Galaxy S10 ultrasonic fingerprint scanner fooled by 3D printed mark

After years of delays, Samsung finally jumped aboard the fingerprint-on-display (FoD) train but it may be costing users more than they're willing to pay. Thanks to its new "Infinity-O" punch hole display, it has made face recognition practically useless as a security feature. Now there is at least one experiment that tries to prove how its ultrasonic fingerprint sensor is actually less secure than regular optical ones.
