Integrated Biometrics Sherlock claims to be the world’s smallest, lightest and one of the most accurate FBI Appendix F certified two-finger roll scanner. Equipped with IB’s patented Light Emitting Sensor (LES) sensor technology, Sherlock promises to produce the highest quality fingerprint images among its peers.

IB Sherlock is versatile enough to capture 1, 2, and 10-finger enrollment, dual flat print and single finger roll scans. Its performance does not fluctuate, no matter how challenging the finger skin type is. If you have challenging environmental conditions and need a fingerprint scanner that can consistently perform even with difficult-to-scan finger skin types, there is no better option than IB Sherlock.

Sherlock is not only an Appendix F and FBI Mobile ID (FAP 45) certified dual finger reader, it is also Secure Web Fingerprint Transmission Plus Enrollment (SWFT+) compatible, which means that you can use this device for the DoD (Department of Defense) background check applications.

FBI certified

Sticking to FBI’s image quality specifications can be challenging even for high quality fingerprint scanners. Adhering to Appendix F image quality specification can particularly be difficult as it consists of the most stringent image quality specifications. FBI requires manufacturers to stick to these standards to ensure consistency, standardization and to ensure inter-operability, if they want their scanners to be used in FBI applications.

IB Sherlock adheres to Appendix F and FBI Mobile ID (FAP 45) quite easily. In fact, Integrated Biometrics is the first and only company in the United States that has developed an FBI FAP 45, appendix F certified scanner, which is not based on traditional optical technology (Total Internal Reflectance) using a prism.

Patented LES technology

Developed and produced by Integrated Biometrics, patented LES (Light Emitting Sensor)film offers unmatched operability. LES technology enables IB Sherlock to keep up its performance in harsh environmental conditions such as direct sunlight as well as challenging finger skin conditions such as dry or moist fingers. Integrated Biometrics’ sensor technology is based on an electroluminescent (LES) film. This film contains non-scale luminescent particles dispersed across the film.

When finger is placed on the sensor surface, these luminescent particles illuminate as the friction ridges of the finger skin completes the electric circuit required for it. This narrow wavelength light illuminates the pattern of friction ridges and produces a high resolution image, which is captured by a digital TFT (Thin Film Transistor)camera. The resultant image has the resolution of 500 pixels per inch.

Superior anti-spoofing

Conventional optical sensors capture the image of the skin surface using total internal reflectance with a prism. However, LES film image capture is based on the physical contact of the live finger’s friction ridges with the sensor surface. Contact with live finger completes the low level electric circuit required to illuminates the ridges and produces a perfect fingerprint image.

Being based on localized illumination due to liveness characteristics, LES film will not illuminate for a spoof or fingerprint replica, since they lack the liveness features required to complete the electric circuit. This automatically makes Integrated Biometrics Sherlock highly immune to spoofing as its sensing technique is inherently based of liveness characteristics.

Leftover prints can also be a problem with ordinary optical sensors, in which fingerprints left behind by other users may impact the fingerprint image quality and impact the performance of the scanner. Leftover prints can confuse the system and may result in false positives and false negatives. The problem of left behind prints is automatically eliminated when you choose LES sensor as these sensors do not entertain leftover prints.

Durable and compact

Despite being a highly accurate two-finger roll scanner, IB Sherlock does not compromise on the durability front. This masterpiece would never break a sweat to endure some of the toughest and most challenging environmental conditions.

IB Sherlock’s sensor can not only resist abrasion, but also helps keep the size of the device compacter by 90-95% and lighter than the optical scanners, thanks to the patented LES film technology. This scanner is particularly suited to the mobile applications where minimal size and weight carries a signi­ficant value. Tested on United States military environmental testing standards like MIL-STD-810, Sherlock is built to survive extreme environmental conditions.


  • Sherlock meets the stringent image quality conditions laid by FBI Appendix F, making it one of the worthiest options in certified mobile scanners.
  • Impeccable fi­ngerprint capture in standalone applications as well as in combination with commercial smartphones and tablets.
  • Equipped with patented LES film technology that can withstand harsh environmental conditions as well as difficult to scan finger skin types.
  • Weighs just 60 grams, an extremely light weight scanner in certified FAP 45 space.
  • Capable of capturing two finger full prints and single finger roll scan.
  • Ideal to use with mobility focused applications like mobile computers, hand-held devices, smartphones, and tablets.
  • Ergonomically designed, easy to use.
  • LES can easily avoid leftover / latent prints that may be present on the scanning surface.
  • Energy efficient. Mobile and handheld applications may heavily rely on battery power and energy efficient hardware.

Perfect FBI certified scanner for you

Integrated Biometrics Sherlock can easily handle difficult-to-scan finger skins types, in which ordinary scanners would easily give up. It can scan fingerprints from challenging finger skin conditions such as dry, moist, aged or scarred fingers even in extreme environmental conditions such as direct sunlight.


Best suited for field applications that require sensors with high level of durability and ruggedness. Optical scanners have failed to deliver the required efficiency in such applications. This is where Sherlock brings some hope by being compact, rugged as well as power efficient at the same time, making it a one of the best scanners in the certified scanners’ market.


Performance of optical scanners is affected by the leftover prints on the scanning surface and needs to be cleaned after each scan to get rid of them. Sherlock, on the other hand, can let unintentional or latent prints go unrecognized without having any negative impact on its performance. Cleaning latent prints can be a cumbersome job in high volume back to back scanning situations. Ability to let latent prints go unrecognized is inherent in LES film technology, which boosts its usability enormously.


LES (Light Emitting Sensor) technology leverages a sensor based on an electroluminescent (LES) film to create the fingerprint image. The technology has already stirred the market and attracted some high value clients. Being lightweight, compact and power efficient, Sherlock offers incredible value for money.


Built to last, Sherlock is a durable scanner with IP65 ingress protection rating for sealed bezel to scanning surface. Unlike optical scanners, it can work in direct sunlight and has no problem in scanning dry or dirty fingers. Weighing just 60 grams and with small footprint of mere 2 65.4 mm x 61.6 mm x 14.3 mm, Sherlock can be deployed particularly in mobile and handheld applications.


Small or powerful? Ergonomic or Accurate? Why trade-off when you can have them all? Sherlock tries to tick all the boxes with its compactness, power efficiency, ergonomics and accuracy, saving you from trade-offs. Being the world’s smallest scanner with Appendix F FAP 45 FBI certification yet at a competitive price, Sherlock is a bang for the buck.
