Bluetooth is a technology that does not require any wires. It allows you to exchange data with another person, that is close enough to you, it does this buy using short wavelength radio transmissions, which then mean only people that you want to send items to are the only people receiving it.
It was created in 1994, by Ericsson which is a telecoms vendor, it is generally used in phone these days, therefore most people that have a recent mobile phone, now have the power of bluetooth at there finger tips.
The benefits of Bluetooth is that you can send and receive items via a mobile device that has bluetooth with ease, also you can connect the phone to a hands-free device that you can talk to people with out having to answer your mobile device, therefore you can talk to someone with your bluetooth device with out having to take your phone out of your pocket.
However the draw backs to bluetooth is that when your are using the hands-free device you have to have your bluetooth on, therefore people can find your phone and then they can hack your phone and find out your details if you have them on your phone. Also with bluetooth you will be able to talk on your phone while driving, but even though it is hands free you can still be distracted, from concentrating on the road.
