looking to do something else let us know what that it.

When asking where the QR code is on an iPhone or other device, I think people are asking if the actual device has a QR code.

I've just had the same issue - I've downloaded Signal (messenger app) on my phone, and if I want to link my MacBook Air to it, it wants me to scan the QR code of my MacBook Air.

Do Mac devices have their own unique QR code at all?
