ISO/IEC 29141:2009 specifies requirements for the use of ISO/IEC 19784-1, as amended by ISO/IEC 19784-1/Amd.1 (BioAPI) for the purpose of performing a tenprint capture operation.

It specifies a biometric data block format that is used to interact with a BioAPI framework [and hence with biometric service providers (BSPs)] to support an application wishing to perform a tenprint capture.

It specifies a capture control block and a capture output block that conforming BSPs are required to support if they conform to ISO/IEC 29141:2009.
