kSign · Electronic signature
Electronic signature, legally compliant
kSign gets PDF documents signed electronically, legally valid and friction-free: the signer receives a link, opens the document and signs from any device. No printing, scanning or mailing.
You upload a PDF, name who signs, kSign does the rest
You upload a PDF and name who must sign: kSign handles delivery, identity verification, signing, the certificate and an event log in which any tampering shows up — with full traceability of every step. Compliant with the eIDAS Regulation (EU 910/2014, Art. 25) and the Italian CAD (Legislative Decree 82/2005, Art. 20).

Getting a document signed shouldn’t take a whole day
Print, scan, courier — or a “graphic signature” pasted onto the PDF, with no evidential value. With kSign the document is signed from the browser and the signature has full legal value.
Without kSign
- Print, sign, scan and mail back: days lost on every document
- A signature pasted onto the PDF proves neither who signed nor when
- No traceability: impossible to prove the document’s integrity
With kSign
- The signer receives a link and signs from the browser in seconds
- A signature with full legal value (eIDAS + CAD) and verified identity
- Hash chain and verifiable log: tampering is detected, the proof remains
How it works, in 3 steps
From creating the request to signing, with no sign-up for the signer.
- Step 1
You upload the PDF
Guided creation: give it a title, upload the document and add the signers’ details.
- Step 2
OTP verification
The signer opens the link and confirms their identity with a 6-digit code by SMS, or with the CIE for the advanced signature.
- Step 3
Sign from any device
Confirm the signature from a computer, tablet or phone. The certificate and history are generated automatically.
Real legal value, not just a graphic signature
Every event generates an SHA-256 hash that includes the previous one: if anyone alters the log, the chain breaks and it shows. Every signature produces a PDF certificate with a QR code, signer details, the document hash and the full chain, which anyone can verify on a public page.
AES with the Italian eID, when you need stronger proof
Beyond the simple signature (SES), kSign can elevate a signature to an Advanced Electronic Signature by verifying the signer’s identity with the Italian Electronic Identity Card (CIE 3.0) and the CieID app. The certificate includes an “Identity verification” section with the regulatory references (Art. 26 eIDAS, DPCM 22/02/2013).
In person and inside your systems
Signing where you need it: at the desk on a tablet, or connected to your systems through webhooks.
Sign “at the desk”
Signing stations on a tablet, PC or kiosk: the customer signs on the spot, with an SMS code or CIE too, on a waiting screen with your brand.
Webhooks and integrations
HMAC-signed webhooks notify your systems of every event (sent, signed, completed, refused, expired); from Files you send a document for signature in one click and the signed copy returns to its folder.
With kSign contracts get signed the same day, with the same legal value as paper — and no more queuing at the printer.
Signing, integrated across the whole ecosystem
Same login and same visual identity as every Kamzan tool. From Files you send a document for signature and the signed copy returns to its folder, Upload Flows adds signing to document collection flows, Kamzan Desktop opens kSign when you drag in a PDF, and pending signatures show up in the other apps.
Everything you need to get documents signed
-
Simple signature with SMS code
The signer gets the link by email, confirms with an SMS code and signs from phone or computer. Legal value under eIDAS, and every step stays on record.
-
Advanced signature with CIE
The signer confirms their identity with the Italian electronic ID card (CIE) and signs with the value of an advanced electronic signature (eIDAS art. 26). Provider details in the certificate and a ready-made FEA manual.
-
Signers, deadlines and reminders
One contract signed by everyone on the same PDF, or a copy for each person, with a deadline, automatic reminders and a list that shows where every signature stands.
-
Document preparation
Drag signature, text, date, checkboxes and statements onto the PDF; the signer’s details fill themselves in and placeholders in the text position the fields for you. Word files too.
-
Document and email templates
The contract you send every week is prepared once: PDF, signers by role and fields already in place. And the email text is written once, with the signer’s details filled in.
-
In-person signing
The client is right in front of you: the document reaches the station, they confirm with an SMS code or Italian eID (CIE), sign and get the copy by email. Stations connected with a link or a QR code.
-
Audit trail, certificate and verification
Every step of the signature recorded in a SHA-256 hash chain, a certificate with QR code, a public verification page, an RFC 3161 timestamp and documents encrypted per company.
-
Integrations and branding
Send for signature from a file in Files, sign inside Flow workflows, drag a PDF onto Kamzan Desktop. HMAC-signed webhooks, your company’s logo and colours, clear credits.
Frequently asked questions about electronic signature
Does electronic signature have legal value?
Yes. kSign complies with the eIDAS Regulation (EU 910/2014, Art. 25) and the Italian CAD (Legislative Decree 82/2005, Art. 20): the signatures collected have full evidential value, with signer identity, event traceability and an audit trail.
Do signers need a Kamzan account?
No. The signer opens a public link and signs from the browser without signing up; identity is verified with a one-time code by SMS or, for the advanced signature, with the CIE.
Can I sign from a phone?
Yes. kSign works from the browser on computers and mobile devices — and in person from a tablet station in kiosk mode.
What’s the difference between SES and AES?
The simple signature (SES) verifies identity with a one-time code by SMS; the advanced signature (AES) verifies it with the Electronic Identity Card (CIE), for stronger evidential value. Choose the level request by request.
What makes a signature non-repudiable?
Every event generates an SHA-256 hash chained to the previous one: any tampering with the log is detectable, and the certificate’s QR code links to a public verification page.
Where are signed documents stored?
Encrypted at rest (AES-256-GCM) in your Kamzan space, on servers in Europe, always available to consult and download together with the signing certificate.
