Bluetooth wirelessly connects (or ‘pairs’) devices together over short distances. It’s commonly found in phones, cars, computers, fitness trackers, gaming consoles and controllers, headphones, tablets and TVs.
Bluetooth is used to pair wireless devices like headphones, keyboards, or a mouse to phones or computers. It’s also what enables you to make and take hands-free calls while driving.
Are there any risks in using Bluetooth?
Because it uses radio waves, Bluetooth is susceptible to eavesdropping and remote access. Connecting over Bluetooth can expose private information, allow a person to send you viruses, or even enable a person to control the Bluetooth device.
Although it sounds like something out of a spy story, it’s not unheard of for cars to be hacked through the car’s Bluetooth connectivity. If another person pairs your phone with their car, they can receive calls intended for you if they are close by (generally within 10 metres).
