What is a QR code?

They can contain various data types, including text, URLs, contact details, Wi-Fi access credentials, etc.

How to Launch the QR Code Reader App
You need to download and install a QR code scanning app on your phone and locate its icon on the home tab or in your app drawer. Tap on it to launch it. After launching, you typically see a simple interface with a camera preview and a scanning frame.
Position the QR Code in the frame.
When using a QR code reader, it's crucial to position the QR code properly within the scanning frame. Ensure the QR code is fully visible and properly aligned with the frame. Full visibility of the QR code helps the app recognize and scan the QR code accurately, reducing errors or failed scans.
Scanning the QR Code

Keep your phone steady and allow the app to focus and capture the QR code. Depending on the QR Code reader application, you may see a visual indication or beep sound confirming a successful scan.
Interpreting the scanned QR Code
After successfully scanning a QR code, the QR code reader app will present the decoded information on your phone's screen. This information can vary widely, depending on the type of QR code scanned. It may include website URLs, contact details, text messages, email addresses, or calendar events. Take a moment to review the information displayed.
Taking Action Based on QR Code Content
Once you've interpreted the information from the scanned QR code, you can take appropriate actions based on the content. For example, if the QR code leads to a website URL, tapping the displayed link will open the website in your phone's browser. Similarly, if the QR code contains contact details, save them to your phone's address book.
