Fingerprint API

API that provides functions to scan, extract, and compare fingerprint template data.

• BS2_ScanFingerprint: Scans a fingerprint from a device and extracts template data.
• BS2_ScanFingerprintEx:​ Scans a fingerprint from a device and extracts template data and scan image scores.
• BS2_VerifyFingerprint: Compares the template data to check if it is the same finger.
• BS2_GetLastFingerprintImage: Extracts the image of the last scanned fingerprint using the BS2_ScanFingerprint API.
• BS2_GetFingerTemplateQuality: Checks the quality score of the fingerprint from the fingerprint template data.
