Payments to research subjects should be made via one of the mechanisms listed below. Investigators and coordinators should not pay subjects with cash or prepay out-of-pocket. Payments made by investigators to subjects that do not adhere to university policies and practices will not be reimbursed.

The Prepaid One-time Card is a debit card issued by Swift Prepaid Solutions, Inc., to facilitate a single payment to individuals who participate in university clinical trials, research studies or incentive programs. More information can be found on the Prepaid One-time Card page. (USC NetID Log-In may be required to view this page.)

The Prepaid Recurring ClinCard (ClinCard) is a reloadable debit card issued by Greenphire, Inc., to facilitate recurring payments to participants of university clinical trials, research studies or incentive programs. More information can be found on the Prepaid Recurring ClinCard page. (USC NetID Log-In may be required to view this page.) Please note that as of January, 2017, the Keck School of Medicine is still sponsoring ClinCard fees (both card fee and load fee), but this sponsorship is subject to termination at any time and without notice. Please budget accordingly.
