ISO/IEC 24779-9:2015规定了与血管图像识别结合使用的符号和图标。 它指定了一系列与生物特征注册、验证和/或识别设备相关联的符号和图标。图标用于在视觉显示屏上显示。符号印在标志和印刷文件上，包括用户文件、分发文件、培训材料、安装/维护手册，以及设备的外壳或按键顶部和按钮上。 这些符号和图标旨在显示生物识别的模式，并建议使用生物识别系统所需的适当准备和行为的必要性。ISO/IEC 24779-9:2015侧重于与数据采集主体的通信。 运营商可以使用ISO/IEC 24779-9:2015，但他们可能需要额外的符号和信息。

ISO/IEC 24779-9:2015 specifies the symbols and icons to be used in conjunction with vascular image recognition. It specifies a family of symbols and icons used in association with devices for biometric enrolment, verification, and/or identification. Icons are for display on visual display screens. Symbols are printed on signs and printed documents including user documents, hand outs, training material, installation/maintenance manuals, and on case or key tops and buttons of devices. The symbols and icons are intended to show the modality of biometrics and to advise the necessity of appropriate preparation and the behaviour required in order to use the biometric systems. T ISO/IEC 24779-9:2015 focuses on communication with the data capture subject. Operators could use ISO/IEC 24779-9:2015 but they might need additional symbols and information.
