Students at Purdue University are already lining up to vote for the next U.S. president. This year, to make it easier for students, Purdue and Tippecanoe County have established a system that will accept Purdue student ID cards as proof of residence at the polls.

Workers will compare each student’s ID with the school’s database to confirm that the individual is a current student and old enough to vote. An Indiana driver’s license or U.S. passport will also, of course, be accepted as proof of residence.
