- Use a reputable scanner app: Make sure to use a trustworthy QR code scanner application. Avoid downloading random or unknown apps for this purpose.

- Keep software updated: Regularly update your operating system, browser, and any other apps on your device to ensure you have the latest security patches.
- Be cautious with unknown sources: Avoid scanning QR codes from untrusted or unknown sources. Stick to codes provided by reputable sources.
