Traditional e-signing
- Identity is an email address
- Anyone with inbox access can sign
- Hard to prove who signed in a dispute
- Audit trail shows clicks, not people
Verified identity signing
Know exactly who signed. Every time.
IDfier Sign ties every signature to a government-issued ID and a biometric check, then seals the document with a certificate anyone can verify.
- Verified signers only
- Tamper-evident seal

The problem
E-signatures were never designed to verify people
Most signing tools only ask for an email address. Anyone with access to that inbox can type a name and click sign, and you have no way of knowing.
IDfier verified signing
- Identity is a verified government ID or BankID
- Biometric liveness check before signing
- Certificate anyone can verify, no login needed
- Audit trail tied to verified people
How it works
How a verified signature is made
From upload to sealed document. Every signer is verified before they can touch your document.

The certificate
Every document ends with proof
A QR code to the public verify page
Scan it, enter the document ID or upload the signed file to confirm the document is genuine. No login needed.
Every signer, verified
Each signature lists the person who signed and how they proved their identity: passport with NFC chip, ID card or BankID.
A cryptographic seal
The certificate is signed with HMAC-SHA256 and the signed file's fingerprint is stored. Change one character and the check fails.
Proof that holds up
Every action on the record. Every signature verifiable.
The audit trail records who did what and when, tied to verified identities. Anyone can check a signed document later, from a judge to an auditor to the other party.

FAQ
Frequently asked questions
What ID types are accepted?
Government-issued passports, national ID cards and NFC-chip driving licences, verified in the IDfier app. Swedish signers can also use BankID.
Is a verified signature legally binding?
Electronic signatures are legally recognised across the EU under eIDAS. IDfier Sign adds what standard e-signatures lack: proof of who signed, through a government ID check, biometric liveness and a sealed audit trail.
What if my signer doesn't have the IDfier app?
They receive an invitation with a link. The IDfier app is free, and verifying an identity takes a couple of minutes. Swedish signers can use BankID instead.
Can I prove a signature is genuine afterwards?
Yes. Every completed document has a certificate. Anyone can enter its document ID or upload the signed file on the public verify page to confirm each signer's identity and the time of signing.
How are my documents protected?
Every document is encrypted with AES-256-GCM before it is stored, and encryption keys are never stored alongside the files.
Can I change or cancel my plan?
Yes. There are no contracts or setup fees. Change or cancel your plan from the Subscriptions page in your workspace.
How is this different from DocuSign or similar tools?
Those tools verify an email address. IDfier Sign verifies a person. For low-stakes forms any e-signature tool works; for hiring contracts, investor documents and cross-border agreements, identity matters.
Stop signing blind. Start signing verified.
