ICSF supports these algorithms for generating and verifying personal identification numbers:

• IBM 3624 institution-assigned PIN
• IBM 3624 customer-selected PIN (through a PIN offset)
• IBM German Bank Pool PIN (verify through an institution key)
• IBM German Bank Pool PIN (verify through a pool key and a PIN offset). This algorithm is supported when the service using the PIN is processed on the Cryptographic Coprocessor Feature. Restriction: This algorithm is not supported on a z990, z890, z9 EC or z9 BC.
• VISA PIN through a VISA PIN validation value
• Interbank PIN

The algorithms are discussed in detail in PIN Formats and Algorithms.
