How does a QR code work?

A QR code (Quick Response Code) is a two-dimensional barcode that stores information and can be read using a smartphone camera or QR code scanner.

The code consists of black and white squares arranged in a specific pattern. When scanned, the camera recognizes this pattern and decodes the stored data, e.g., a website URL, a phone number, or Wi-Fi access data.

The structure of a QR code:

• Search pattern: Three large squares at the corners help the scanner align the code correctly.
• Data area: Contains the actual information, e.g., the address, the phone number, or the Wi-Fi access data. B. a URL or text.
• Error correction: Ensures that the code remains readable even with minor damage.

How to scan a QR code:

1. Open the camera app or a QR code scanner app on your smartphone.
2. Point the camera at the QR code.
3. The app automatically recognizes the code and displays the stored information.

QR codes are simple, fast, and versatile – perfect for websites, digital business cards, or Wi-Fi access!
