How to scan a QR code safely using your smartphone


We recently received this email from a CyberGuy reader asking an important question about QR codes:

Can you recommend a QR code reader that doesn’t require setting up an account? In the App Store, they all have ads and In-App Purchases. Many want you to let them access a lot of non-German information to use it. I’ve had an app for years that didn’t need to bare anyone’s soul and didn’t need access to someone’s phone activities. Suddenly one day I went to use it and things changed. Can you recommend a non-invasive QR code reader app that doesn’t require a lot of hoop jumping and maintains privacy and security?
