ISO/IEC 19794-4 (FIR) - The Fingerprint Format Behind Secure Application

How does a fingerprint scanner capture your unique personality? The answer lies in the ISO/IEC 19794-4 technical standard also known as FIR (Finger Image Record). This blog post reveals the secret behind FIR, explaining the role it plays in fingerprint security and how it ensures proper data exchange between devices. 

The FIR format specifies how this fingerprint image is stored, ensuring consistent data structure across different fingerprint scanners and recognition systems. Here's what FIR captures:

FIR allows fingerprint scanners from various manufacturers to capture and store fingerprint images in a universally understood format. This enables:

FIR serves as the foundation for secure fingerprint-based applications like:
