The learning path is one of increasing complexity, with building blocks to construct the ISO 8583 knowledge, and practical exercises and quizzes to keep students engaged. The complete course contains 22 practical exercises for the guided parsing and analysis of many messages.
The ISO8583 Module 3 course zooms out of the low-level structure of ISO 8583, and teaches students how to perform analyses of individual messages, starting with network management messages, really focusing on authorization request messages, and also looking at authorization advice, financial messages, and reversals. Practical exercises with many different transaction samples are provided to help the student construct real experience on message analysis.
The course then zooms out once more, and looks at the transactions from end to end. It follows ISO 8583 messages as they are generated by a payment terminal all the way to their authorization by a card issuer, going through the different message conversion processes, where the student can see the data elements that are converted, removed and added as the message is processed by each actor of the payment chain and potentially changes version of ISO 8583. Magstripe and contactless magstripe are covered.
