PIN Security Explained
Protecting PINs is mission-critical—one breach can dismantle trust and trigger costly fallout.
Hardware-Based Encryption
Ensures PINs are encrypted inside secure devices before leaving the terminal environment.
Secure Key Injection
Delivers cryptographic keys into devices via tightly controlled, auditable injection procedures.
Multi-Layer Controls
Applies layered protections across device lifecycle, network, and processing infrastructure.
PIN Environment Protection
From ATMs to POS devices, PIN environments must remain tamper-proof, encrypted, and verifiably secure across their entire lifecycle.
Terminal Key Injection
Cryptographic keys must be injected using secure, certified methods with strict access controls.
Device Tamper Detection
Devices must detect and respond to any unauthorized physical access attempts instantly.
Secure PIN Entry
PIN entry devices must obscure input and prevent interception through shielding or scrambling methods.
End-to-End Encryption
Encryption must persist from the point of entry to the secure decryption environment.
Core PIN Objectives
PCI PIN Security exists to ensure PIN data remains confidential, intact, and inaccessible across every phase of the transaction process.
