Encrypted PIN Translate verb

Edit online

This verb extracts the customer-entered PIN from the input PIN block.

It extracts the PIN from the input PIN block according to the following rules:
  • If the input PIN block format is ANSI X9.8, ISO format 0, VISA format 1, VISA format 4, ECI format 1, ISO format 1, ISO format 2, ISO format 3, ISO format 4, VISA format 2, IBM® Encrypting PINPAD format, or ECI format 3 and, if the specified PIN length is less than 4, the verb sets a reason code to reject the operation. If the specified PIN length is greater than 12, the operation proceeds to normal completion with unpredictable contents in the output PIN block. Otherwise, the verb extracts the PIN according to the specified length.
  • If the input PIN block format is VISA format 3, the specified delimiter (padding) determines the PIN length. The search starts at the leftmost digit in the PIN block. If the input PIN block format is 3624, the specification of a PIN extraction method for the 3624 is supported through rule_array keywords. If no PIN extraction method is specified in the rule_array, the specified delimiter (padding) determines the PIN length.
  • If the input PIN block format is 3621, the specification of a PIN extraction method for the 3621 is supported through rule_array keywords. If no PIN extraction method is specified in the rule_array, the specified delimiter (padding) determines the PIN length.
  • If the input block format is ECI format 2, the PIN is always the leftmost 4 digits.

If the maximum PIN length allowed by the output PIN block is shorter than the extracted PIN, only the leftmost digits of the extracted PIN that form the allowable maximum length are placed in the output PIN block. The PIN length field in the output PIN block, it if exists, specifies the allowable maximum length.
