The U10-SF is an advanced, stand-alone fingerprint recognition system that captures and stores fingerprint data and identifies or verifies registered users. It is the newest member of SecuGen’s Unity OEM Modules: all-in-one, stand-alone fingerprint systems designed to function entirely without an external PC.


With its ultra-slim and rugged design, the U10-SF can be integrated into access control units, door locks, ATMs, handheld devices, laptops, point of sale equipment, industrial equipment and many other kinds of products especially where space is limited. It can communicate with external devices and is interoperable with data input from SecuGen USB fingerprint readers for a wide variety of implementations.


The U10-SF consists of the SecuGen U10, an FBI-Certified FAP 10 fingerprint sensor, combined with a programmable Single-Board Computer (SBC) that includes onboard CPU, SDRAM, and flash memory.

Features of Fingerprint Sensor


  • Rugged, high image quality fingerprint sensor that is FBI Certified (PIV, FIPS 201, Mobile ID FAP 10 Compliant). Meets FBI Image Quality standardsThe fingerprint sensor was certified by the FBI as tested and in compliance with the FBI’s Next Generation Identification (NGI) Image Quality Specifications (IQS). The review of the test data was conducted by the FBI / Criminal Justice Information Services Division / Global Operations Section, as part of the Biometric Center of Excellence.
  • Built upon patented technologies that allow rapid capture of high-contrast, low-distortion fingerprint images
  • Smart Capture ensures high quality imaging even from traditionally difficult fingerprints, such as dry or moist fingers, as well as under very bright conditions, such as outdoors in sunlight
  • Auto-On for automatic detection of a finger when placed on the sensor

Features of Built-in Processor Board (SBC)


  • Fingerprint Management System (FMS) software that works right out of the box
  • Open Linux OS that lets you develop custom applications running on the device
  • Large fingerprint template storage capacity and support for SG400, ISO/IEC 19794-2, and single view ANSI INCITS 378-2004 templates
  • NIST MINEX Certified and FIPS 201 Compliant embedded fingerprint algorithms for template generation and matching
  • High-speed fingerprint matching in verification mode (1:1) or identification mode (1:N, using built-in SecuSearch Engine)
  • Serial (CMOS) interface for external I/O
  • Interoperable with data input from SecuGen USB fingerprint readers to support a wide variety of implementations
  • Responds to serial commands that use the same protocol supported by SecuGen’s SDA04P-series OEM modules

Advantages of U10-SF


Non-optical fingerprint sensors based on capacitive or semiconductor technology are frail in comparison with the U10-SF, which can withstand extreme environmental conditions, heavy use, as well as external shock, scratches and impact. This makes it an ideal solution for a diverse range of applications, especially those used in outdoor, rugged, and high-traffic environments. Its ultra-slim size makes it smaller than most other optical fingerprint devices so that it can be more easily integrated into a wider range of applications where space is limited.

Typical Applications


The U10-SF was designed to satisfy today’s growing need for security applications that require standalone, embedded fingerprint systems such as:


  • Physical access control systems
  • Door-lock systems (indoor/outdoor)
  • Time & attendance systems
  • Cabinet safes and vaults (gun safes, safe deposit boxes)
  • Vehicle access control
  • Automatic teller machines (ATM)
  • Point-of-sale machines (POS), kiosks
  • Verification of credit cards/smart cards
  • Secure network systems
  • Laptop and tablet integration
  • Handheld and mobile devices

The Unity OEM Developer Kit provides development tools, including an interface development board, software and documentation, to assist developers with the integration of the Unity OEM module. The Developer Kit also includes APIs and data conversion modules to help expand the capabilities of your fingerprint biometric system with the following functions:


  • Register, update and delete user profiles
  • Verify or identify user
  • Manage user database
  • Control system settings (brightness, exposure, gain, security levels, quality threshold, etc.)
  • Test all functions
  • Interface with PC and SecuGen USB fingerprint readers
