About SentinelTag
A safeguarding and emergency information platform built for vulnerable children and adults.
Our mission
When a vulnerable person is in distress — separated, unconscious, or unable to communicate — the people trying to help them need information fast. SentinelTag puts that information one tap away, securely stored on an NFC tag the individual wears or carries.
We built SentinelTag because paper-based emergency cards get lost, databases take time to query, and phone calls go unanswered. A responder should never be left guessing about a child's name, their emergency contacts, their medical needs, or how to communicate with them.
Every feature — from biometric login to per-user access control — was designed around the real-world needs of schools, care teams, first responders and families who are responsible for keeping vulnerable people safe.
What we stand for
Privacy & security
Sensitive personal data is encrypted at rest. Access is restricted to verified professionals. Every scan is logged.
Speed when it matters
In an emergency, seconds count. SentinelTag is designed to surface critical information instantly — no logins, no searching.
Accountability
Full audit trail of every access event — who viewed the profile, when, and from which organisation. Essential for safeguarding compliance.
Accessible by design
Works on any NFC-enabled Android phone. No specialist hardware, no expensive rollout. A wristband and a phone is all you need.
