iOS what camera(s) to choose for only reading a QR-code?

[Klaus major-k]

Hi friends,

in my app I only need the user to scan a qr-code.
No picture or video will be taken!

Which of these cameras do I need to check in the STAB 
for this purpose?
Still camera
Auto-Focus camera
Front-facing camera
Video camera

Thanks in advance!


Best

Klaus
