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.
