Turn certificate requirements into a signing policy
Before preparing a document, identify why a digital certificate is required: an internal policy, a receiving party’s requirement, or the legal conditions of the transaction. This separates the signing method you need from the evidence you will need when reviewing the contract later.
WQ3 has exactly three signing levels: electronic signature, remote signing and token signing; certificate-based signing is not a fourth level. For formal or high-value contracts, assess remote or token signing and document each party’s requirements before sending, rather than relying on the feature name alone.
Separate account verification from signing requirements
If a transaction requires proof of the account holder’s identity, assess that requirement separately from the required signing method. WQ3’s eKYC is an account-verification add-on, and an eKYC-verified account can be required with any of the three signing levels.
In practice, your team can record two decisions for each signer: the required signing level and whether account verification is mandatory. Keeping those decisions separate makes the policy clearer for signers and reviewers, without treating account verification as an additional signing level or a replacement for a required certificate.
Prepare the evidence for later review
Reviewing a certificate-based signature involves more than checking for a visible signature mark. Keep the final document alongside its completion certificate and audit trail so reviewers can examine the action history from sending through final signature, including who acted and when.
WQ3 also provides a public check page accessible without an account, using the contract’s QR code or reference. Reviewers can inspect signer names, signature levels and timestamps, while the SHA-256 fingerprint comparison reveals changes to the file; this addresses document integrity separately from whether the transaction meets its legal requirements.
Review legal acceptance before sending
Egypt’s E-Signature Law No. 15 of 2004 and its executive regulations give electronic signatures and electronic documents legal validity when their conditions are met. Do not assume that using any digital certificate, by itself, satisfies every condition applicable to a contract or its receiving organisation.
WQ3 is aligned with this framework and supports signing evidence through signer identity checks, individual signing links, tamper-evident final documents and an audit trail. Before sending a consequential document, ask your legal or compliance owner to identify acceptance requirements and the evidence to retain, giving signing and review decisions a clear basis.

Frequently asked questions
Is certificate-based signing a fourth WQ3 level?+
No. The three levels are electronic signature, remote signing and token signing; this page does not introduce another level.
Does eKYC replace a required certificate?+
No. eKYC verifies the account holder; it does not replace the signing level or certificate required for the transaction.
Is the completion certificate the signing certificate?+
No. They serve different purposes: the completion certificate accompanies the completed document and audit trail, rather than being the certificate used to sign.
Does a reviewer need a WQ3 account?+
No. The public check page allows access without an account to review the signing record and compare the file fingerprint.
Does a digital certificate guarantee legal acceptance?+
No. Legal effect depends on applicable legal conditions; any specific acceptance requirements of the receiving organisation should also be reviewed.
