Fingerprint's cutting-edge biometric T-Shape sensor ensures that users face minimal delays when accessing secure areas on their company sites, or logging onto digital systems. With its self-learning ...

If you need to measure a distance, it is tempting to reach for the ubiquitous ultrasonic module like an HC-SR04. These work well ... So maybe try an IR time of flight sensor.

But what makes it different from the optical fingerprint sensors and why is it better? Read on to find out. Ultrasonic fingerprint scanners are usually only seen in premium phones like the Galaxy ...

The OnePlus 13 will have an ultrasonic fingerprint sensor, with a "super intuitive" position. As any other ultrasonic fingerprint scanner, this one will work with wet fingers, while unlocking at ...

After an initial calibration with ultrasonic sensors (HC-SR04), it is possible to select motor speed, range of movement in both directions and the number of time it repeats the command. The collector, ...

While the overall unlock experience and speed rely on more than just the hardware, an ultrasonic sensor is always going to be better than an optical sensor. The new ultrasonic fingerprint scanner ...
