ISO/IEC 30106-1:2016 specifies an architecture for a set of interfaces which define the OO BioAPI. Components defined in this part of ISO/IEC 30106 include a framework, Biometric Service Providers (BSPs), Biometric Function Providers (BFPs) and a component registry.

NOTE Each of these components have an equivalent component specified in ISO/IEC 19784‑1 as the OO BioAPI is intended to be an OO interpretation of this part of ISO/IEC 30106.

For this reason, this part of ISO/IEC 30106 is conceptually equivalent to ISO/IEC 19784‑1. Concepts present in this part of ISO/IEC 30106 (for example, BioAPI_Unit and component registry) have the same meaning as in ISO/IEC 19784‑1. While the conceptual equivalence of this part of ISO/IEC 30106 will be maintained with ISO/IEC 19784‑1, there are differences in the parameters passed between functions and the sequence of function calls. These differences exist to take advantage of the features provided by Object Oriented Programming Languages.
