Comment Audio Authentication (Score 0) 55
Authentication using various methods of audio modulation and demodulation has been around for more than 10 years. My company alongside 2 others were the leaders in developing and patenting this tech. While I haven't looked extensively at how they are doing it, his video does mention something about using ultrasonic frequencies which our patents don't cover but BeepCard's (another Israeli start-up) patents very much do so. I'm sure they'll be looking into this pretty soon.
