Credit & Debit Cards-The HUB - Carnegie Mellon University

Credit & Debit Cards

The university now accepts both credit and debit card payments online through Education Computer Systems, Incorporated (ECSI).  Payments made through the ECSI website are subject to a non-refundable convenience fee.

Payments will appear on your credit card and bank statements with a description of “ECSI, LLP” or “ECSI”. Convenience fees may be reflected as a separate line depending on your card type.

For students making a debit card payment from a U.S. checking or savings accounts, CMU suggests that you instead enroll in Online Banking through Student Information Online (SIO).  Online Banking provides similar functionality to a debit card payment, but free of charge.


Go to the ECSI website to begin the payment process.  An Andrew User ID is required when paying via credit card. Your Andrew User ID is the prefix of your Carnegie Mellon email address. For example, brianhi is the Andrew User ID for
