The card number alias (CNA). The CNA is a number that can be used to identify a card holder. The CNA is derived from the card number but has been obfuscated in such a way that it is not considered sensitive by the PCI standards.
The CNA is a string of hexadecimal digits, representing binary data.
Note! The terminal must be configured to calculate the CNA. If it is not, then this property will be empty. Contact your Westpay representative if you require access to this data.
