The Election Commission will on Saturday hold a demonstration on the working of EVMs and VVPATs to allay fears that these can be tampered with in favour of a particular candidate or party.
It will also announce dates for a EVM-hacking challenge in the wake of opposition concerns over the reliability of EVMs.
The poll panel had announced after an all-party meeting on May 12 that it will hold the challenge to let opposition political parties prove their contention that the Electronic Voting Machines used in the February-March assembly elections were, or could be, tampered with.
It had also announced that all future elections will be held using VVPAT or Voter-verifiable paper audit trail.
A VVPAT slip allows a voter to verify if his vote has been rightly recorded by the EVM.
