I worked at a company that used badge-in data to determine how many people to expect for lunch (which the company provided). Given the terribly ancient tech that system ran on, I'm certain that around 11AM every day the person responsible for producing lunch would import a CSV file into Excel and tally the list, all in plaintext. Granted, that's probably an odd exception to the norm, but your comment reminded me of how badge-in data presented a clever solution to a problem, even if I shudder to think of how that data could have been used for harm.
