While most of the media focused on the cost of the Samsung Smartphone folding, writer Simon Scano focused his attention on the company's new ultrasound fingerprint reader, which Scano hopes will be adopted by other smart phones.

"My phone Samsung S10 and S-Plus have a fingerprint reader that uses ultrasound technology, not optical," he said in a report published on the Android Web site. "Both are quite different.

This sensor, manufactured by Qualcomm, uses ultrasound technology that is different from the optical fingerprint sensor, where the new technique sends a sound wave that flattens when it "connects" to the finger.

The wave is measured by a program that creates a three-dimensional image of the finger. Once recorded, the device will only compare this recorded digital fingerprint.

So far, this technique looks similar to the previous technique, but what makes this process more accurate is the ability of the sound waves to penetrate the subcutaneous layer, and to read more details from the fingerprint reader, so any imitation of your digital fingerprints will not unlock your smartphone.

Qualcomm also said that, as well as being more accurate, this technique is able to detect the blood flow in the finger, so that it becomes impossible to deceive.

In addition, Samsung has confirmed that the Galaxy S sensor can activate the lock of mobile phone services operated by the Blockkin. In other words, the smartphone is able to protect the encrypted currency portfolio, which is a clear indication of the security of this technology.

"In order to ensure full operation of the Ultrasonic Fingerprint Reader for the Galaxy S10 and S10 Plus, Samsung strongly recommends the use of original Samsung screen protectors only.
