Steps to create a QR code
- Enter the URL or text and remove any tracking parameters that you know are unnecessary.
- Set the error correction level, margins, and size to suit your needs.
- Check the generated image with another reading function.
- When printing, try printing at actual size to ensure sufficient margins and contrast.
Steps to read from images
- Select an image that clearly shows the QR code.
- Review the decoded content as text. If it is a link, verify the domain and path before opening it.
- Do not open shortened URLs or suspicious domains immediately, and check with the sender.
- For contact details or Wi-Fi settings, review every field before adding the information to your device.
