VVPAT stands for Voter-Verifiable Paper Audit Trail. It is a system that is used to provide a physical record of the votes cast in an electronic voting machine (EVM). The VVPAT system is designed to increase the transparency and integrity of the voting process by allowing voters to verify that their vote has been recorded correctly and to detect any potential errors or fraud.
A VVPAT system is made up of a printer that is connected to an EVM. When a voter casts their vote, the EVM records the vote electronically and the VVPAT printer prints a paper record of the vote. The voter can then verify that the vote has been recorded correctly by comparing the paper record to the electronic record.
VVPAT systems are used in many countries around the world, including India, Brazil, and the Philippines. In India, VVPATs have been used in all general and state assembly elections since 2019. The VVPAT system helps to increase voter confidence in the electoral process and also helps to detect any potential errors or fraud.
The VVPAT system is also used to verify the results of the election. A random sample of VVPATs is manually counted and compared to the electronic results to ensure that the electronic results are accurate.
