Cryptographically-Signed NFC Digital Identity Platform
NFC-enabled digital identity with ECDSA P-256 signing, multi-tenant RBAC, and JWT edge verification.
Identity Capsule OS (v1.1.1) bridges physical NFC sharing and cryptographic integrity. ECDSA P-256 signed identity payloads, multi-tenant RBAC with 4 roles, and JWT edge verification with Upstash sliding-window rate limiting protect every endpoint. Three NFC payload modes: URI (~50B minimal), vCard MIME (~500B contact card), and Identity Packet (~2.5KB full cryptographic proof). Defense-in-Depth stack: Zod input validation, Prisma parameterization, edge rate-limiting, and JWT boundary enforcement. Built on Next.js + TypeScript + Prisma + PostgreSQL + Tailwind. Dual-licensed Apache 2.0 / MIT.
