One of the most important items you will need at Carnegie Mellon is your official identification card. Your ID Card identifies you as a member of the CMU community and will be part of your everyday life on campus.
Your ID Card can be used to access many campus facilities and services, including your residence hall, recreation facilties, for public printing and copying, and more! View a complete list of facilities and services.
One beneficial feature of your ID Card is Plaid Ca$h. Plaid Ca$h is a prepaid, stored-value/debit account that is accessible via your ID Card. It is a convenient, cashless way to pay on and off campus. You can use Plaid Ca$h for textbooks, school supplies, restaurant meals, take-out and more. View a list of participating businesses.
