Information technology — Biometric system-on-card — Part 1: Core requirements ISO/IEC 17839-1:2025

Publication date:   Nov 7, 2025

Scope

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.
