  registration. If a voter registration exemplar signature is not received
  from an applicant who submits a voter registration  or  pre-registration
  application  pursuant  to  this title and such signature exemplar is not
  otherwise available from the statewide voter registration database or  a
  state  or  local  agency,  the  local  board  of elections shall, absent
  another reason  to  reject  the  application,  proceed  to  register  or
  pre-register  and,  as applicable, enroll the applicant. Within ten days
  of such action, the board  of  elections  shall  send  a  standard  form
  promulgated  by  the  state board of elections to the voter whose record
  lacks an exemplar signature, requiring such voter to submit a  signature
  for  identification  purposes.  The  voter  shall submit to the board of
  elections a voter registration exemplar signature  by  any  one  of  the
  following  methods: in person, by mail with return postage paid provided
  by the board of elections, by electronic mail, or by  electronic  upload
  to  the  board  of  elections  through the electronic voter registration
  transmittal system. If such voter does not provide the required exemplar
  signature, when the voter appears to vote the voter shall be entitled to
  vote by affidavit ballot.
