ID Card & Plaid Ca$h

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 Carnegie Mellon community. Your ID Card will be part of your everyday
life on campus and is used to access the following: •University Housing Residence
Halls •Computing Services & Computer Clusters/Labs •University Libraries •Local
Port Authority Transit (bus, incline, etc.) •Dining Services Meal Plans •Computer
Store •University Center Retail Shops •Athletic Facilities

If you completed the online photo submission process before arriving on
campus, your ID Card will be ready for pickup when you check-in
to your campus housing facility. If you have not yet submitted a photo, you may:

  • Go to to submit one online, or
  • Visit ID Card Services in The HUB, located in the lower level of Warner Hall to have your photo taken. You will need to check in at your campus housing facility FIRST.

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$h for textbooks, school supplies, and food. Some of the area's
most popular businesses accept Plaid Ca$h. You can use it to pay for
restaurant take-out, delivery and more. A list of participating
businesses can be found at

Your Plaid Ca$h account is open for deposits as soon as you are enrolled at the
university. You can deposit funds via SIO; and, if
your parents know your Andrew ID and your ID Card number, they may also use a Visa or

MasterCard to deposit funds online at Your ID card number
can also be found on your SIO account before you receive your card.
