[br][br][br]Third party image reference[br]This sensor made by QuantumCall is an ultrasonic fingerprint sensor that is slightly different from the common fingerprint.[br][br]It can work inside the fingerprint display. It is quite different from the fingerprint normal fingerprint. It has been used in technology that changes the touch of our finger into sound and creates its 3D image and thus works as fingerprint.[br][br]

[br][br][br]Third party image reference[br]This fingerprint can work even when your hands are wet, for the first time in the , the use of ultrasonic fingerprint for the first time, this technology is very expensive in the display and you will not get this technology to look in cheap phones.[br][br][br]

[br][br][br]Third party image reference[br] also had a mobile phone with its display fingerprint sensor but the fingerprint sensor used in it is not an ultrasonic fingerprint sensor but it uses an optical fingerprint sensor which saves the fingerprint image of our finger and saves it to the optical fingerprint sensor.[br][br][br]

[br][br]Third party image reference[br]Hacking is easy but ultrasonic fingerprint sensor is quite safe If speed, ultrasonic fingerprint sensor is very fast, but the biggest drawback of ultrasonic fingerprint sensor is that it does not work when applying tempered glass because after which the inside of the sound display inside our fingers is present in the display Ultrasonic sensors will not be able to reach. Thereby mobile will not be unlocked.[br][br]By the way, ultrasonic display fingerprint sensor is fast and safe with optical fingerprint sensors, but the special thing about the optical fingerprint sensor is that it can also be unlocked with tempered glass.
