ISO/IEC 17839-1:2014 establishes

• functional architecture of a Biometric System-on-Card
• definition of type S1 (fully ISO/IEC 7810 compliant) and type S2 implementation of a Biometric System-on-Card
• sensor types in a Biometric System-on-Card
• minimum requirements to a Biometric System-on-Card with respect to
• discriminative power (i.e. biometric accuracy criteria)
• interfaces
• power supply options

The following aspects are out of scope of ISO/IEC 17839-1:2014:

• off-card biometric comparison, storage-on-card
• work-load sharing implementations
• detailed specification and configuration of individual components

ISO/IEC 17839-1:2014 provides a functional architectural description of a Biometric System-on-Card and describes how the interfaces are mapped using existing commands and data structures from other International Standards.
