ISO8583 and Transaction Processing: Module 2 - Intermediate

Learn how and when the different ISO fields are used.

Continue your journey into the exciting world of payment transactions with the 2nd module of our flagship course "ISO 8583 and Transaction Processing", and learn how and when the different ISO fields are used.

The complete course puts you on a track to become an expert at understanding how payment transactions work, from terminal to issuer.

The 4 modules together build up our "ISO 8583 and Transaction Processing" course, and are equivalent to a 3- to 4-day course with a highly experienced instructor, and learning outcomes are reached with taught lessons, quizzes and 22 practical exercises for the guided parsing and analysis of many messages.


ISO8583 Module 2 is an 8-hour technical course that takes a deep dive into the different ISO fields, and explains how and when they are used.

Intended audience

This 2nd module is quite technical, and can be taken by anyone with basic IT knowledge who wants to start a journey towards payment transaction expertise. We strongly advise completing Module 1 before taking this Module 2.

The course was built with the following audience in mind: people who need strong, technical, payment transaction processing knowledge to be effective and efficient in their work. This includes developers, QA, customer support and managers in the following areas:

  • Acquirer host
  • Payment processor switch
  • Issuer host
  • Payment terminal integration
  • Troubleshooting transaction failures for banks or acquirers
  • Chip card issuance
  • Consulting in any of the areas above

Unique learning approach

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 2 course starts with by some technical fundamentals; this is to ensure that students have a solid IT base for ISO 8583, and is supplemented with practical exercises.

The course then covers bitmaps and length and format indicators. Those courses are supplemented with practical exercises so that students can apply those concepts.

The journey continues with an in-depth review of all the ISO 8583 data elements, looking at the 1987 and 1993 norms and at how they are used in practice in the industry. This is also supplemented with practical exercises, to help students grasp how those data elements are structured. The capstone of this review is a course on message parsing, where students learn how to extract information from a raw ISO 8583 message, and perform parsing themselves. And the in-depth journey on ISO 8583 finishes with explanations on data element presence in messages.

I have a passion for helping people reach their full potential. As a strong believer of the concept of sustainable leadership, I can feel the pain of employees who cannot perform at their best because of the difficulty of knowledge transfer. In my previous role in product marketing for a very complex payment simulator, I was faced with bridging this knowledge gap on a regular basis. The payment industry is one where the barrier to entry is high, and it should not be this way because it hinders growth for everyone.

My most prized accomplishment in my career is the development of a formalized payment education program for South Africa, which has seen over a hundred students with IT backgrounds turned into payment experts able to proficiently operate our payment simulator. This was made possible thanks to many other education experiences, technical or process-oriented.

Because I am an INTJ in the Myers-Briggs model, you can be sure that the content of my courses is fully thought-out and takes into consideration all aspects needed to reach the targets. I am really good at putting myself in my students’ shoes, to find the path that will take them from where they are to where they want to be.

Want to know more about my credentials?

During my 10 years of strong, technical experience in the card payment industry, I worked in development and QA for the two leading chip card manufacturers, Gemalto and Oberthur. I also held a position of security analyst for EMV products in a lab, which provided a deep understanding of the internal working of payment cards.

My longest position was with Acquirer Systems, a small company which created the best, and most complete, payment simulator on the market (it now belongs to UL). During that time, I held just about every position that there is to fill in a small company, doing software development, QA, customer support, then moving to consulting, pre-sales and education. I built a complete library of deep, technical knowledge in all aspects of card payment transactions, from the card in your pocket to the authorization by the banks.

I am also fully qualified for the positions I have held until now, and fully prepared for the challenges of the future. I hold an MSc in engineering from a French college, and an Executive MBA from Trinity College Dublin.
