How do I setup a QR code scanner using Bitdefender on older iPhones

Charles_I

I have an iPhone 6 and an iPhone 8. Do I need a 3rd party app to use as a QR Code scanner or is this built in to Bitdefender Mobile? If I need a 3rd party app which one do recommend? If it is is built into Bitdefender do I need to download another Bitdefender app, because the Bitdefender Mobile app appears to be only a Dashboard.
