Can an AIR mobile-app interact with native mobile app?

Can I get an AIR mobile-app to interact with a native mobile app?

In other words, if I found a decent QR-Code reader program written for an iOS device, could I get my AIR app to start that app, switch to that app, then take the data read by that app and switch back to my AIR app, importing the data into my AIR app?  Or is that beyond an AIR Mobile App's abilities?

I ask because I just can't seem to get a successful QR-Code reader-app going in AIR...  Been at this for quite awhile now, and no luck...  But I can download tons of native iOS QR-Code reader apps, and they all work fine...  So if I can just get one of those apps to send data to my AIR app, then I can probably make it work...

Thanks,
