IDEX has a wide range of fingerprint sensor products for applications in the card, mobile and IoT markets. The company offers a complete touch sensor portfolio consisting of the most accepted capacitive sensing techniques in circulation today, including off chip sensing and conventional capacitive silicon sensing. IDEX is the only company in the industry to offer both these capacitive technologies.

Both product categories within the IDEX portfolio of touch sensors are complete system solutions including image delivery hardware, tightly coupled software control and matching algorithm, trusted execution environment and FIDO™ compliant reference designs.

IDEX collaborate with tier-one manufacturing partners for production, and the products are backed by one of the industry’s strongest IP portfolios.


IDEX is one of only two vendors to offer off-chip capacitive fingerprint sensors. The IDEX off-chip sensor solutions portfolio offer a highly customizable variety of sensor form factors, high biometric performance and compelling cost points.

Off chip sensing separates the sensor ASIC chip from the sensing substrate resulting in higher image fidelity, superb noise immunity and market leading wet – dry finger usability. In addition, the off chip technology offers superior flexibility in sensor design, including using different substrate materials tailored to specific applications.

The current family of IDEX’s off chip sensor is called Eagle. The Eagle sensor portfolio is available in customized variations for applications in cards, mobile and IoT. For cards the off chip technology enables a thin and bendable polymer sensor withstanding bending, for mobile the sensor has a very compelling cost point for medium sized sensors, and in IoT the sensors allow for integration in resource constrained applications.

IDEX’s off chip sensor systems are closely coupled hardware – software solutions, with highly optimized image delivery and matching algorithms that result in best in class security strength and outstanding usability. Achieving the highest SNR values in the industry allows IDEX’s off-chip products to perform exceptionally well with difficult fingers, through thick coatings or within high noise environments. One of the only sensors in the market that eliminates common mode noise at the front end via hardware vs. back end post processing techniques. The result is broad demographic coverage, solid performance with difficult wet & dry fingers and transaction class security.

On board encryption blocks provide full transport level security between the sensing system and the host processor and comes with Trusted Execution Environment software reference design and support. Eagle is FIDO-Ready™.


IDEX’s conventional silicon product is called Cardinal, and is developed in partnership with CanvasBio . The Cardinal products have the smallest silicon footprint in the market for space challenged mobile fingerprint sensing applications. The current versions of the Cardinal, the Cardinal Q and Cardinal N, are ultra-small form factors enabled by state of the art matching algorithm technology that is able to exploit very small images into quality match results. A completely tuned hardware – software solution, pre-optimized to allow ease of integration into a variety of applications. Cardinal products also support extremely fast image capture and match times enabling true ‘tap ‘n go’ applications.

In Q1 2017 IDEX is launched a new series of glass and ceramic touch sensors for mobile applications. The new fingerprint sensor solutions are based on the company’s silicon-based Cardinal architecture with enhanced imaging performance to replace conventional coating by sensing through glass and ceramic covers.
