The speaker in the video was extremely difficult for me to understand but the idea seems quite clever.
What I'm most surprised about is just how well it actually works... I did not think such EM fluctuations would be usably detectable from several meters away... but I suppose this may be moreso due to improper/lack of shielding in the first place, which I would think should be easily fixable in most products to mitigate this type of detection.
