Final answer:
The PCI SSC (Payment Card Industry Security Standards Council) is responsible for developing and enforcing payment card security compliance programs.
Step-by-step explanation:
The entity responsible for developing and enforcing compliance programs related to payment card security is the PCI SSC (Payment Card Industry Security Standards Council). Issuers and acquirers are required to adhere to the standards set forth by the PCI SSC, but they do not develop these compliance programs themselves. The payment card brands, such as Visa and Mastercard, also enforce compliance by ensuring that merchants and service providers adhere to PCI standards, but the development of the standards is overseen by the PCI SSC.
