evidence: EVMs or electronic voting machines provide the voter with a button for each choice which is connected by a cable to an electronic ballot box. An EVM consists of two units--control unit and balloting unit--and these two are connected by a five-meter cable. When a voter presses a button against the candidate he/she wishes to vote for, the machine locks itself. [...] Advantage of EVM - EVMs reduce the time in casting votes - EVMs also reduce the time taken to count votes and declare results - Claims were made earlier that the systems could be tampered with and the security could be breached - EVMs save paper - These machines are powered by batteries and do not rely on electricity which ensures uninterrupted voting - EVMs can accommodate 64 candidates in a single constituency - Votes can be stored for up to 10 years - The program of EVMs cannot be changed and have a sealed security chip, therefore votes cannot be rigged without damaging the program. This prevents fraud.
