At the time of voting, the option of the voter is taken along with the finger print.
 The finger print taken by the scanner is sent to the pc through an in-built A/D converter. The processed image is transferred to hard disk. The option entered by the voter is   transferred to chip through DEMUX and is stored in the memory. If the transferred image is matched with any of the records in the data base, then the interrupt is given by the HARD DISK to pc. Then the option is considered in the count.
