Another proposal achieved more success; that of electoral cards. This system consists in this, that electoral lists, instead of being made up by the administrative authorities, are made up by the electors themselves. To this end there are given by the communes to their electors cards which consist of several coupons. The elector fills out his card and returns it to the municipality, which verifies and completes it. The cards are then sent to the seat of the electoral district and are numbered. Then the coupons are detached. Coupons Number 1 make up the electoral lists; coupons Number 2 make up a duplicate; coupons Number 3 are sent back to the electors. This last coupon is for the elector a proof that he is entered on the electoral rolls and establishes his identity and the number he bears on the roll, before the election board. It is his voting card. This system is a simplification, in the sense that it dispenses with the making of an alphabetical list and puts part of the work on the elector. But in spite of these advantages it has not been completely adopted. The electoral law _provides, that, the different districts before each election must prepare lists of its electors; and it leaves to them the choice of preparing this list either according to customary rule for electoral lists, or according to the procedure of electoral cards_. The elector is entered on the list of the district in which he lives, and it is there theoretically that he is supposed to vote. But there is an exception to this rule; if he is away from home on the day of election, either because of business reasons that compel his travelling at the time of election, or because of a necessary absence at some health resort, or because he has had to change his residence before election, he can demand an electoral certificate[29] which will permit him to vote in any electoral district of the Reich. This innovation has appeared to present little danger, for in the new electoral system a political party is never interested in getting more votes in one district than in another. Every elector is eligible as candidate for the Reichstag on the double condition that on the day of election he is twenty-five years old, and that he has been a naturalized German for at least a year. In addition to this he must be regularly placed on the list of candidates. It will be recalled that for the National Assembly every elector was eligible; one could thus be elected member at the age of twenty. Actually, however, the youngest elected was twenty-seven years old. The new law returned to the rule followed for the former Reichstag in fixing the minimum age at twenty-five.
