1.7 Appendix A

Payment Card Merchant Services and Payment Card Industry Data Security Standards (PCI DSS)


Credit and debit card payments are generally one of the most efficient and convenient ways to process payments for goods and services. A university School/College/Division unit that accepts payment cards from internal and/or external customers is a merchant.

As with any business transaction, there are responsibilities and risks that a merchant and their School/College/Division assumes when they agree to process customer credit and debit card payments. These responsibilities include the need to comply with the university's contractual and legal requirements with the payment card companies.  One of these contractual and legal requirements is the need to comply with the Payment Card Industry Data Security Standards (PCI DSS).  The purpose of the PCI DSS is to protect card holder data. PCI DSS provides a specific framework for creating, maintaining and protecting a secure payment card environment for customers using credit and debit cards.

The following web-link provides greater details about PCI DSS: https://www.pcisecuritystandards.org/security_standards/pci_dss.shtml


The Cashiers Office and Cash Management, in collaboration with Computing & Information Technology (C&IT) are responsible for overseeing the PCI DSS process. The Cashier's Office is responsible for approving all new requests to accept credit card payments by proposed merchants and termination of existing merchants. C&IT is primarily responsible for assessments of electronic transmission and storage of card payment data and serving as the liaison with the network scanning service provider used by the university. If the Cashier's Office determines that a stand-alone merchant terminal is required, it will request that Cash Management establish the merchant account.  Cash Management is responsible for assigning new merchant account numbers for stand-alone terminals, administration of the overall annual PCI Self-Assessment Questionnaire and Attestation of Compliance process and serving as the primary liaison with university's banks regarding compliance with credit card company agreements, including PCI DSS related matters.

University Requirements

  1. Protect Cardholder data.

  2. Must not store customer card information (physical or electronic).

  3. Within thirty days after the calendar year end, complete and submit an annual PCI DSS security self assessment questionnaire and take any necessary corrective action(s) to comply with PCI requirements along with any related costs associated with this responsibility.

  4. Take immediate corrective action to resolve any issues identified by PCI network scans.

  5. Notify the Cashier's Office in a timely manner of any changes of staff that have been authorized to process card payments, or that have been assigned responsibilities for the systems or business procedures used for processing the card payments.

  6. Assume responsibility for ensuring that any external vendor using a non-university system to process credit card transactions on their behalf adheres to the same PCI standards that the merchant must adhere to. Prior to implementation, all third party vendors that will access cardholder data must contractually agree to adhere to PCI DSS security requirements and to annually provide the university with a PCI DSS Certification of Compliance.  A Certification of Compliance must also be provided to the university Cashier prior to its approval of the initial third party vendor agreement.

  7. Refer all software purchases that execute electronic credit card payments or contracts to have an external third party vendor process card payments to the Cashiers Office for approval prior to submission to the Purchasing Department.  Any such software purchases must be certified as PCI DSS compliant prior to purchase.

Violations of Policy and Consequences

If an existing merchant does not comply with the aforementioned university and PCI DSS requirements, their ability to process card payments will be terminated. In addition, annually, not later than 30 days after the calendar year end, each merchant must submit a completed PCI DSS security self-assessment questionnaire and document along with any necessary corrective action taken in order to comply with PCI DSS requirements.   Each merchant must take the necessary action(s) to correct any issues identified by PCI network scans as soon as possible, but depending on the severity of the issue, no later than one month after receiving the initial scan results that identified the non-compliance issue.

Other Violations that could result in termination include:

  1. Frequent failures to comply with PCI DSS requirements.

  2. Frequent failures of PCI network scans.

  3. Failure of a School/College/Division using an external vendor for any aspect of processing credit card transactions to obtain an annual certification from that vendor which states that their card payment application complies with the PCI standards.

  4. Failure to properly report compromises of customer cardholder information in a timely manner.
