A signature that leaves no room for denial:
Verified identity before every signature.
Before the other party picks up the pen, they go through a full session verifying their real identity: an official government document checked automatically, and a live face match confirming they are the person on that document. The result is a contract with the highest degree of legal standing — one they will find very hard to deny signing later.
Identity verification is an optional service added to a contract when you send it, and it is billed per unit from a credit balance separate from your plan.

Why does Identity verification give your contract the strongest legal standing?
An ordinary signature proves that someone pressed a button — not who pressed it. Identity-verified signing turns that around: every signer has to pass a government identity check with an official document and a live face match before the signing page even opens for them. That is why a contract signed this way reaches the highest degree of proof available, and closes the door on Denial, impersonation and challenges to the validity of a signature.
Standing before the courts
An identity verified with an official document and a live face makes denying the signature all but impossible in any dispute, because the signer proved who they were with objective evidence at the moment of signing.
Protection against impersonation
Nobody can sign in someone else's name — the live face has to match the holder of the official document, and recorded photos and videos are all rejected.
Live face match
A live selfie with liveness detection confirms the person is genuinely present at the moment of verification — not a photo and not a deepfake.
Detecting document forgery
The document's security features, its fields and its expiry date are checked automatically within seconds, so forged or altered documents are rejected before signing is allowed.
A verification report linked to the contract
The verification result, its level and its timing are tied to the contract, the event log and the cryptographic fingerprint, and appear among the final contract’s evidence and on the public verification page.
Works with Arabic and international documents
ID cards, passports, driving licenses and residence permits from more than 180 countries — for Arabic and international documents alike.
From sending to an authenticated identity in 4 steps.
You send the contract as usual, and the system handles the full verification before it allows signing.
Secure verification session
A custom Wthaiq-branded link the signer opens from their phone in a minute — no app, no account.
Choose the official document
They select their country and document type: national ID card, passport, driving license, or residence permit.
Scanning the document and the face
Live capture of the document and a selfie with liveness detection, rejecting photos, screens and deepfakes.
An authenticated identity tied to the contract
The signing page opens, and the verification report is attached to the contract and its event log as permanent evidence.
For every contract that leaves no room for doubt.
High-value contracts
Large deals and financial contracts where any challenge is expensive — they deserve the strongest identity proof available.
Dealings with new parties
When you contract with a party you do not know personally, identity verification makes sure the person who signed really is who they claim to be.
Sensitive documents
Powers of attorney, declarations and financial authorizations — any document where a mistake is expensive needs an authenticated identity before signing.
Proof that cannot be denied
Any contract where you want to shut the door on denial completely and prove each party's identity beyond any doubt.
Everything you need to know about Signing with identity verification.
How is identity verified?
Verification begins with a secure, dedicated session branded by Wthaiq that the signer opens on their phone — no app to install and no new account. They select their country and the type of official document they hold — national ID card, passport, driving license, or residence permit — and photograph the front of the document, and the system automatically checks its security features, its data fields, and its validity. Next it asks for a live selfie with liveness detection to match their face against the document photo, and printed photos, recorded video, and deepfakes are rejected. Once verification succeeds, the signing page opens and the verification report is attached to the contract.
What is the difference between it and an ordinary OTP signature?
An OTP proves the signer controlled a particular email address at the moment of signing — useful and fast, but it does not tie the signature to one specific real person. Identity-confirmed signing adds a far stronger layer: it ties the signature to an official government document and to a live face matching that document. The difference is between "someone who received the code" and "this particular person, with confirmed identity, is the one who signed." That is why we recommend it for contracts that need proof beyond argument.
How does this strengthen the contract's legal standing?
The evidentiary weight of a contract grows with your ability to prove the signer's identity. When we tie the signature to an official document and a live face match, denying the signature becomes nearly impossible, because the signing party proved their identity with objective evidence at the very moment of signing. All of this is recorded in a verification report linked to the contract, to the timestamped event log, and to the document's digital fingerprint (HMAC-SHA256), and any modification after signing immediately breaks the fingerprint match. The result is a complete evidence file you can rely on before any authority.
Which documents and countries are supported, and how is my data protected?
The feature supports official documents from more than 180 countries: national ID cards, passports, driving licenses, and residence permits — Arabic and international documents alike. Verification runs through a specialized, accredited verification provider, the connection is fully encrypted, and the document and face data is used for one purpose only: proving identity for the contract itself. It is never made available to any third party and never used for any commercial purpose. What is kept with the contract is the verification result and its level, not the raw images of your documents.
FAQ before the first check.
You, as the sender, bear the cost (verification credit or instant payment); the signer pays nothing, needs no app and needs no account on the platform.
Each signer has one verification session on the same signing link. If they are asked to redo a specific step, such as an unclear photo, they redo it in the same session at no extra charge. If the verification is declined or the session expires before it is completed, no further attempt is available from the same link, and the contract stays locked for signing until you send it to them again, which uses a new verification unit.
No — the signer opens the session link straight from their mobile browser, photographs their document and their face, and that is it. No app, no account, no installation.
A verification report with the result of the check, its level and its timing, tied to the contract, its event log and the cryptographic fingerprint — it appears among the final contract's evidence and on the public verification page.
Verification runs through an accredited provider over an encrypted connection, and the document and face data are used solely to prove identity — they are not made available to any other party and are not used for any commercial purpose.
ID cards, passports, driving licenses and residence permits from more than 180 countries, Arab and international — with the document's security features, fields and validity all checked automatically before it is accepted.
