20,000 units of VVPAT (10,000 each from M/s BEL and M/s ECIL) costing about Rs. 38.01 crore. 28) Though initially the ECI was little reluctant in introducing “paper trail” by use of VVPAT, taking note of the advantage in the system as demonstrated by Dr. Subramanian Swamy, we issued several directions to the ECI . Pursuant to the same, the ECI contacted several expert bodies, technical advisers, etc. They also had various meetings with National and State level political parties, demonstrations were conducted at various places and finally after a thorough examination and full discussion, VVPAT was used successfully in all the 21 polling stations of 51-Noksen (ST) Assembly Constituency of Nagaland. The information furnished by the ECI, through the affidavit dated 01.10.2013, clearly shows that VVPAT system is a successful one. We have already highlighted that VVPAT is a system of printing paper trail when the voter casts his vote, in addition to the electronic record of the ballot, for the purpose of verification of his choice of candidate and also for manual counting of votes in case of dispute. 17 Page 17
