The PCI Data Security Standards were established by Visa, MasterCard, and other credit card brands to protect consumer card data and ensure that all entities involved in processing card transactions, including merchants, banks, and processors, maintain security protocols. The PCI Security Standards Council developed and maintains the PCI Data Security Standard that businesses must comply with to protect cardholder data from being compromised. NPC, a merchant acquirer and processor, strives to be compliant with these PCI DSS standards.
