This document establishes: —     functional architecture of a Biometric System-on-Card (BSoC); —     definition of Type ID-1 BSoC (ISO/IEC 7810 conformant) and Type ID-T BSoC (see ISO/IEC 18328-2:2021, Annex A) implementation of a BSoC; —     sensor types in a BSoC; —     requirements to a BSoC with respect to: —    discriminative power (i.e. biometric accuracy criteria); —    interfaces; —    power supply options. —     The following aspects are out of scope of this document (see ISO/IEC 24787-1): —     off-card biometric comparison, storage-on-card; —     on-card biometric comparison (sensor-off-card); —     work-sharing implementations; —     detailed specification and configuration of individual components. This document provides a functional architectural description of a BSoC and describes how the interfaces are mapped using existing commands and data structures from other International Standards.
