Authentag™ security doesn't rest on a database lookup. It's built on chip-level hardware encryption, cryptographic proof, and a distributed edge network. From the physical layer to the protocol layer, every link is engineered so a verification result can't be forged and data can't be tampered with.
Three carriers share one infrastructure for traceability, tracking and DPP compliance. What differs is the depth of protection: a QR code delivers digital identity and an event record, NTAG 213 adds dynamic clone resistance, and NFC DNA delivers cryptographically uncloneable verification.
Each product's QR binds a unique product code (UID) and a dedicated URL pointing to its own landing page. This satisfies DPP requirements while generating a unique scan event in the system — timestamp and country-level geography — combined with geo-jump detection and replay alerts, for a basic but complete product identity and monitoring layer.
The chip's built-in UID + counter mirroring generates a dynamic URL on every NFC tap; the old link expires automatically, exposing most static-copy and forwarding-style clones. It likewise records scan time, country-level geography and UID association, raising geo-jump and replay alerts.
Built on NXP NTAG DNA chips. Each chip is written with a unique AES-128 key and then permanently locked. Every read produces an encrypted message packet that the server verifies cryptographically. The result is a mathematical proof, not a simple database match — and it distinguishes far more clone and attack patterns.
The system is deployed in the U.S., with verification logic running on 250+ global edge nodes and China acceleration for factory access — keeping the factory, verification and regulatory sides fast and stable.
