IDKit SDK is designed to generate Innovatrics' proprietary fingerprint templates, it supports 1:1 verification and also 1:N fast identification as well as database storage.
ANSI&ISO SDK is designed to generate and match standardized fingerprint templates but supports only 1:1 verification with no additional features.
As for interoperability between IDKit SDK and ANSI&ISO SDK, both SDKs can create templates in their respective template format from the original fingerprint image. IDKit SDK can additionally export templates in the format used by ANSI&ISO SDK, but import of ANSI&ISO SDK templates into IDKit SDK is not supported.
