Multiple enrollments for one voter at a different location is the major problem in electoral database management. One of the main reasons behind this is that the voters frequently travel and change their residences and get themselves enrolled in new places without getting their previous enrollment. It makes a problem as one person can have more than one voting right and also cause chances for bogus voting. The linkage of the Adhar card with the voter ID can help solve the multiple enrollment issue effectively.
