Defining QR Codes

Quick Response (QR) codes are two-dimensional barcodes that contain information such as text, URLs, phone numbers, email addresses, and more. They were invented in 1994 by Masahiro Hara of Denso Wave, a Japanese automotive parts manufacturer, to track car parts during manufacturing.

A QR code is composed of several modules (squares) arranged in a square or rectangle pattern. The encoded information is stored in the pattern of these modules, which can be read using a smartphone camera with a QR code scanner app.

Importance and Use Cases

QR codes have become increasingly popular due to their simplicity, versatility, and convenience. They are used in various industries, such as:

• Marketing: To share product information, promotions, or coupons
• Retail: For inventory management, product labeling, and customer engagement
• Healthcare: To track medical records, prescriptions, and patient information
• Education: To provide interactive learning experiences, access course materials, and track student progress

Scanning a QR Code on Your Phone

To scan a QR code using your smartphone:

1. Ensure you have a camera: Make sure your phone has a working camera to capture the QR code.
2. Install a QR code scanner app: You can use a built-in app, such as Google Lens (for Android and iOS), or download a third-party app from the App Store or Google Play Store.
3. Point the camera at the QR code: Hold your phone’s camera over the QR code, ensuring it is centered in the viewfinder.
4. Align the QR code properly: Adjust the camera angle until the entire QR code is visible within the frame.
5. Wait for the app to recognize the code: The scanner will attempt to decode the QR code and display the linked information on your screen.
