What is a QR Code?

A Quick Response (QR) code is a type of two-dimensional barcode that stores information in a matrix of black and white squares. It was first introduced in 1994 by Denso Wave, a Japanese company, and has since become a widely used technology for encoding data such as URLs, text, contact information, and more.

Importance and Use Cases

QR codes have numerous applications across various industries:

• Marketing: QR codes are often used to drive traffic to websites, social media pages, or landing pages.
• Contactless Payments: Many retailers use QR code-based payment systems for seamless transactions.
• Healthcare: QR codes are employed in healthcare for tracking prescriptions, medical records, and more.
• Travel: QR codes enable travelers to access travel documents, boarding passes, and itineraries.

Scanning a QR Code on Android

Scanning a QR code on your Android phone is a straightforward process. Here’s how:

Step 1: Enable Camera Access

To scan a QR code using the default camera app or any other QR code scanning app, you need to grant access to your device’s camera.

• Navigate to Settings > Security.
• Scroll down and toggle on Camera.

Step 2: Open the Camera App

You can use either the default camera app or a dedicated QR code scanner like Google Lens.

• For the default camera app:
  • Tap the Camera icon to open the app.
• For Google Lens:
  • Find and tap the Google Lens icon in your app drawer.
  • Grant permission for access to your camera when prompted.

Step 3: Point the Camera at the QR Code

Carefully position the QR code within the frame, ensuring it’s fully visible. Hold the phone steady and wait a few seconds for the camera to process the image.

Step 4: Tap on the Recognized QR Code (Optional)

If your device recognizes the QR code, you might be prompted to tap on it to access the encoded content. This step is optional, as the app may automatically scan and open the corresponding link or action.

Step 5: Wait for the App to Launch or Process the QR Code

Once the scanning process completes, your device will attempt to open the associated application, show you a message with the encoded information, or perform another action based on the QR code’s content.

Tips and Tricks

• Use the right lighting: Ensure sufficient natural light when trying to scan a QR code.
• Clean the camera lens: Dirt and smudges can obstruct your device’s ability to read QR codes accurately.
• Check for QR code quality: Verify that the QR code is legible, has no errors, and meets necessary standards.
