Give the finder one useful next step.
Choose a contact page you are comfortable sharing and supply its URL with your order. The NFC tag opens that destination. The page service controls what it shows and who can see it; the tag does not hide a phone number or send an alert.
Keep the child’s details off the outside.
A finder needs a route to the parent, not a profile of the household. Leave the child’s full name, photo, home address, schedule, and medical details off a public page. Review the page from a phone that is not signed in as its owner.
Give caregivers a separate, tested route.
If a trusted caregiver needs bag routines or handoff details, put them on a different page with access controls you have tested. Do not put caregiver-only instructions on the public finder page. Tap the tag with a compatible phone and confirm the intended destination opens.
