An electronic referendum (sometimes called an e-referendum) is a way for people to vote on something over the internet. This means that people don't have to go to a physical voting booth or polling place; they can just go online and cast their vote. It's like getting a survey or taking a quiz online but instead of answering questions, you are deciding on a political issue or law. With an electronic referendum, the results are usually announced quickly, since there is no need to collect and count physical ballots.
