ISO 8583 Financial transaction card originated messages — 'Interchange message specifications' is the International Organization for Standardization standard for systems that exchange electronic transactions made by cardholders using payment cards. The ISO8583 standard specifies a message format that describes credit card and debit card data that is exchanged between devices and card issuers.

Capture Filter

You cannot directly filter ISO 8583-1 messages while capturing. However, if you know the TCP port used (see above), you can filter on that one.


How do I know if my Wireshark version supports dissection of ISO 8583-1 packets ?
