There's a quote from an administrator saying the previous attendance system wasn't working well. No details. No way to figure out what problem this is supposed to solve, and how.
It's easy enough to take attendance in homeroom. Teacher signs in to his computer and the homeroom list is there. Kids are present by default so Teach doesn't spend more than a moment checking off the kids who aren't there, and then submits the form. Done.
Office staff run a report five minutes after the start of homeroom. If any teacher hasn't taken attendance then she gets a reminder. Office staff have been getting calls from parents for half an hour before homeroom started, so as soon as they have the report they're ready to see which kids were marked absent by the teachers (must call parents to verify) vs marked absent by office staff (parent has already contacted the school).
No fingerprints. Human-based facial recognition technology is probably quite a bit more accurate, doesn't spread germs in most cases and rarely raises questions of citizen rights.
Apart from the total lack of detail in the news story, the reporter managed to spell "buses" right and then blew on "isles".
