The Independent National Electoral Commission,INEC says card readers will shut down automatically by 10:00PM on the day of elections.

INEC Chairman, Mahmood Yakubu, disclosed this on Wednesday in Abuja during a briefing on the progress made by the commission following the postponement of the general elections.
He said the card readers are configured to specific polling units and only open for use at 8:00AM on the Election Day; they will automatically shut down by 10:00PM in order to forestall any illegal use of the card readers before the appointed time for elections.
Professor Yakubu explained that the card readers were introduced in 2015 to facilitate the accreditation of the electorate using the Permanent Voter Cards,PVC.
Following the postponement of the elections, he said they were reconfigured to the new date of February 23, to make them impossible to be used for ulterior motives.
