The latest avatar of the Electronic Voting Machine is called ‘M3’ and the Election Commission is looking to ramp up its production ahead of the 2019 Lok Sabha polls.

EVMs were first used in 1998 so any improvement is welcome.

On technology improvements in the M3:

The M3 comes with digital verification system coded into each machine which is necessary to establish contact between its two component units. This makes it absolutely tamper proof.

Numerous reports of EVM hacks have surfaced over the years, even leading the Supreme Court to order the Voter Verifier Paper Trail (VVPT) system in 2013.

5.5 lakh new M3 EVMs have been ordered already at a cost of Rs. 3,000 crore, to replace an estimated 9 lakh M1 machines. Approval is awaited on adding a third PSU to ramp up manufacturing:

Central Electronics Ltd in Ghaziabad could soon join Bharat Electronics Ltd (BEL) and Electronics Corporation of India, sources in the EC confirmed.
