In-Display Fingerprint Sensors: The Users' #1 Choice to Unlock Smart Devices

Save your users the hassle of re-entering PINS and passwords! Fingerprint scanners have become the preferred choice for biometric authentication. This trend is everywhere in everyday life. From unlocking our phones to securing payments to unlocking access to accounts, this technology has enriched our lives with its convenience. An easy and safe solution needing only the user's finger, the fingerprint scanner has become a part of our everyday lives.

In 2021, 9to5Google ran a poll:

The #1 desired choice to authenticate on smart devices was the in-display fingerprint sensor.

Achieve a Bezel-less and Waterproof Smartwatch Design

The C610 is optical. Optical scanners surpass capacitive and ultrasonic sensors by being capable of scanning a finger image through thicker OLED display glass (2.5D glass or thicker) with

high resolution and high performance.


Choosing an optical fingerprint reader lets your module seamlessly

integrate into a clean under-glass, under-display water-proof design.

No Need to Sacrifice on Design:
An Easy Implementation that Makes Sense

Save on manufacturing cost because there is no need to thin out your device's display screen or add bezel to accommodate for this fingerprint sensor.


This optical fingerprint scanner sensor rests invisibly under the screen's surface, behind your OLED or AMOLED display. The miniscule energy consumption of the sensor means saving battery life.

The additional sleep mode allows for greater energy savings.

The tiny C610 sensor keeps the weight light.
