A badge that looks like what it is: rare
Verification is the scarce resource of the agentic web — but most proof looks like a gray checkmark. Holo ID gives a verified identity the physical presence it deserves: a security-printed card with guilloché line-work, a holographic foil seal, a signing chip, and a QR code that resolves to the live profile. Rendered in real time, reflecting a studio light rig, at 60 frames per second.
It's not a video of a card. It's the card. Game lobbies, stream overlays, profile pages, docs — anywhere an iframe works, your ID is there, in 3D.
What's on the card
Front
Display name, @handle, role, and the profile's did:web DID —
plus a scannable QR that opens the live username.md profile.
Back
Verified links, signature strip, and a serial barcode derived from the handle. Double-click the card to flip it.
Holographic foil
A custom iridescence shader shifts a thin-film rainbow across the face as the viewing angle changes — concentrated on the HOLO seal, just like the real thing.
Physically based
Metal chip, gloss map, clearcoat, and image-based studio lighting. Built on the open-source PlayCanvas engine. No plugins, no assets to download — the whole card is drawn procedurally in your browser.
Embed it anywhere
One iframe. The card ships with a transparent chrome-free mode for overlays and profile pages.
Drop-in embed:
<iframe src="https://badge.md/holo/card.html?chrome=0" width="640" height="400" style="border:0;border-radius:16px" title="Holo ID"></iframe>
Works in stream overlays (OBS browser source), notion-style docs, and any site that allows iframes.
Every user already has one
Pass any username.md handle and the card hydrates itself from the live profile API — real name, tagline, DID, links, and avatar, straight from the profile. The VERIFIED mark only renders when live data actually loaded; unclaimed handles say so honestly.
| Param | Meaning | Default |
|---|---|---|
handle | username.md handle — the card loads this profile's live data (QR, serial, barcode, links, avatar) | chris |
name / title / did | Explicit overrides — win over live profile data | from the profile |
live | 0 disables the profile fetch (params only) | 1 |
chrome | 0 hides the viewer UI (for embeds) | 1 |
Examples: card.html?handle=shannon (live profile) · card.html?handle=scout&… (unclaimed → the card says so)
Proof you can wear. Now in 3D.
Holo ID is an early-access badge.md surface. Cards mint against verified username.md profiles — claim your handle and your Holo ID follows.
