Built-in Intelligence

Finger Capture

Compatible with a wide range of fingerprint scanners from leading manufacturers, ensuring versatile and sensor-independent biometric data acquisition.

Minutiae Extraction

Efficiently extracts minutiae and proprietary templates from fingerprint images, producing compact templates (less than 148 bytes) for fast matching.

Liveness Detection

Presentation Attack Detection (PAD) to protect against spoofing using fake fingerprints, gummy fingers or printed images.

NFIQ Quality

NIST Fingerprint Image Quality (NFIQ) scoring to assess and ensure optimal image quality before extraction and matching.

1:1 Verification

Precise one-to-one fingerprint comparison for reliable identity verification in access control and authentication scenarios.

1:N Identification

Ultra-fast one-to-many search capable of matching millions of fingerprints per second for large-scale identification.

Core Technology

Our fingerprint recognition engine combines optimized algorithms with standardized template formats, delivering outstanding performance across all platforms. Templates among the smallest on the market enable deployment on resource-constrained devices including smart cards.

NIST MINEX III Evaluation

id3 Technologies fingerprint algorithm demonstrates excellent accuracy and interoperability in the NIST MINEX III evaluation, testing INCITS 378 template generators and matchers for the U.S. PIV program.

Pooled 2 Fingers iVerification using two combined fingerprints (e.g. left + right index). Results are pooled across all finger pairs in the dataset.
FNMR @ FMR ≤ 10-2 iFalse Non-Match Rate when the False Match Rate is at most 1%. In other words: allowing at most 1 impostor per 100 attempts, only 0.026% of legitimate users are incorrectly rejected.
0.00026
id3+14A1 — Sept. 2024
Native 1 Finger iVerification using a single fingerprint. A stricter test since there is less biometric data available for matching.
FNMR @ FMR ≤ 10-4 iFalse Non-Match Rate when the False Match Rate is at most 0.01%. A much stricter threshold: at most 1 impostor per 10,000 attempts.
