Ultrasonic vs Optical Fingerprint Scanner: Which is Better?

Fingerprint scanners have become a crucial component of modern smartphones, providing an additional layer of security and convenience. Two popular technologies used in fingerprint scanning are ultrasonic and optical. In this blog post, we'll delve into the differences between ultrasonic and optical fingerprint scanners, exploring their strengths and weaknesses to determine which one is better.

Ultrasonic Fingerprint Scanner

Ultrasonic Fingerprint Scanners use high frequency sound waves to penetrate the epidermal ie the outer layer of the skin. The thermal scanners sense the temperature differences on the contact surface, in between finferprint ridges and valleys.

Pros of Ultrasonic Fingerprint Scanner

Ultrasonic scannners use high frequency sound waves to create a 3D map of the fingerprint, making it secure and difficult for hackers to replicate. Ultrasonic scanners can also detect slight variations in fingerprint patterns, resulting in higher accuracy. Lastly Ultrasonic fingerprint scanners are less prone to wear and tear, ensuring consistent performance over time.

Cons of Ultrasonic Fingerprint Scanner

Ultrasonic fingerprint scanners are generally more expensive to produce than optical scanners. And it may not be compatible with some devices and their operating systems.

Optical Fingerprint Scanner

Optical Optical Fingerprint Scanner captures your fingerprint by using light reflected on your finger,that is why your phone lights up wwhen you place your finger against your fingerprint sensor.

Pros of Optical Fingerprint Scanner

Optical Fingerprint Sensor are Widely compatible which enables it work with a broader range of devices and operating systems. Some devices that uses Optical Fingerprint Sensors are Oppo and the Goggle Pixel models.

Cons of Optical scanners

The use of light to capture fingerprint makes them more vulnerable to hacking. Sometimes Optical scanners can struggle with variations in fingerprint patterns, leading to lower accuracy. Lastly Optical scanners require regular cleaning which makes it hard to maintain.

Comparison

Ultrasonic fingerprint scanners offer superior security and accuracy but come at a higher cost. Optical scanners are more affordable and widely compatible but compromise on security and accuracy.

Conclusion

While both ultrasonic and optical fingerprint scanners have their strengths and weaknesses, ultrasonic scanners offer better security and accuracy, making them the preferred choice for those prioritizing.
