I worked at RedBox in 2010. C# with embedded Lua for the screens. The intent was to build a flexible architecture for CoinStar to use on many kiosk businesses.
The PII is likely log files that should have been erased nightly, but I don’t remember.
I know the guy that designed the architecture. He’s a friend that I’ve argued with about over-engineering things. He never cared if people understood his work, which is a common theme with old school engineering.
