How to Scan QR Codes Instantly on iPhone

Option 1: Built-in Camera

  • Open your camera
  • Point it at a QR code

It works, but sometimes it can be slow or inconsistent.

Option 2: Use a Dedicated QR App (Recommended)

A dedicated app makes scanning much faster and smoother.

Here’s how:

  1. Open your QR code app
  2. Select “Create QR Code”
  3. Add your content (URL, PDF, text, etc.)
  4. Generate and share immediately
