Election Commission will soon call an all party meeting to assure them that electronic voting machines (EVMs) are tamper-proof and secured. This was stated by the Chief Election Commissioner Nasim Zaidi in Chandigarh yesterday. He said, the Commission intends to use Voter-Verified Paper Audit Trail (VVPAT) in all coming elections to bring in more transparency and boosting the confidence of people in the electoral process. He was responding to questions about allegations levelled by various political parties against EVMs. Recently sixteen opposition parties had urged the commission to revert to ballot system.<br/> <br/>Mr. Zaidi said that the EC is planning to hold a challenge for which time frame is being worked out. The electoral body is planning to throw an open challenge, asking anyone to try hacking its EVMs to dispel doubts of any misuse.<br/> <br/>The CEC also said that the EC had placed an order for the supply of VVPAT machines for use in elections. He said by September next year around 15 lakh VVPAT machines will be ready.<br/> <br/>Mr. Zaidi added that India will "perhaps" be the first country where VVPAT will be used 100 per cent at all the poling stations. It will boost voters' confidence and will bring more transparency in the election process.
