ISO 8583 Node Path Syntax

ISO 8583 is a financial transaction card originated messaging format used for exchanging electronic transaction information associated with payment (debit and credit) cards. ISO 8583 is a flat format which consists of a message Type indicator and fields which are referenced by a field number. The ISO 8583 node path syntax conforms to the following pattern.
