Approval from the Office of Treasury Operations (OTO) is required before any person, department, unit, entity, campus or Third Party Service Provider may accept Payment Cards as a method of payment on behalf of the University.

Approval from the OTO also is required prior to purchasing any software or hardware or engaging with and/or entering into any contract with Third Party Service Providers that may facilitate the acceptance of Payment Cards as a method of payment. The requisite Merchant Account must be established by the OTO. Only individuals and entities that can demonstrate compliance with the Payment Card Industry Data Security Standard (PCI DSS) as well as this standard will be granted a Merchant Account. 

The University has engaged in an exclusive strategic partnership to provide secure e-commerce solutions for accepting Payment Cards as a method of payment. Payment acceptance needs that cannot be met through this strategic partnership and require an alternative solution must be reviewed and approved on a case by case basis by the Senior Vice President and Assistant Treasurer via the OTO before engaging any alternative Third Party Service Providers and/or solutions. All Third Party Service Providers must demonstrate their PCI compliance prior to engaging with any University Merchant and must provide appropriate documentation at any time upon request.   Merchants approved to accept Payment Cards will be subject to annual review of compliance and must therefore implement secure processes, adhere to all applicable PCI DSS requirements published and maintained by the PCI Security Standards Council (see appendix A for an outline of the standards), and maintain best business practices as described in business and IT procedures associated with this standard.

Merchants that transact business using Payment Cards in a manner that deviates from this standard are subject to various financial penalties and sanctions.
