CU-Boulder students will take the first step toward automating many of their business transactions this spring when their pictures are taken for the new Buff OneCard, designed to provide one-stop shopping for administrative and some commercial transactions on and off campus. The Buff OneCard will become the new identification card for studentsÂ’ university business including access to dining halls, the Recreation Center, Wardenburg Health Center, Norlin Library and eventually to buildings or portions of buildings that now require a key to enter.
