[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

Yes. «DiyA.Podpis» — this is a qualified electronic signature (KEP), which fully complies with the requirements of the Law of Ukraine «On Electronic Trust Services». It is considered equivalent to a handwritten signature and is accepted by courts, tax authorities and banks without any additional confirmations.

On the monitor screen, the user is shown a dynamic QR code. The user opens the "Diia" app on their phone, scans the code with the built-in scanner, undergoes facial biometric verification (FaceID) and confirms the signature application. The site instantly receives the signed file.

During regular loading, users often send low-quality or cropped photographs, and managers have to manually re-enter the data. Action.Sharing officially verifies the data in structured text format (JSON) along with a digital copy of the document in PDF format, protected by the Ministry of Digital Transformation's electronic seal.

The approval process of the request and the use case scenario usually takes from 5 to 10 working days. We take full technical and procedural preparation of the documents upon ourselves to minimize the review time.

Yes, we are developing a unified multimodal widget. The user can choose themselves: sign via the «DiyA» app using a QR code or download a file of their key (for example, a KEP from PrivatBank, Vchasno or CSK «Ukraine») and enter a password.
