CHAPTER 1
Voter Verifiable Paper Audit Trail System
1.1 Introduction
Voter Verifiable Paper Audit Trail (VVPAT) system is a printer based accessory that interfaces
with the Control Unit (CU) and Ballot Unit (BU) in the conventional Electronic Voting Machine
(EVM). The VVPAT system prints the voter’s franchise on a thermal Printed Paper Slip and
gives visual indication and record of the cast vote to the voter and can be used for auditing
the EVM electronic counter at later stage.
The VVPAT system consists of following accessories.
1. VVPAT Unit
2. VVPAT Status Display Unit (VSDU)
(To display the status of VVPAT system to the polling staff and gives messages for
any action to be taken for VVPAT)
3. Interconnecting cable to CU
4. VVPAT Battery pack
5. Paper Roll
6. Carrying Case
1.2 Use of VVPAT for voter verification of vote
When the VVPAT system is used in combination with the EVM, it provides verification to the
voter by way of printing the cast vote on a thermal Printed Paper Slip. When the voter
presses the button on the Ballot Unit (BU) to vote for the candidate of his/her choice, the
VVPAT system prints a small Printed Paper Slip. The Printed Paper Slip (Fig 1.1) prints
amongst other information
(a) Serial number of the contesting candidate,
(b) Name of the candidate and
(c) Election symbol of the candidate party.
The Printed Paper Slip is visible to the voter for a period of 7 seconds after pressing of BU
key. The Printed Paper Slip gets automatically cut in the VVPAT unit and falls into the Printed
Paper Slips Compartment.
A sample photograph of VVPAT Printed Paper Slip is shown in Fig 1.1
