E-voting systems will be beneficial to all people who are involved in elections. For example, administrators can improve operation of tasks for elections, and voters can vote in an election anytime and anywhere. In addition, ideal e-voting systems have transparency, completeness (only voters have the right to vote and their votes are correctly counted), and verifiability (voters can check that their vote is correctly counted), and therefore it is better than existing voting system. Digital voting is the use of electronic devices, such as voting machines or an internet browser, to cast votes. These are sometimes referred to as e-voting whenvoting using a machine in a polling station, and e-voting when using a web browser.
