Physical documents are gradually being replaced by digital versions—and the same goes for signatures. Online document signatures are no longer just a convenience; they’ve become a necessity.
The process of signing documents online not only speeds up workflows and reduces paper usage, but is also aligned with regulations set by Komdigi.
However, not all online signatures are legally valid or compliant with Komdigi standards. Since everything is done digitally without face-to-face interaction, there are important factors to consider to ensure that digitally signed documents remain valid and secure.
5 Ways to Sign Documents Online
As the demand for digital signatures increases, various methods have emerged. However, not all offer the same level of security or legal validity. Here are the most common approaches:
1. Image/Scanned Signature
This is the simplest form of online signature—using an image, photo, or scanned version of a handwritten signature. Many people use this method because it’s easy: sign on paper, then insert the image into a digital document.
While quick and convenient, this method is highly vulnerable to forgery, as there is no way to verify the signer’s identity.
2. Signing via PDF Tools
Many PDF tools now allow users to draw or insert signatures directly within the document without printing.
Although practical and easy to use, this type of signature does not include identity authentication or formal legal proof. It is generally suitable only for internal or non-critical documents.
3. Electronic Signatures: Non-Certified vs Certified
Electronic signatures (e-signatures) are digital signatures issued by authorized providers known as PSrE (Electronic Certification Authorities).
In Indonesia, Komdigi classifies e-signatures into two main categories: non-certified and certified (digital signatures).
Non-Certified Electronic Signatures
These are easy to use and efficient for lightweight documents. However, they do not involve identity verification (such as ID or biometric checks), meaning the signer’s identity cannot be clearly validated. Typically, only the PSrE provider’s name is visible.
Because of this limitation, non-certified signatures are not recommended for legal or high-risk documents.
Certified Electronic Signatures (Digital Signatures)
Certified electronic signatures—commonly referred to as digital signatures—are the most secure and legally valid form of online signature.
To create one, users must upload their ID (KTP) and complete biometric verification. This ensures that every signature is tied to a verified identity.
Each digitally signed document includes details such as who signed it and when, making it highly reliable for legal purposes.
4. Biometric Signature Verification (SelfieSign)
SelfieSign is a VIDA solution that combines digital signatures with facial biometric verification. Documents can only be signed after the system confirms the signer’s identity through face recognition.
This method is commonly used for quick approval processes, such as in online lending or insurance services.
5. Power of Attorney Signature (POA Sign)
POA Sign (Power of Attorney Sign) is a method where the signer acts on behalf of another party under legal authorization.
VIDA provides this feature for companies that need to sign documents on behalf of directors, CEOs, or legal entities.
This method is ideal for organizations requiring authorized representation, while still ensuring legal validity through electronic certification.
Choosing the Right Online Signature Method
The method you choose should depend on the sensitivity of the document and legal requirements.
- For important or high-value documents, use signatures with verified identity—such as certified digital signatures.
- For companies handling large volumes of users or clients, solutions like SelfieSign (self-verification) or POA Sign (authorized signing) are highly recommended.
VIDA offers a complete range of signature solutions—from basic e-signatures to certified digital signatures, as well as advanced options like SelfieSign and POA Sign—tailored to different needs and risk levels.
