Now that you know the importance of QR codes, let’s dive into the step-by-step guide:

Step 1: Installing a QR Code Scanner App

You’ll need a dedicated app to scan QR codes. Some popular options include:

• Google Lens (pre-installed on many Android devices)

1. Point the camera at the QR code: Hold your Android device above the QR code, making sure it’s in focus.
2. Adjust the camera settings (if necessary): If the QR code is not being detected, try adjusting the camera settings or moving the phone slightly to get a better reading.
3. Wait for the app to recognize the QR code: Depending on the quality of the scan and your device’s processing power, this might take just a few seconds.
4. Tap “Save” or “Open” (if prompted): If the scanned QR code contains information like URLs or text, you’ll be presented with options to save or open it.
