4 of 5Next: The same mechanism, any platform Four steps, one screen at a time; every screen is the real product unless marked otherwise.
1

They click your study link

In Alchemer’s invite, your panel, or wherever you recruit. The link opens the check, not your study.
The handoff screen
2

They do the scan

A few seconds in the camera with live prompts. No photo is shared with you or with Alchemer, only a yes or no.
The face scan

The fork: pass or fail

The scan ends one of two ways, and both are instant.

Straight into your study
Screened out. Nothing to pay.

They pass

The success screen

Live and unique. They are sent straight on to your Alchemer login page with their one-time password already filled in, then your questions. (Real product, demo partner brand.)

Alchemer login page pre-filled

The pass lane continues here: your Alchemer login page, password already in the box. With auto-submit on, they skip this page entirely. (Illustration; the real page inherits your study’s theme.)

They fail

Denied screen

A duplicate face, a replay, or a bot. No password, no study, no complete, nothing to pay. They are routed to your panel’s screen-out, and a new device or browser changes nothing, because the check recognizes the face. (Real product.)

The fail lane ends here, by design. There is no page after this one.

When they come back

Same study: a dead end

Their face already earned its one password, and it is spent. One person, one response, permanently.

Your next study: welcome back

Recognized, less friction, and a fresh one-time password for the new study. You are never charged twice for the same human.
