WHERE CAN I RETRIEVE MY SCANNED QR CODES?

Scanned QR codes are not saved by the Camera app, unless the user also took a picture of the QR code.

If referring to COVID-19 vaccination QR codes, look in the Wallet app on your iPhone, and in Health app.

An add-on scanning app can provide features which the built-in Camera app doesn’t.

How to retrieve your scan?

I’d like to know how to retrieve a QR scan, after you’ve scanned the QR of your photos.
