The scanner is designed for capturing complete fingerprints of two fingers simultaneously.
The scanner can be used in identification systems with two, four, and ten fingerprints registration.
The rolling procedure is excluded due to placing fingers into cylindrical indentations on the sensor surface that simplifies fingerprinting process greatly.
The fingerprint dimensions are much more than the area obtained on the scanner with a flat prism.
A possibility of fingers muddle is practically excluded.
