Merchant Card Services and E-commerce

All Saint Louis University merchant accounts must be authorized by Treasury and Investments and the SLU PCI Compliance Committee. The department must demonstrate a valid business need for a merchant account and demonstrate certain business operation and financial management criteria.

Saint Louis University accepts Visa, MasterCard, Discover and American Express via e-commerce solutions, third-party gateways, standard terminals and wireless terminals. Please review the Merchant Card Policy (PDF) for more information on credit card processing.

A merchant account is required to accept receipts from credit and debit card transactions. All merchant accounts are created through the University's merchant services provider contract with Fiserv. To establish a merchant account, or make changes to an existing merchant account, complete the Merchant Services Account Request/Maintenance form (PDF).

Credit Card Training

Only authorized and properly trained individuals can process credit card transactions and access systems or reports containing credit or debit card data. Employees with access to cardholder data or who are involved in credit card processing must complete credit card security training upon hire and annually.

Employees will be notified of their annual training via email. Employees who do not complete the credit card training within 30 days of the initial notification will have all credit card processing privileges removed, and the respective dean or vice president will be notified.

Contractors, volunteers and other individuals who are not University employees and who plan to accept or process credit or debit cards on behalf of Saint Louis University must also be trained prior to taking on their credit and debit card handling duties and annually after that. It's the responsibility of the merchant manager to notify Treasury and Investments at of any non-employee processing or handling credit or debit card data.

If you have requested to borrow a special events credit card terminal, email to be added to the PCI training. This training must be completed before you can begin processing credit card transactions on behalf of the University.

Departments processing charges by bank credit card must do so electronically using a terminal and printer or e-commerce product approved by the Treasurer's Office.

SLU PCI Committee

Saint Louis University accepts credit card payments as a convenience to its customers and is committed to protecting and preserving the privacy and security of payment card data collected and processed to conduct University business operations. Saint Louis University has a fiduciary responsibility to patients, students, donors, customers and payment card processors to comply with the Payment Card Industry Data Security Standards (PCI DSS) when handling payment card transactions.

The PCI Compliance Committee was established to govern PCI DSS and oversee merchant card processing compliance for the University. The committee consists of members from Information Technology Services, Treasury and Investments and representatives from various University merchants.

All University departments that handle, store, process or transmit cardholder data, including any Saint Louis University employee, contractor or agent who, in the course of doing business on behalf of the University, is involved in the acceptance of credit cards and e-commerce payments for the University, must comply with PCI DSS.

The PCI DSS are technical and operational requirements set by the PCI Security Standards Council (PCI SSC) to protect cardholder data. The council is responsible for managing the security standards, while the payment card brands enforce compliance. These standards include controls for handling and restricting credit card information, computer and internet security, as well as the reporting of a credit card information breach.

Loaner Credit Card Terminal

The Treasurer's Office maintains five loaner terminals, which are available to departments for special one-time events. Departments requesting the use of a terminal must read the Special Events Loaner Credit Card Terminal Policy and complete the Special Events Loaner Credit Card Terminal Request Form.
