Chipsets & Sensors

High definition sensing – UPEK high definition sensing captures the
highest quality images for secure authentication and a convenient
user experience.

Capacitive Sensing – UPEK sensors measure feedback
capacitance determined by the presence of 3-dimensional
ridges and valleys of a fingerprint.

Active Pixel Sensing – Each pixel has its own amplifier for crisp, detailed images.

Live Layer Sensing - UPEK sensors sense both the surface and the subsurface, or “live layer”, of the skin.

Large Image Area – UPEK sensors scan larger finger areas to enable more accurate authentication and a more accommodating user experience.

Rugged – High sensitivity pixels enable the use of a hard protective coating and the ability to withstand high levels of electrostatic discharge (ESD) for long, trouble-free operation.

Minutiae algorithm – UPEK algorithms extract unique features called “minutiae” from the fingerprint image. Minutia-based matching preserves privacy and minimizes the information that must be stored or transmitted. It is not possible to recreate a fingerprint from the minutia data.

Digital ID Hardware Engine – UPEK’s Digital ID Hardware Engine is a secure processing environment for all biometric operations. Using secure processing protects privacy and insures that biometric results are trustworthy, secure, and accurate. All critical processing is protected from hackers, software viruses and other malware.

Security and privacy protection - Reliably recognizes authorized individuals and prevents unauthorized access

Convenience and ease-of-access - Consistently recognizes enrolled users over time and in various environments

Benefits for all - Allows virtually anyone to enjoy the security and convenience benefits of fingerprint authentication

TCS3-TCD42 TouchStrip Fingerprint Authentication Solution

TouchStrip® Fingerprint Authentication Solution (TCS3-TCD42)
The TouchStrip Fingerprint Authentication Solution consists of a TouchStrip Fingerprint Sensor (TCS3) and the Digital ID Hardware Engine (TCD42). The TouchStrip Fingerprint Authentication Solution offers the security of hardware-based biometric authentication necessary to protect PCs and peripherals from hacking attempts.

TCED - TouchStrip Fingerprint Authentication Module

TouchStrip® Fingerprint Authentication Module (TCED)
The TouchStrip Fingerprint Authentication Module (TCED) is a complete biometric subsystem based on the TCS3 sensor and TCD42 Digital ID Engine. Everything is mounted on a compact PCB including a USB-ready flex cable connector, making it easy for designers to integrate biometrics into PCs and peripherals.

TCS4 – TouchStrip™ Fingerprint Sensor for Mobile Solutions

TouchStrip® Fingerprint Sensor (TCS4)
The TouchStrip Fingerprint Sensor (TCS4) is a cost-effective swipe sensor with a small form factor that provides PC users the convenience of user authentication and personalization.
