Give them a pen. We'll handle the proof.
iSignature is an embeddable SDK that captures more than a signature — photo ID, a live selfie, and the signature itself, bundled into one verifiable audit trail your business can stand behind. On the web, in iOS apps, and in Android apps. No separate KYC tool, no signature-pad hardware.
One email when we launch. Nothing else.
Three steps. No hardware.
From an empty form field to a complete audit trail — signature, ID, and a live selfie — without your users leaving the page or app they're already in.
Embed
Drop the SDK into your site or app with a single snippet. Works with any stack you're already running.
Capture
Your user signs, then photographs a passport or driving licence and takes a live selfie — all in the same flow, no redirect required.
Verify
We timestamp, hash, and bundle it all into one verifiable audit trail you can store, check, or export anytime.
<script src="cdn.isignature.io/v1.js" data-key="pk_live_..."> </script>
A single script tag renders the signature pad inline, in a modal, or embedded in a form.

Security is the product, not a feature.
-
Encrypted in transit and at rest Every capture is encrypted the moment it's taken — signature, ID scan, or selfie.
-
Tamper-evident by design Any edit to an audit trail after signing is detectable.
-
Government ID handled with the same rigor Passport and driving licence scans, plus the matching selfie, are captured and stored under the same protections as the signature itself.
-
You control retention Export or delete audit trail records — signature, ID, and selfie — on your own schedule, not ours.
One subscription. Every platform.
iSignature ships as a straightforward monthly subscription — no per-signature fees, no separate ID-verification tool to buy, no separate charge per platform. Final tiers and pricing are announced at launch.
