Not all QR codes can be scanned, as they might be damaged, too small, or poorly printed. For a QR code to be scannable, it needs to be clear and intact. Most modern smartphones can scan QR codes directly through the camera app, but the contrast and size of the QR code play a significant role in its scannability. If a QR code doesn’t scan, try to adjust the angle or lighting, or use a QR code scanning app with enhanced decoding capabilities.
