TIVI Verifer uses a device’s camera when you ask it to capture information about the vote encoded in the QR-code by the voting application. The app uses this information to download the i-vote from the online system for the purpose of analysing the received vote. The analysis is performed within the device and the results are presented to you as the voter and authorised user of the device, providing you with an assurance that your vote was correctly cast by the voting application and received by the online voting platform.
