PCI PIN Security defines requirements for the secure management, processing and transmission of PINs and the cryptographic keys that protect them across the card-acquiring ecosystem. PCI P2PE (Point-to-Point Encryption) validates solutions that encrypt account data from the point of interaction to a secure decryption environment.
Who it applies to
- Acquiring banks and payment processors.
- ATM operators and networks.
- Providers of PIN-processing services and PIN-entry devices.
- P2PE solution providers and their component providers.
PCI PIN control areas
| Area | Requirement |
|---|---|
| PIN processing | Secure handling of PINs across the transaction lifecycle; never in clear outside a secure device |
| Key management | Secure generation, distribution, loading, storage, use and destruction of cryptographic keys |
| Secure cryptographic devices | Use of approved HSMs and PIN-entry devices (PEDs/POI) |
| Key-block requirements | Migration to secure key-block formats for protecting keys |
PCI P2PE
- Encrypts account data at the point of interaction (POI) so merchants never handle clear card data.
- Uses validated solutions listed by the PCI SSC, with defined domains (encryption, decryption, key management, POI management).
- Significantly reduces a merchant’s PCI DSS scope (SAQ P2PE).
PCI PIN vs PCI DSS
| PCI DSS | PCI PIN | |
|---|---|---|
| Protects | Cardholder data broadly | PINs and the keys that protect them |
| Applies to | Merchants and service providers | Acquirers, processors, ATM/PIN ecosystems |
How CyberSigma helps
As a PCI QSA-authorised firm, CyberSigma assesses PIN-security and key-management environments and advises on P2PE adoption to secure PINs and reduce PCI DSS scope.
Frequently asked questions
How is PCI PIN different from PCI DSS?
PCI DSS protects cardholder data broadly; PCI PIN focuses specifically on the secure management of PINs and the cryptographic keys that protect them across the acquiring chain.
What is PCI P2PE?
A standard for solutions that encrypt account data at the point of interaction so that merchants never handle clear card data — significantly reducing PCI DSS scope.
