What if a merchant refuses to cooperate?
PCI is not, in itself, a law. The standard was created by the major card brands such as Visa, MasterCard, Discover, AMEX, and JCB. At their acquirers/service providers discretion, merchants that do not comply with PCI DSS may be subject to fines, card replacement costs, costly forensic audits, brand damage, etc., should a breach event occur. For a little upfront effort and cost to comply with PCI, you greatly help reduce your risk from facing these extremely unpleasant and costly consequences.
