How to Read a QR Code

Reading a QR code is relatively straightforward and requires just a few steps:

Step 1: Open the Camera App on Your Mobile Device

To read a QR code, you need a mobile device with a camera. Most smartphones come with a built-in camera app that can scan QR codes.

Step 2: Point the Camera at the QR Code

Tips and Tricks
