Why is a voter ID card useful in elections?

Correct answer: To prove the voter's identity

Direct answer: A voter ID card is useful for proving or verifying the identity of the voter. At the polling station, officials need to check that the person present corresponds to an eligible entry in the electoral record. This helps reduce impersonation and bogus voting, although identity verification works within the complete election procedure and does not by itself guarantee every aspect of fairness. Option A is correct because the card provides identifying details that help confirm the voter. Option B is wrong because a voter ID card is not a statement of a candidate’s income. Option C is wrong because election results are declared after counting by the authorised election machinery, not by an identity card. Option D is wrong because the card is not a campaign-finance tool and does not increase campaign spending. The deeper idea is that accurate voter identification protects the principle of one eligible person, one vote. Memory cue: “ID checks the voter, not the candidate or result.”
