An optical (CCD) scanner similar to the ones used in digital cameras is used for scanning. It is an array of light sensitive diodes .When they come in contact with light, they generate an electrical signal.An ADC system that converts electrical signal into digital. The scanner will also have a light source to illuminate the finger.

My desktop is bluetooth enabled..

It just cost around $4, a simple tool that now enables my system to be connected to any mobile devices which have Bluetooth enabled.
Before,I have to take the memory card out from the mobile phone, then insert it into a card reader and then connect through the USB port.Even after these steps the data transfer may be interrupted in the middle with giving some error message.Such annoying thing actually made me to take this wise decision.Now just like sending to a thumb drive, I can use the "send to" option to send to any connected device in the proximity, just like that.
