N.J. Stat. § 19:31-3.3
The commissioner may eliminate the use of the duplicate permanent registration binders and may authorize and direct the use at the polls in place of such a binder, as a signature copy register for the purposes of this Title and Title 40 of the Revised Statutes, of a polling record which identifies on each page the election at which the record is used, which indicates for each registrant the name, address, and date of birth of the registrant and identifies the municipality and the particular election district therein from which the person is registered, and which includes adjacent to the registrant's name and address an imprint of the digitalized image of the registrant's signature and sufficient space, immediately to the left or right of that imprint, for the registrant to sign the record, which imprint and signature shall be used as the signature comparison record as prescribed by this Title. The polling record shall also include for each registrant the registrant's date of birth, an indication of whether the registrant has applied for a mail-in ballot in that election, and a place to indicate whether the registrant has provided identification pursuant to R.S. 19:15-17, if such identification is required. The polling record shall also include for each registrant sufficient space for the notation of remarks as provided by R.S. 19:15-23 and for the recording of any challenge and the determination thereof by the district board as provided by R.S. 19:15-24, or by other elections officials charged with the same duties as the district board in connection with the conduct of an election. In the case of a primary election, the polling record shall also indicate for each registrant the political party, if any, of which the registrant is a member for the purpose of voting at that primary election.
Polling records for each election shall be prepared by the commissioner of registration not later than the 10th day preceding the election. At each election, the delivery of the polling records to the municipal clerk and to the district boards or other elections officials charged with the same duties as the district board in connection with the conduct of an election, and the return of those records by the district boards or such other elections officials to the commissioner of registration, shall be made in the manner prescribed by the commissioner.
The commissioner of registration shall retain the polling records for any election for a period of not less than six years following that election.
