ANSI X9.8 PIN - Allow modification of PAN

In order to enable the ANSI X9.8 PIN - Allow modification of PAN access control point, the ANSI X9.8 PIN - Enforce PIN block restrictions must also be enabled.

The ANSI X9.8 PIN - Allow modification of PAN access control point cannot be enabled by itself.

When the ANSI X9.8 PIN - Allow modification of PAN access control point is enabled, the input PAN and output PAN parameters will be tested in the Encrypted PIN Translate and Secure Messaging for PINs verbs. The input PAN will be compared to the portions of the PAN that are recoverable from the decrypted PIN block. If the PANs are the same, the account number will be changed in the output PIN block.
