Traditionally, voting takes place "from sunrise to sunset" but times are usually rounded to the nearest "top of the hour" (e.g., 7 am to 8 pm). Individual precincts may prolong voting time at the judge's discretion, if there are still voters queueing up to vote. Voters identify themselves by their ID cards and are given the full number of ballot papers for the constituency plus a blank ballot paper and an empty envelope. Then they withdraw to a secluded cubicle equipped with a lectern, pen and waste basket, where they select the ballot paper of their choice, if any, and mark the candidate(s) of their choice, if any; they cast the sealed envelope with the ballot paper in the ballot box and are given their ID card back.
