FASTfinger® SHERLOCK 2018-02-28T12:25:56+00:00

FASTfinger® SHERLOCK is the world’s thinnest, lightest FBI certified two-finger scanner to capture single flats, rolls, and dual flats at 500 PPI.

The scanner’s size is 12mm thick and weighs only 60 grams. FASTfinger® SHERLOCK is designed in the thinnest form factor and impervious to latent prints caused by artifacts, oil, and moisture. It captures high-quality fingerprints in any difficult conditions, especially excellent at dry fingers, and performs in direct sunlight. Supporting various OS such as Windows, Linux, and Android, and maximizing mobility of design, FASTfinger® SHERLOCK is the best device to apply to mobile environment where small size and light weight are valuably considered.

FBI Appendix F Certification

FASTfinger® SHERLOCK is FBI Appendix F certified scanner that uses LES (light emitting sensor) technology. FBI Appendix F certification, which is image quality specification for collecting fingerprint images, is the standard applied to both flat and rolled scans. FBI certified fingerprint scanners mean that they are following the strict standard to meet image quality required for fingerprint enrollment or authentication.

Ultra-small Form Factor

FASTfinger® SHERLOCK scanner size is only 59.5 x 61.2 x 12.0 mm and weighs ultra-light 60 grams. The smallest, lightest weight form factor means that FASTfinger® SHERLOCK can cover various cases in which real-world users demand it for enrollment and authentication. FASTfinger® SHERLOCK is an ideal device not only for desktop, but for integrated purpose including mobile devices and kiosks.

Excellent Durability

FASTfinger® SHERLOCK is designed to withstand harsh environments with minimum maintenance. FASTfinger® SHERLOCK using IP65 rated bezel passed tests on outer durability and resistance, preventing inflow of water and dust.

Structural Prevention of Various Fake Fingers

FASTfinger® SHERLOCK is capable of structurally preventing intentional tries to enroll or verify fake fingers, because the scanner based on LES technology does not have any response to various kinds of fake fingers including paper, rubber, gelatin, silicon, latex, and so on.

High-quality Images for Various Finger States

The state of a fingerprint enrolled on the livescanner can be discern as wet, dry, weak, and dirty. FASTfinger® SHERLOCK collects 500 PPI high quality images, as its LES technology reduces the effects of various finger states.

High-quality Images with Rare Effects of Marks or Stains

Unlike other optical scanners, FASTfinger® SHERLOCK based on LES technology is capable of collecting high-quality images from stained fingerprints, minimizing the effects of latent prints caused by dirt, oil and moisture, and avoiding halo effect.

Efficient Power Consumption

FASTfinger® SHERLOCK operates by low power consumption. The scanner requires power of <200mA during full scanning mode and 2mA during suspend mode. The low power consumption allows FASTfinger® SHERLOCK to apply to wide areas including mobile environment where a scanner should work in the power of a laptop or battery.

No Impact from Direct Sunlight during Scanning

Capturing mechanism of the light emitting sensor has a principle of operating with no impact of outer light. Therefore, FASTfinger® SHERLOCK is not affected by any indoor light. It captures high-quality images even under direct sunlight.

Minimum Maintenance

FASTfinger® SHERLOCK does not apply silicon pad that some models in the market use, so it has no maintenance cost led by the silicone pad. Also, prism optical scanners need to clean due to latent prints or artifacts on the prism caused by repetitive inputs, but FASTfinger® SHERLOCK is so convenient that it can collect high-quality images from repetitive inputs.
