The Verge
Facial recognition has been heralded as a secure way to confirm your identity on your phone or at payment terminals, and with features like Face ID on your iPhone, it sometimes seems like the tech really is more secure than other options. But the tech isn’t infallible, as public facial recognition terminals can still be fooled with just a mask, as some recent experiments have shown.
