PCI PIN Security

Overview

The PCI PIN Security Standard addresses PIN processing across acquiring and payment environments, including key creation, conveyance, loading, use, administration, and secure equipment. It applies to relevant online and offline PIN transaction processes.

PIN security depends on cryptographic separation, controlled key components, dual control, protected devices, secure translation, and auditable ceremonies. PCI PIN requirements differ from ordinary password management and from broader PCI DSS account-data controls.

Organizations should determine their PIN role, use current standards and approved equipment, restrict personnel, document key ceremonies, and validate service providers. Compromise response must address keys, devices, affected transactions, and required payment-network notification. Personnel access to key components and ceremonies should be independently reviewed.

Dependencies can weaken PCI PIN Security even when the primary component behaves correctly.

An auditable record of PCI PIN Security should link checkout, authentication, authorization, capture, transfer, delivery, refund, dispute, and settlement events to the governing policy or model version, source evidence, decision, approver, exception, action, and final outcome.

PCI PIN Security defines requirements for securely managing, processing, transmitting, and protecting payment-card PIN data and associated cryptographic keys. PIN protection requires specialized cryptographic equipment, key lifecycle controls, dual control, documented ceremonies, and role-specific validation beyond general PCI DSS.

A production treatment of PCI PIN Security should test PCI PIN Security defines requirements for securely managing, processing, transmitting, and protecting payment-card PIN data and associated cryptographic keys within the relevant asset, decision, or service state. The PCI PIN Security context record for processing, and transmitting should preserve source data, configuration or policy version, responsible actor, exception, and outcome. Review of PCI PIN Security should determine whether safeguards addressing processing, and transmitting changed exposure in practice, not merely whether a document or setting existed.
