Create the fingerprint identification high-speed buffer. As for 1:N identification, this function must be first called so as to obtain the fingerprint identification buffer handle.
ZKFinger 1:1 low-speed verification speed is rather slow (about 30ms for PII 233), so fingerprints of 1:1 genre added to the buffer by calling the function AddRegTemplateToFPCache can not be too many; otherwise, the verification speed will be impacted. By IsOneToOneTemplate, we can judge whether the fingerprint is of1:1 type ornot. At the same time multiple buffers can be created for group comparison and others.
