How can I scan a barcode that’s on my iPhone?

Icky,

Thanks for those additional details.

To scan a QR code that you received in an email, you can either view the email on another device and use the camera on your iPhone to scan it from that screen, or you can print the email: Print and email or attachment in Mail on iPhone

Cheers!

Hi there,

We understand you're trying to read a QR code on your iPhone SE.

It looks like you've already reviewed Scan a QR code with your iPhone, iPad, or iPod touch.

Specifically, check out the detail below:

"Select the rear facing camera. Hold your device so that the QR code appears in the viewfinder in the Camera app. Your device recognizes the QR code and shows a notification."

The QR code would need to be viewable by the camera on your device in order to access the associated link.

We hope this helps.

We're glad to hear those resources and steps have been helpful.

Feel free to post again if you have any questions in the future.

Take care!
