Currently, all business operations can use 1Office digital signatures: labor contracts, commercial contracts, internal business documents (advance payment requests, reward decisions, etc.)

For commercial contracts, the 1Office user signs with an HSM digital signature while the business partner can use a USB Token to sign. Therefore, transactions can still proceed normally.

After creating a task from the digital signing workflow template, users can perform the signing action directly on the workflow task. Users can upload a file or sign an existing file.
