​Hyundai has committed to becoming the world's first auto manufacturer to ship cars that open and start without any keys or smartphones whatsoever. The 2019 Santa Fe SUV will use fingerprint sensors for its door locks and ignition.

​Although 3D printers are able to produce some amazing objects, they can also crank out counterfeit goods, illegal firearms, and other not-so-nice creations. Soon, if someone is suspected of making such items, it could be possible to match the objects to that person's printer.

Let's face it – thieves know that high-end SUVs like the Bentley Bentayga are likely to contain stuff worth stealing. The automaker's Mulliner division obviously realizes that, because it's introducing an optional biometric secure stowage unit for the vehicle.

Vivo introduced a novel concept smartphone earlier this week. Not only does the Apex almost get rid of bezels from the front, but sounds belt out from the screen itself, half the display is a fingerprint scanner and the front camera pops up from inside the body when needed, and disappears when not.
