That's kind of my thinking. They probably started from an old paper system, then coded more or less the same thing, poorly - with no one who knew better being involved. All too common. Even if they realize it's a bit lame there's no business incentive for them to spend money to fix it.This violates one of my rules of bureaucratic behavior -- never attribute a decision to intelligence when it can be explained by ignorance. The most likely explanation was that someone wrote the code years ago and assumed people would always write their name and birthday the same way and it would be easy to search (in case anyone actually wanted to search). It just never occurred to anyone at the time to set it up with a single number because they were focused on name and birthdate which I'm sure was a hold over from when they kept records by hand, in alphabetical order.
