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.
