QR codes are essentially two-dimensional barcodes that store data in the form of square modules. When you scan a QR code from an image using a smartphone app, here’s what happens:
- The app detects the QR code pattern within the image.
- It decodes the QR code using algorithms and error correction mechanisms to retrieve the underlying data.
- If successful, it displays the decoded content on your screen.
Conclusion
Scanning QR codes from photos is a convenient way to access information quickly, especially when the original QR code is not available. By following these steps, you can successfully scan QR codes from images and unlock their associated content.
