Title 21, Chapter 2, Section 431
(a) At every primary and election, each elector who desires to vote
shall first execute a voter's certificate and hand the same to the
poll officer in charge of the electors list. When an elector has
been found entitled to vote, the poll officer who examined his or
her voter's certificate shall sign his or her name or initials on
the voter's certificate and shall, if the voter's signature is not
readily legible, print such voter's name under his or her signature.
As each elector is found to be qualified and votes, the poll
officers shall check off the elector's name on the electors list and
shall enter the number of the stub of the ballot issued to him or
her, or his or her number in the order of admission to the voting
machines, on the voter's certificate of such elector. As each
elector votes, his or her name in the order of voting shall be
recorded in the numbered list of voters provided for that purpose.
(b) If any elector was unable to sign his or her name at the time of
registration or if, having been able to sign his or her name when
registered, he or she subsequently shall have become, through
physical disability, unable to sign his or her name when he or she
applies to vote, he or she shall establish his or her identity to
the satisfaction of the poll officers; and in such case he or she
shall not be required to sign a voter's certificate, but a
certificate shall be prepared for him or her by a poll officer, upon
which the facts as to such disability shall be noted and attested by
the signature of such poll officer.
(c) Except as provided in Code Sections 21-2-218 and 21-2-386, no person shall vote at any primary or election at any polling place outside the precinct in which such person resides, nor shall such person vote in the precinct in which such person resides unless such person has been registered as an elector and such person's name appears on the electors list of such precinct.
