4. Uses of Bluetooth

A Bluetooth enabled phone will detect phones nearby and provide you with a list of usernames. You can then send a message, photograph or movie sitting on your phone to any of the usernames. They, of course, have to accept the offer but the rest of it is automatic.

Another common use of Bluetooth is 'hand-free' operation of mobiles in the car.

There are two ways to do this. Many modern cars let you 'pair' your phone to the car system. The car automatically 'reads' the mobile's details such as your contact list, so it is simple to make and receive a call.

Another way, is to wear a bluetooth headset that senses your mobile nearby. This allows you to talk using the mobile, but most importantly, keeping your hands on the steering wheel!

There are also Bluetooth enabled printers and digital cameras.
