Parents often rely on quick fixes to keep their children safe in crowded places — dressing them in bright colours, setting meeting points, or having them memorise phone numbers. Some use ID bracelets, temporary tattoos, or even AirTags, but these solutions have clear limitations. They depend on a child remembering instructions, a bystander noticing an ID, or technology that fails in high-traffic areas. For real peace of mind, a smarter, more reliable solution is needed.
