    Capacitive sensors use an array capacitor plates to image the fingerprint. Skin is conductive enough to provide a capacitive coupling with an individual capacitive element on the array. Ridges, being closer to the detector, have a higher capacitance and valleys have a lower capacitance. Some capacitive sensors apply a small voltage to the finger to enhance the signal and create better image contrast. Capacitive sensors can be sensitive to electrostatic discharge (shock) but they are insensitive

    Overview Arduino Pro A huge variety of microcontrollers already exist on the market. After comparing several types of boards, including ATMEL, INTEL and PIC based ones; an ATmega328 based ship was assigned for the implementation of our prototype: The Arduino Pro, which is cheaper in price and smaller in size than the other boards, and satisfies perfectly our needs. The Arduino Pro comes in both 3.3V/8MHz and 5V/16MHz versions. After benchmarking these two existing boards, the 5V/16MHz one was chosen

    being used in the real time environment i.e., in a closed loop operation. So many advancements in the MEMS technology make the MEMS production very effective, but still there are some drawbacks in its structure and in its performance, which pulls the system efficiency to down. Self and mutual inductions are the two major run time defects which affects the performances of the MEMS devices and increases its power consumption when there is a physical data link between two blocks. If the proper steps are
