Greenphire ClinCard: Study Participant Payment

ClinCard is a reloadable prepaid debit card available as an alternative to study teams to provide a simple, secure, and fast way to disburse study participant payments and reimbursements. The ClinCard portal helps automate, track, and report on incentive payments across all studies, and stay compliant with tax law and HIPAA regulation. 


Frequently Asked Questions:

What is the ClinCard?

The ClinCard is a reloadable debit card managed by a company called Greenphire. The card can be provided as a physical card or a virtual card. When a visit is completed, funds will be approved and loaded onto your card, usually within two days.  You may use this card at any store that accepts credit cards or you can use a bank machine to remove cash (there may be fees drawn against the balance of the card for cash withdrawals).

 What information is needed to set up the ClinCard?

The study team will give Greenphire your name, address, email address, telephone number , date of birth and Social Security number as part of the payment system. Your Social Security number is not required if you are only being reimbursed for study-related expenses (such as parking or food).  Greenphire will only use this information to make sure you get paid.  Greenphire will not use your information for any other purposes, and they will not give or sell your information to any other company.

How does Greenphire protect my personal information?

Greenphire has administrative, physical, and technical safeguards to protect your personal information.  Your personal information will be used and disclosed only to support the described payment activities.  Your information will be retained only as long as necessary to provide study payment to you and for compliance with applicable laws.

Will my choice about use of the ClinCard impact my participation in the study?

No. You can still receive your study payment without choosing to participate in the ClinCard program. Your decision will not impact your ability to be in the study.  You can discuss what you would need to do to be paid by an alternate payment option with the study team.

If I sign up to be paid through the ClinCard can I change my mind?

If you no longer want to be paid through the ClinCard you can notify the study staff and once you make the decision, your personal information will not be further shared with Greenphire, however, this may not affect processing that occurred before you changed your mind.

What if I am being paid to participate in the study and I do not have or cannot remember my Social Security number?

If you are being paid to participate in the study and you do not have or cannot provide a social security number, an automatic 30% tax withholding will apply.  This will mean that you will be paid 70% of what is described in the consent form.  If you have questions about this, please talk to the study staff.
