Beijing, China — April 20, 2026 — Hanvon today announced expanded SDK support covering Windows, Linux, and macOS, making it easier for developers to integrate signature capture and handwriting restoration into existing business systems.
The updated SDK provides a unified set of interfaces across all three platforms, including lib.dll, OCX, and WebSocket support. Developers working with C++, .NET, and Java can now use the same integration approach regardless of the operating system.
The SDK is provided free of charge and can be embedded into third-party applications without modifying the core business system. Signature data can be synthesized into PDF or OFD documents for archiving and audit.
"Our goal is to make integration as simple as possible. Developers should be able to add signature capture to their systems in days, not months.
The expanded SDK is available immediately for all Hanvon electronic signature terminals, including the ESP370U, ESP500, ESP560, ESP700, ESP1020E, and ESP1331.
Hanvon Technology Co., Ltd. focuses on paperless electronic signature terminals and solutions. Its product line covers 3.7-inch to 13.3-inch signature pads, embedded modules, and pen displays, serving banking, communications, retail, securities, insurance, healthcare, and enterprise office industries.
