Cite religious beliefs and not wanting your kid forced to carry the Mark of the Beast. Rattle off some Bible verses from Revelations, complain about persecution of Christians, and you’ll be set.
Or, you know, give actual reality-based reasons and hope for sensible school administrators. At the very least, I would expect them to share a privacy policy explaining what this third-party has access to and what they can do with the data.
Personally, a single “bathroom pass” NFC card that a teacher hands out to any student in their class that needs a bathroom visit wouldn’t cause me much security consternation; that any student could be carrying the pass at any given time is enough anonymztion for my concerns. I’d be more concerned about germs; a group pass is going to get nasty.




This means you need the policy from the school itself so you know what’s actually been agreed to that is applicable to your kid’s data.
Meaning they can sell your data to any who will pay for it.
Meaning they can pull a 23andMe; if they go bankrupt or whatever, they can sell your data and the buyers can do whatever they want with it.
I’d be defaulting to not allowing my kid’s name to be entered into the program, with a steep uphill challenge to convince me with a very robust contract-specific privacy plan. A single, generic pass than any kid might be using at any given time, I’m still fine with that but no individual-assigned tags that get associated with my kid.
