I plopped into the front seat, expecting to laugh in the face of the machine attempting to measure my age, gender, emotional state, and comfort level all through infrared cameras and other sensors. But sitting expectantly in the car, equipped with French automotive software company Valeo's Smart Cocoon 4.0 system, I was flabbergasted when it pinpointed my exact age. Getting that number right made me trust the car's biometric system more than I probably should have, even as tools that measure your heartbeat, track your eyes, head position, voice, and more enter vehicles everywhere. At CES this year, driver and passenger monitoring kept popping up. It's a preview of what will become commonplace in the driver's seat in the coming years.

Samsung has now admitted that its Galaxy S8's facial recognition technology is not fit for carrying out mobile payments. The feature is said to be not as secure as fingerprint and iris recognition, and it would take time before it could be used in authenticating Samsung Pay transactions. On Tuesday, someone from Samsung told The Investor that the facial scanning technology of the Galaxy S8 and S8 Plus is not secure enough for mobile payments. The same source stated that the South Korea giant needs more than four years before the feature could be ready to handle mobile payment transactions. "In order for facial recognition to be solely used for financial transactions, it would take more than four years considering the current camera and deep learning technology levels," the source was quoted as saying.
