This system determines whether the person who is to participate in voting is an eligible voter and whether he/she has already cast a vote based on cross-checking with the integrated voters' list. Voter identification is carried out by scanning a signature/fingerprint or an ID card. A voting right card is issued to a voter who proves to be a duly authorized eligible voter. This card contains only basic information on the voter's electoral district. After voting, said information is deleted. When a voting right card is issued to an eligible voter and his/her signature is affixed to the card, the integrated voters' list cross-checking system serves to prevent double voting by automatically recording such fact in the integrated voters' list.
