Most voters will be required to show a photo ID to receive their ballot at the polls, but there are a few exceptions for confidential voters and voters with religious objections to being photographed. These two types of voters have IDs without photographs.
With the same exceptions, people who vote by absentee ballot at the clerk's office will have to show a photo ID.
Most people who vote absentee by mail will have to provide a photocopy of their photo ID. Exceptions are military and permenant overseas voters. Also exempt are permanent absentee voters who are "indefinitely confined" to their homes due to age, infirmity, disability or illness. For these voters, the witness signature on the absentee certificate serves as proof of their identity.
