Physical × Digital

Proof you can tap.

ValidTap gives a physical object an identity that can't be forged, a memory of every time it's touched, and an owner that travels with it. One tap, any phone, no app.

How it works

A secure NFC chip is embedded in the item. Everything else happens in the tap.

1

Tap it

Hold a phone to the card. No app to download — it just works on any modern iPhone or Android.

2

It proves itself

Every tap generates a fresh, encrypted, one-time code. Genuine items verify instantly; clones and copied links are rejected.

3

Unlock what's inside

The verified owner opens exclusive content — and it travels with the card to whoever owns it next.

Why it's different

Not a QR code and not a sticker — a tamper-proof identity enforced by the chip itself.

✓
Unforgeable. Each tap is freshly encrypted and counted, so a copied card can't reuse an old one.
✓
Owner-bound. Ownership transfers only with a real tap — a captured link is worthless, so resale becomes trustworthy.
✓
Living. Cards can evolve and unlock new content over time, controlled remotely — without ever re-touching the chip.
✓
No app, any phone. A tap opens a normal web page — nothing to install, works out of the box.

Built for anything worth proving

The same technology reaches far past cards — any market where authenticity, provenance, or a physical-to-digital bridge carries value.
