Section 8-304. Voters; signature identification

1. A person before being
  allowed to vote shall be required, except as provided in  this  chapter,
  to  sign  his  name  on  the back of his registration poll record on the
  first line reserved for his signature at the time of election  which  is
  not  filled  with  a  previous signature, or on the line of the computer
  generated  registration  list  reserved  for  his  signature.  The   two
  inspectors  in  charge  shall satisfy themselves by a comparison of this
  signature with his registration  signature  and  by  comparison  of  his
  appearance with the descriptive material on the face of the registration
  poll  record  that he is the person registered. If they are so satisfied
  they shall enter the other information required for the election on  the
  same  line  with the voter's latest signature, shall sign their names or
  initials in the spaces provided therefor, and shall permit the applicant
  to vote. Any inspector or inspectors not satisfied shall  challenge  the
  applicant forthwith.
    2.  If  a  person  who alleges his inability to sign his name presents
  himself to vote, the board of  inspectors  shall  permit  him  to  vote,
  unless  challenged  on  other grounds, provided he had been permitted to
  register without signing his name.  The  board  shall  enter  the  words
  "Unable  to  Sign" in the space on his registration poll record reserved
  for his signature or on the line of the computer generated  registration
  list  reserved  for  his  signature  at  such election. If his signature
  appears upon his registration record  or  upon  the  computer  generated
  registration  list  the board shall challenge him forthwith, except that
  if such a person claims that he is unable to sign his name by reason  of
  a  physical  disability  incurred  since his registration, the board, if
  convinced of the existence of such disability, shall permit him to vote,
  shall enter the words "Unable to Sign" and a brief description  of  such
  disability  in the space reserved for his signature at such election. At
  each subsequent election, if such disability still exists, he  shall  be
  entitled  to  vote without signing his name and the board of inspectors,
  without further notation, shall enter the words "Unable to Sign" in  the
  space reserved for his signature at such election.
    3.  The  voter's  signature  made  by  him  upon  registration and his
  signature made at subsequent elections shall  be  effectively  concealed
  from  the  voter  by  a blotter or piece of opaque paper until after the
  voter shall have completed his signature.
    4. In any case where a person who has heretofore voted has placed  his
  voting  signature  on  the  back  of his registration poll record on the
  first or any succeeding line or  lines  at  the  time  or  times  of  an
  election,  instead  of on the last line of the space thereon required to
  be reserved for such voting signatures and on  any  lines  next  running
  upward  therefrom,  the  inspectors  of  election  shall obliterate such
  misplaced signature or signatures, initial the obliteration and  require
  such  voter  to  sign  his  name  again  in  the  correct  place on such
  registration poll record.
    5. Any person who has heretofore  registered  and  who  at  such  time
  placed his or her registration signature on the back of the registration
  poll record otherwise than in the space required to be provided therefor
  at the bottom of such poll record, shall, before being permitted to vote
  at  any  election thereafter, subscribe a new registration signature for
  himself on the last line at the bottom of such poll record, and, at  the
  same  time,  if  the  inspectors  of  election  are  satisfied  that the
  signatures were  made  by  the  same  person,  obliterate  his  original
  registration  signature  placed  elsewhere  than  on  the bottom of such
  record. Such obliterations may be made by crossing out the signature  so
  as  to  completely  efface  the same or by affixing thereover a piece of

  gummed tape of a size sufficient only to cover such signature and  of  a
  type adequate to fully conceal the same.
