System Architecture

How TAGBASE is architected to deliver secure, scalable, and app-free product verification.

TAGBASE is built as a modular system that connects physical NFC tags with cloud-based verification, analytics, and (optionally) blockchain infrastructure. It is optimized for low friction on the end-user side and high security and extensibility on the backend.

Core Components

1. NFC Tags

  • Hardware: NTAG 424 DNA chips

  • Security: AES-128 CMAC, unique UID, anti-cloning counter

  • Data: Pre-encoded secure URL with crypto parameters

2. User Interface

  • Device: NFC-enabled mobile phone (iOS/Android)

  • Interface: Default mobile browser (no app)

  • Behavior: Tap-to-open secure URL

3. Verification API (Backend)

  • Built with Elixir + Phoenix for fault tolerance and speed

  • Stateless endpoint that verifies each scan using:

    • Encrypted URL tokens

    • Session tracking and delta analysis

    • Tag state and activation status

  • Connects to internal services: logging, analytics, blockchain, and portals

4. Verification Database

  • Stores:

    • Tag status (active/inactive)

    • Scan history

    • Session deltas

    • Optional ownership metadata

  • Powered by PostgreSQL, with pgvector for advanced tracking and embeddings

5. Web Portal

  • Internal + customer-facing UI

  • Supports:

    • Tag batch management

    • Live verification map

    • Order and analytics dashboards

6. Blockchain Integration (Optional)

  • Chain support: Cardano, Ethereum, Solana

  • Use cases:

    • Minting NFTs or fungible tokens

    • Ownership records

    • Resale tracking


Scalability & Modularity

TAGBASE is designed to support:

  • Thousands of concurrent scans

  • Millions of tags

  • Distributed tag writing via Raspberry Pi + USB writer systems

  • Lightweight deployment on edge devices (in progress)

Each component can be independently scaled, replaced, or extended via API.
