Method 4Use MeSince eSigning System (MSS) for batch eSigning

They can deploy MSS in the internal network that connect to the management information systems to achieve one-click PDF signing automatically. The signed PDF document is Adobe trusted with timestamp signature and support LTV (Long Time Validation). Please refer to the Solution for details.
