Apple's iPhones already have built-in 'QR Code Reader' in the Camera app. So there's no need to download or install a separate QR Code Scanner.

In order to read QR codes on Android phones or tablets, you will need an app.

Norton Snap keeps you a step ahead of potential threats and takes the gamble out of using QR codes. It’s the first QR code scanner that protects you, your identity, and your stuff from online threats by checking the safety of websites linked to QR codes before they load on your mobile device.
