For systems like menus, when someone is being banned from a club for example a security officer or bouncer would be able to simply with a website on a smart phone photograph someone Identification like drivers licence and upload it, where I will run it through a debain package called 'gocr' and run OCR on it with correction systems.
ie. https://packages.debian.org/search?keywords=gocr
Passes is the same thing but for checking no one has any identification bannings or to display their blacklistings.
