PCI PIN Services

PIN security stands at the heart of many card present processing systems. Strong cryptographic methods and systems are used to securely capture and process PIN data worldwide.


Throughout the processing of online and offline payment card transactions at ATMs and POS terminals, the management, processing and transmission of personal identification number (PIN) data must meet certain security requirements as explicitly instructed by PCI. This particular set of requirements of PCI especially targets the acquiring institutions and agents which are in-charge of PIN transaction processing.

As mandated, acquirers must keep a summary listing of the cryptographic keys used for the acquiring and processing of PIN data including keys used by POI devices, HSMs, etc. UL performs physical, logical as well as IP protocol and secure data encryption assessments of these devices. We strive to offer local support to our customers when possible, and we have several evaluation and technical support facilities around the world.
