Kind of. Google Now has QR code reading built in, if you have a QR code on the screen (e.g through a camera app) you can have google now scan the screen by holding the home button. I don't remember having to enable it, but if it isn't enabled for android users you can go into Google Now settings and enable "Screen Search".
