Polling card   The Population Registration Centre shall compile a polling card on each person entered in the voting register, which shall include: the information referred to in section 18, subsection 2(2), (5) and (6); the address of the enfranchised person which is in the Population Information System at 12 midnight 51 days prior to the polling day;  the information stating in which election and voting district or municipality the recipient of the card is entitled to vote; the information stating the polling day and the period of advance voting;  the contact information of the local register office which has been marked as the sender of the card and the municipal central election committee;  the information stating the register or the information system on which the information on the card is based;  instructions on how to use the card and the voting procedure. The polling card may also include, where applicable, the information referred to in section 18(2) and (3) in optically readable form.   The polling card shall be compiled so that it can be used as a covering letter in other forms of advance voting with the exception of at-home voting.   The Population Registration Centre shall see to it that the polling cards are sent at least 24 days prior to the polling day to the persons with a known address who have the right to vote. In European Parliamentary elections, however, the card shall not be sent to the persons who have been entered in the voting register in accordance with section 26(5) by the Population Registration Centre as ineligible to vote.   In the Presidential election, two polling cards shall be sent to the enfranchised persons, one for each round of the Presidential election.
