The 4 itsme® services for businesses

1. Identification (itsme® Identify)

Enables fast, efficient customer onboarding with instant identity verification. Companies can verify the identity of their customers in a matter of seconds by connecting to official Belgian and European registers. Ideal for opening bank accounts, taking out insurance policies, or any procedure requiring certain identification (KYC – Know Your Customer).

2. Authentication (itsme® Login)

Provides simplified, secure access to online services without the need for complex passwords. Users can connect to their business applications, customer portals or banking services with integrated two-factor authentication. This solution replaces the need for physical tokens and SMS confirmations.

3. Confirmation (itsme® Confirm)

Provides clear approval processes for sensitive transactions. Companies can request explicit confirmation before executing payments, large bank transfers, or contract modifications. This adds an extra layer of security for high-risk operations.

4. Signature (itsme® Sign)

offers a reliable, legally binding and practical method of signing documents online, with the maximum legal value of a Qualified Electronic Signature (QES) in compliance with the eIDAS regulation. This is the service we’re going to describe in detail in this article.

🔐 Maximum safety

itsme® uses a multi-layered security infrastructure with strong authentication, end-to-end encryption and compliance with international standards (ISO 27001, eIDAS). Every transaction is protected by your personal PIN code and your mobile device.

How does a signature work with itsme®? Step-by-step guide

The itsme® signature process has been designed to combine maximum security with ease of use. Here is the complete procedure for a qualified electronic signature with itsme® :

Step 1: Receipt of invitation to sign

You receive an email inviting you to sign important documents. This email contains a secure, personalized link to initiate the signature procedure. The email usually specifies :

  • Name of organization requesting signature
  • Type of document to be signed (contract, agreement, form, etc.)
  • Possible deadline for signing
  • A single, secure link to the signature platform

Step 2: Document access

Clicking on the link in the e-mail takes you to a secure web page displaying the documents to be signed. This page allows you to :

  • View all documents in your browser
  • Read all terms and conditions carefully
  • Download documents for offline consultation if required

Step 3: Mandatory reading and acceptance of conditions

Before you can click on the ‘Sign’ button, you must :

  1. Scroll to the very last page to make sure you’ve viewed all the content
  2. Check the required box: “I certify that I have read all the documents and agree to the Terms of Use”.

This step ensures that you have read the entire document before committing yourself legally.

Step 4: Send the signature request to itsme®.

After clicking on ‘Continue’, you must :

  1. Enter your cell phone number (the one associated with your itsme® account)
  2. Click on ‘Continue’ to send a signature request to your itsme® mobile application.

At this point, a notification is instantly sent to your smartphone.

⏱️ 3-minute delay

Please note: After opening the itsme® mobile application, you have just three minutes to complete all the steps required for signing. This security delay prevents fraudulent signature attempts. If the time limit expires, you will have to restart the process from the beginning.

Step 5: Opening the itsme® application

Open theitsme® mobile application on your smartphone. You will immediately see a pending signature request with :

  • Name of issuing organization
  • The type of document to be signed
  • Action required (qualified electronic signature)

Step 6: Confirmation and verification of security icons

To guarantee transaction security and avoid man-in-the-middle attacks:

  1. Take a close look at the action displayed on the itsme® mobile application
  2. Select ‘Confirm’ to start the signing process
  3. A set of colored icons appears simultaneously:
    • In your web browser (on computer or tablet)
    • In your itsme® mobile application
  4. Check that the icons displayed in the itsme® mobile application correspond exactly to those visible in your browser.
  5. If the icons match, select the orange icon in your browser on your itsme® application.

🔒 Enhanced security through icon verification

The icon verification system guarantees that you are actually signing the document in front of you, and that no malicious intermediaries have intercepted the request. If the icons don’t match, contact the issuing organization immediately.

Step 7: Finalize with your PIN code

To finalize the qualified electronic signature :

  1. Enter your 5-digit itsme® code in the mobile application
  2. Confirm to create the cryptographic signature

This personal PIN ensures that only you can create signatures with your itsme® digital identity.

Step 8: Signature confirmation

Once these steps have been successfully completed :

  • Your browser automatically returns to the document page
  • A confirmation message appears, indicating that the signature is complete.
  • The document is now legally binding.

