The computer creates a short-lived receiver QR. The phone opens the handwriting surface directly in its browser.
Show one QR on this computer. Sign naturally on the phone or tablet, undo strokes, choose the ink and return a transparent PNG or scalable SVG over the same verified Phone Bridge used by SCAN.

The computer creates a short-lived receiver QR. The phone opens the handwriting surface directly in its browser.
Pointer input captures real pen pressure when the device exposes it and uses a stable touch fallback when it does not.
Undo removes the last complete stroke. Clear starts clean. Nothing is committed to the computer until you explicitly send it.
Transparent PNG drops cleanly into common documents and slides; SVG keeps a scalable vector representation of the handwriting.
Stroke data stays in the phone browser. Signaling coordinates the devices; the resulting asset returns through WebRTC.
The computer independently verifies SHA-256 before showing the returned signature preview and download.
SIGNPAD captures the mark you draw. It does not claim identity verification, certificate-based signing, qualified signatures, audit trails or jurisdiction-specific electronic-signature compliance.
