Scan QR codes with a Mac document camera (Vizo)

Scan › QR / Barcode reads a code in the camera view and returns the result. It is not a full-page Document scan, not Card, and not OCR for a paragraph of print. A normal camera works for most codes on paper or on a phone screen.

Read the code

Connect the camera and open Vizo. Allow Camera when asked.
Point the camera at the code. Hold still so the code fills enough of the frame to read clearly.
Open Scan and choose QR / Barcode.
Choose QR or Barcode for the kind of mark you have.
Wait for the read result, then copy it or open it as the app allows.

If the read fails, move closer, flatten the paper, or reduce glare on a glossy label. Try again after the code is sharp in the preview. A damaged or half-covered mark may never read — print or display a clearer copy. Saving the whole worksheet as a file is Document or Snapshot — use those modes when you need the page image, not only the code payload.

Install Vizo from this website. macOS 11.5 or later.
