Am I right in assuming that we could use this in our apps to do different things other than a promo?

I don't think so - it's only used when you trigger the Redeem Code action and you scan the code via camera ...

I can't catch that before it triggers a "call" to Apple to very the code and do something else? I'm thinking of rerouting to a feature inside my app that's special to users of that code.

Users redeem codes from inside the App Store app on their phone.

You can generate codes to give you app away for free, or to grant a free in-app purchase, but that is all. There's no callbacks from the app store to your app to intercept.

Possibly you could do what you want with QR codes and launch URLs, or by doing camera+OCR stuff yourself inside your app.

It's also likely a copyright violation to use that font file without permission.

Typefaces have never been copyrightable in the US, but digital fonts implementing a typeface have been since the early 90s.

This all sounds like it was done without duplicating the font itself (aside from installing it, which does make a copy in one of the Library/Fonts folders, but afaik that isn't been considered duplication for copyright purposes). And it could be done easily enough without even making that copy (a symlink would likely do it).

RedLaser had an barcode and QR code OCR framework you could license a while ago. Don't know if it still exists.

Can you build your rerouting function as part of an in-app purchase and then use the code to activate it?
