My base airport in the US is Atlanta and I have always used the Delta iPhone app which uses a 2D square barcode for a boarding pass.
I had an international flight a few weeks ago and used a paper ticket. For the first time they scanned the paper ticket in the same way as the 2D barcode from the app.
I suspect the "embedded code" is in this 2D barcode and hence why not all airports can "support" this system. They have to have the scanners installed, which most airports don't.