Step 9: Receipt of signed documents

Once all required parties have signed the document (if multi-party signature) :

  • You will receive an automatic confirmation email
  • This email contains a secure download link to the duly signed documents.
  • Documents include qualified electronic signatures of all parties with certified time stamps
  • You can archive these documents, which have the same legal value as a hand-signed document

Which documents require a qualified electronic signature?

Under the eIDAS regulation, electronic signatures are legally valid for the vast majority of commercial and civil documents. However, Belgian and European legislation specifically requires the use of a Qualified Electronic Signature (QES ) for certain types of document where maximum legal security is essential.

Documents subject to QES in Belgium

Type of documentLegal basisApplication context
Consumer credit contractsArticle VII.78 of the Code of Economic LawPersonal loans, consumer credit, car financing
Employment contractsArticle 3bis of the Employment Contracts ActHiring of employees, amendments, contractual modifications
Authentic instrumentsArticle 8.15 of the Civil CodeNotarial documents, real estate deeds, wills
Official formsTax and administrative regulationsTax returns, applications to public authorities
Company bylawsCode of Companies and AssociationsFormation and modification of SRL, SC, SA, European companies, cooperatives
Electronic government servicesDigital government legislationConnection to My eBox, MyMinFin, Tax-on-web
Merger minutesArticle 12:50 of the Companies and Associations CodeApproval meetings, mergers and acquisitions
Insolvency documentsBook XX of the Code of Economic LawBankruptcy proceedings, compositions, judicial reorganizations

Why do these documents require an ESQ?

These document categories share several common characteristics that justify the requirement for a qualified electronic signature:

  • Significant financial stakes: Significant financial commitments (loans, salaries, real estate transactions)
  • Protecting weaker parties: stronger consumer and employee protection
  • Maximum legal certainty: Need for irrefutable proof in the event of litigation
  • Strict regulatory compliance: Supervision by public authorities (central banks, labor inspectorate, notary’s office)
  • Long-term archiving: mandatory retention for many years (10, 30 or more)
  • Undeniable probative value: Non-repudiation guaranteed by QES

⚠️ Penalties for non-compliance

The use of a simple electronic signature or an advanced signature (instead of a QES) for the documents listed above may result in: nullity of the contract or deed, administrative sanctions, fines for the organization, and non-recognition of the document by the competent authorities.

Documents for which QES is recommended (but not mandatory)

Although not formally required by law, it is strongly recommended to use a qualified electronic signature for :

  • High-value commercial contracts (>€50,000)
  • Sensitive confidentiality agreements (NDA)
  • Strategic partnership agreements
  • Sales of shares
  • Commercial leases
  • Representative mandates
  • International documents requiring cross-border recognition

In these situations, QES offers maximum legal certainty and virtually eliminates any risk of subsequent challenge.

Are itsme® signatures legally binding?

Legal value guaranteed by eIDAS

Absolutely! itsme® signatures are fully legally binding and enjoy maximum protection under European law. Here’s why:

1. Full compliance with eIDAS regulation

itsme® Sign complies with the eIDAS regulation (EU Regulation No. 910/2014), which is directly applicable in all EU member states. This guarantees a legal value equivalent to that of a traditional handwritten signature.

2. Qualified Trusted Service Provider (QTSP)

itsme® works with Qualified Trusted Service Providers supervised by the Belgian and European national authorities. These providers are regularly audited to ensure compliance with the strictest technical and legal standards.

3. Guaranteed non-repudiation

  • The signatory cannot deny having signed the document
  • In the event of a dispute, it is up to the party contesting the signature to prove that it is invalid (reversal of the burden of proof).
  • Cryptographic mechanisms guarantee signature authenticity and integrity
  • Any change to the document after signing is immediately detectable

4. Mandatory cross-border recognition

itsme® signatures are automatically recognized in all 27 EU member states. A document signed in Belgium with itsme® is legally valid in France, Germany, Italy and all other European countries without any additional formalities.

5. Legal equivalence with handwritten signature

According to article 25.2 of the eIDAS regulation: “A qualified electronic signature has a legal effect equivalent to that of a handwritten signature.”

In practical terms, this means that a contract signed with itsme® has exactly the same legal force as a contract signed by hand before a notary.

⚖️ European case law

Belgian and European courts systematically recognize the validity of eIDAS-compliant qualified electronic signatures. Several court rulings have confirmed that QES signatures have a probative value equal to, or even superior to, a handwritten signature, due to the technical guarantees they offer.
