What is QR Code?

A QR code (Quick Response code) is a type of two-dimensional barcode that stores information like text, URLs, contact details, or even other data in a compact and visually appealing way. The term “quick response” refers to the fast scanning capabilities of these codes.

Importance and Use Cases

QR codes have become increasingly popular due to their versatility and ease of use. Some common use cases include:

• Sharing business cards or personal contact information
• Saving product information, like prices or reviews, for later reference
• Accessing exclusive content, such as discounts or promo codes
• Providing additional information about a product or service

How to Scan a QR Code on iPhone

Step 1: Open the Camera App

To scan a QR code on your iPhone, you need to open the built-in camera app. You can do this by:

• Double-clicking the Home button (for devices with iOS 8 or later)
• Swiping up from the bottom of the screen and holding it (for devices with iOS 11 or later)

Step 2: Tap the Square Icon

At the top right corner of the camera viewfinder, you’ll see a small square icon. This is the QR code scanner.

• Tap this icon to enable the QR code scanning feature

Step 3: Focus on the QR Code

Point your iPhone’s camera at the QR code and make sure it’s in focus. You may need to adjust the viewfinder by tapping on the screen and dragging the square around the code until it’s centered.

• If the code is too dark or light, you can adjust the brightness by using the exposure control slider (represented by a sun icon) at the top right corner of the camera viewfinder

Step 4: Wait for the Code to Scan

The iPhone will automatically scan the QR code. You’ll see a loading animation and hear a brief beep when it successfully decodes the information.

• If the code is invalid or damaged, you might be prompted with an error message or taken to a website asking you to enter the URL manually

Step 5: Access the Scanned Content

Once the QR code has been scanned, you’ll see a notification pop-up on your screen. This notification will contain information about what was encoded in the QR code.

• For example, if it’s a URL, tapping “Open” will take you to that website directly

Tips and Tricks
