Parta Identity Tag

About Parta Identity Tag

Parta Identity Tag turns NFC badges into device-bound cryptographic identities for physical access control, without a central credential database.

HOW IT WORKS
Each badge (NTAG424 DNA) holds a private key protected through split-knowledge encryption. When a badge is presented to a reader, the system issues a cryptographic challenge and verifies the signature using Ed25519. No password, PIN, or shared secret ever crosses the wire.

WHAT YOU CAN DO
- Provision and manage NFC badges for staff, contractors, or visitors
- Organize badges into groups with their own access policies
- Revoke a badge instantly if it is lost or no longer needed
- Monitor access activity across your locations and nodes

WHY IT MATTERS
Traditional access systems rely on databases of credentials that, if breached, expose every badge at once. With Identity Tag, each badge carries its own cryptographic identity. A centralised breach surface is eliminated by design: there is no single store of secrets for an attacker to target.

PART OF THE IDENTITY LAYER ECOSYSTEM
Identity Tag works alongside Identity IoT and the broader Identity Layer platform, a stateless verification infrastructure built around device-bound Ed25519 keys.

This app requires a Parta Identity account provisioned by your organization. Account management and provisioning are handled through the Parta web platform (parta.app), not inside this app.
