Are SignAja digital signatures official and legally valid?

Yes. Official digital signatures produced by SignAja are legally valid under the ITE Law. For documents with high legal risk, certified electronic signatures are available through a PSrE registered with Kominfo.

What is the difference between a regular and a certified electronic signature?

A regular electronic signature is enough for internal documents and simple agreements. Certified electronic signatures are used, for example, for high-value contracts, because the signer's identity is verified by a PSrE and backed by a digital certificate.

How do I check an electronic signature that has already been applied?

Every document carries an audit trail with the time, identity, and verification method. You can check the electronic signature directly from the SignAja dashboard or through the digital certificate embedded in the PDF file.

Can I create an electronic signature directly from my phone?

Yes. The recipient just opens the link sent over WhatsApp and creates an electronic signature by drawing on the phone screen. No app installation needed.

How many people can use this e-signature app at once?

One document can be sent to many signers at once, in an order you can set. This digital signature app also supports bulk sending for hundreds of similar documents.
