Versions:
NHI ServiSign 1.0.23.1227 is a single-purpose security component published by 全景軟體 Changing Information Technology Inc. that enables Windows workstations to recognize and use the National Health Insurance smart-card certificates required by Taiwan’s NHI VPN. Once installed, the package registers the appropriate CSP and PKCS#11 modules so that Internet Explorer, Edge, Chrome, or any government-designated healthcare application can communicate with the card reader, perform mutual TLS authentication, and sign XML transactions on the NHIIS (National Health Insurance Information System) portal. Typical use cases include clinics uploading monthly claim files, hospitals downloading patient Medi-Cloud records, pharmacies reporting controlled-drug prescriptions, and medical-device vendors submitting reimbursement forms; all scenarios depend on the same underlying certificate validation flow that NHI ServiSign facilitates. Because the component is officially mandated by the National Health Insurance Administration, every healthcare institution that exchanges data with the central database must keep this middleware present and up-to-date, usually via the quarterly HI-IS software bundle. The release history shows only one public build—version 1.0.23.1227—indicating that the publisher treats it as a tightly controlled, evergreen module rather than a frequently iterated consumer product. Functionally it belongs to the Security/PKI Middleware category, sitting between the operating system’s cryptographic subsystem and the Java or ActiveX applets that the NHI web applications still employ. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
