PCI DSS applies to any entity that stores, processes, or transmits cardholder data, the Payment Application Data Security Standard (PA-DSS) applies to payment applications that store, process, or transmit cardholder data as part of authorization or settlement, and the PIN Transaction Security (PTS) POI requirements apply to ATMs and unattended payment terminals. That being said, while the Payment Card Industry Security Standards Council (PCI SSC) manages the payment standards and related processes, each payment brand is responsible for their own compliance programs, including such features as who must comply, due dates, fines, etc. To determine whether ATMs must validate PCI DSS, PA-DSS, or PTS compliance, please contact the payment directly.
