The coastal state is the first in the country to adopt Poll Monitoring System in the assembly elections. Under the system, photographs and fingerprints of all voters will be captured on computers.
The voting will begin from 7 AM and would be held at 1612 polling booths with 10,644 poll personnel on duty.
Joint Chief Electoral Officer Narayan Navti said all measures have been taken to ensure a fair and free election in the state.
He said a total of 3526 local policemen along with companies of para military forces have been deployed to prevent any lawlessness.
The list of sensitive and hyper sensitive constituencies have already been drawn up. The areas of St Cruz and Chimbel, adjoining Panaji city have been declared as troubled, where police presence is thick.
The Election Commission has also identified 180 critical and vulnerable polling booths in the state, which will be kept under special supervision of micro observers.
While the actual fight is set to be between Congress-NCP and BJP-MGP, the introduction of Trinamool might spring political surprises in many constituencies.
The 2012 election might come out with some surprising verdicts as the Congress is facing internal rift. While several senior leaders from Congress party are upset over ticket distribution and are contesting as independents, BJP in alliance with MGP might gain.
Leader of opposition Manohar Parrikar is seeking re-election from Panaji constituency and Chief Minister Digamber Kamat from Margao.
