Answer:
Absentee voting.
Explanation:
An absentee ballot is a vote cast by someone who is unable or unwilling to attend the official polling station to which the voter is normally allocated. Once filled, the ballot must be sent to a local election office by mail.
Absentee body can interfere with voter identification laws in the sense that it is not possible to know if the citizen in question is actually voting when submitting their ballot, since their physical presence is disregarded and anyone could secretly take their place when filling the ballot.
