I worked on an AR application working in combination with a published book. There are pages of the book which are augmented with an iOS app using Vuforia. However, the binary got rejected by Apple with the following feedback:

"1.0 Binary Rejected Nov 20, 2017

Guideline 3.1.4 - Business - Payments - Content Codes Your app enables additional features or functionality when used with augmented"

This is the full 3.1.4 guideline:

"3.1.4 Content Codes: Apps may not use their own mechanisms to unlock content or functionality, such as license keys, augmented reality markers, QR codes, etc. In limited circumstances, such as when features are dependent upon specific hardware to function, the app may unlock that functionality without using in-app purchase (e.g. an astronomy app that adds features when synced with a telescope). App features that work in combination with an approved physical product (such as a toy) on an optional basis may unlock functionality without using in-app purchase, provided that an in-app purchase option is available as well. You may not, however, require users to purchase unrelated products or engage in advertising or marketing activities to unlock app functionality."

Has anyone run into this issue before and found a simple workaround?

Thank you
