Voters will have to generate a temporary QR code in the app and open it in front of polling station members, who will check it with the reader, a process that will take longer than checking a physical card. The code carries data signed by the National Police, and the reader confirms that it is authentic and current. Election boards will pass the decision to the more than 60,000 polling stations. MiDGT, the app that holds driver’s licenses, remains barred at the polls.
