NFC product identity for independent brands

Every unit carries its saga.

Put a cryptographic tag on every item you ship. Buyers tap it with their phone to prove it's real, claim ownership, and register the warranty. No app to install — and nothing a counterfeiter can photocopy.

Signature invalid

This tag didn't produce a valid one-time code. It's a copy — a reused code, a photographed QR, or a cloned URL. A genuine SAGAS tag generates a fresh cryptographic code on every tap.

The operation

Three ops. Zero new workflow.

OP 01

Issue

When an order ships, SAGAS issues a serialized identity for that exact unit — edition number, colorway, run. It hooks your Shopify fulfillment flow, so your pick-and-pack doesn't change.
OP 02

Tag

A cryptographic chip rides on the product — woven label, hang tag, or caseback dot. Every tap generates a fresh one-time code. Photocopy the QR, peel the sticker, clone the URL: none of it verifies.
OP 03

Tap

Buyers tap with any phone — no app. They see authentic, edition, and scan history. Claiming registers the warranty and gives you a direct line to the actual owner, including the second owner after resale.

What it buys you

Box and papers, for everything you make.

Resale that holds value

Watch collectors pay more for "full set, papers intact." Your buyers should too. A verified item resells higher — and every resale runs through your brand, not a legit-check thread.

The end of legit-check duty

Your mods burn hours calling fakes in Discord. One tap settles it: verified or not, with the scan history to back it up.

Own the after-sale

Registered owners are a channel you keep: warranty, early access, transfer on resale. The relationship survives the marketplace it was resold on.

Hardware spec

The chip does the arguing.

SAGAS uses NXP's NTAG 424 DNA — the industry-standard secure-NFC chip — at drop-brand pricing. Each tap produces a single-use cryptographic code the chip signs itself. Copies don't compute.

Chip: NXP NTAG 424 DNA
Auth: AES-128 · one-time tap codes
Reads: iPhone & Android · no app
Form: Woven label · hang tag · epoxy dot
Tamper: Tamper-evident variant available
Unit cost: Quoted per run size

From the founder

"I'm Khoa — a full-stack engineer building SAGAS after watching independent brands fight fakes with hologram stickers and Discord threads. I'm recruiting ten design partners this fall. You get the pilot kit and a real say in the roadmap; I get the truth about what's worth building. Email me — I reply personally."
