The linked article is pretty vague about what kind of data is being stored and tracked. Most-likely the system is a simple gatekeeper and doesn't have the ability to monitor what a child is getting at lunch. Also, the data sent to the government is not defined, it likely has no personally identifiable data, just usage statistics (124 kids got lunch on Wednesday), but I'd like to see the data sent. It could very well be sending private information in plain-text across the internet, by design or incompetence...

Careful, it kicks you down a bottomless pit if you type something in it doesn't like.
