# Overview of TAGBASE

**TAGBASE** is a platform that enables secure, app-free authentication of physical products using cryptographically protected NFC tags. It bridges the physical and digital worlds through real-time verification flows, blockchain integration, and tamper-proof hardware — all accessible via a mobile browser.

TAGBASE is designed for easy integration, high scalability, and long-term trust — giving developers everything they need to build secure, verifiable, and transparent systems around physical goods.
