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.
