1 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.
