    Wsq PNG BMP JPEG Image Format Small Size Desktop Fingerprint ...
    A WSQ (Wavelet Scalar Quantization) fingerprint scanner is a biometric device that captures and compresses fingerprint images using the FBI-standard WSQ algorithm, which efficiently reduces file sizes (often 15-20x) without losing critical image quality. These scanners are used for law enforcement, border control, and secure identification, with many featuring FBI Appendix F certification. 
    Key Features and Aspects of WSQ Scanners 
    • FBI Certification: WSQ is the standard for 500 ppi fingerprint images, with many devices, such as the Realscan SG10, meeting stringent FBI image quality standards.
    • Compression Advantage: The algorithm maintains high-quality images while minimizing storage needs, reducing a standard

       500 ppi image down to about
      30
      KB
      .
    • Applications: These scanners are vital for high-accuracy applications, including electronic fingerprint exchange, background checks, and national ID systems.
    • Software and SDKs: Companies provide specialized toolkits, such as the Aware WSQ1000, to enable fast compression and decompression for developers.
    • Hardware Variants: WSQ support is available across various hardware, from mobile, handheld devices to robust, high-volume scanners like the Grabba X-Series.
    • Format Conversion: Tools exist to convert RAW images captured by scanners into the compressed WSQ format.
    • Comparison to Other Formats: Unlike standard JPEG compression, WSQ avoids "blocking artifacts" and maintains ridge details crucial for identification. 
    For software development, NIST provides a certification procedure to verify the compliance of WSQ implementations.
