Fingerprint Sensors

FPC’s developed various kind of Fingerprint Components and Modules and fingerprint sensors, such as touch fingerprint sensors, swipe fingerprint sensors and area fingerprint sensors used for authentication software and extraction of fingerprint characteristics and comparison with enrolled templates (also called bio-engine).A silicon coated fingerprint SENSOR offers a unique and practical approach to electronically recognizing and verifying a person’s identity, these sensor ensuring the best possible biometric authentication. Fingerprint sensor embedded on Smartphone and many other card market applications such as ID & smart card and the Internet. FPC range offers a cost effective best in class performance sensor for production.

Fingerprint Sensors

FPC’s sensor contains tens of thousands of small capacitive plates, each with their own electrical circuit embedded in the chip. When the finger is placed on the sensor extremely weak electrical charges are created, building a pattern between the finger’s ridges or valleys and the sensor’s plates. Using these charges the sensor measures the capacitance pattern across the surface. The measured values are digitised by the sensor then sent to the neighbouring microprocessor.

These entire FPC sensors follow own method HSPA (High Sensitive Pixel Amplifier) which allows each pixel element in the sensor to detect very weak signal, which improves image quality for all types of fingers.

Ashtopus technologies provides high performance sensor with leading cost position, targeted towards high security and integrated on smart device used for many application areas effectively. Fingerprints are a unique way to provide high and unique identification -security features.

Fingerprint biometric sensor performs the following operations:


This process is initial stage an operation where the end-user scans his fingerprint by sweping it across the Finger chip sensor, providing a fingerprint signature reference (template).


A method to identify accurate matching of the newly acquired fingerprint against the templates stored in the board’s memory during the enrollment procedure, used to validate user authentication.


Matching of the fingerprint image against the correct template within a database of previously acquired templates.

These three basic functions can then be used in any application requiring authentication to grant rights to a user, or to change criteria of the user’s profile.
