DESCRIPTION

This module was originally generated from the IBAN_Registry.pdf document supplied by SWIFT version 45 (April 2013) and updated to version 54 (January 2015).

All functions are exported by default.

iban_db()

Returns a reference to the "database" of known IBAN entities, keyed on the two letter code for participating countries (See ISO 3166 alpha 2 codes).

numify_iban($iban)

Put the first four characters at the end of the string. Transform all letters into numbers. This results in a string of digits [0-9] that can be used as a number.

mod97($number)

Returns the remainder of division by 97.
