libbusiness-creditcard-perl - 0.36-1 main

Business::CreditCard tell you whether a credit card number is
self-consistent -- whether the last digit of the number is a valid
checksum for the preceding digits.
.
The validate() subroutine returns 1 if the card number provided passes
the checksum test, and 0 otherwise.
.
The cardtype() subroutine returns a string containing the type of
card: "MasterCard", "VISA", and so on.
.
The generate_last_digit() subroutine computes and returns the last
digit of the card given the preceding digits. With a 16-digit card,
you provide the first 15 digits; the subroutine returns the sixteenth.
