Frequently Asked Questions

Usually not. Apple supports QR scanning in the iPhone Camera app and Code Scanner, while Microsoft supports it in the Windows Camera app. On Android, default-camera support varies by device, so use the QR Scanner Quick Settings control or Google Lens if the camera does not detect the code.

Save or capture the code as an image, then open it with a QR-aware photo or lens feature on your device. Another reliable option is to display the image on a second screen and scan it with the first device's camera.

The code may be too small, blurred, distorted, low contrast, or missing its clear border. Move closer, improve the lighting, clean the lens, keep the camera parallel to the code, and confirm that QR scanning is enabled in the camera settings.

Reading the code only reveals its encoded content; the risk begins when you open an unknown link or follow an unexpected instruction. Review the displayed domain first and avoid entering credentials or payment information when the destination does not match the organization that presented the code.
