The default camera app on my Android 10 device doesn't support QR codes, and have to use a third-party app. I have so far narrowed it down to 3 choices.
- Avira - Avira QR Scanner | Secure & Finds Deals
- Play Store - Free QR Scanner by Avira - Apps on Google Play
- Kaspersky - https://www.kaspersky.com/qr-scanner
- Trend Micro - Scan QR Codes Safely with the Trend Micro QR Scanner -
- ease of use
- internet protection against rogue QR code links
- privacy policies when you use the QR app
