ISO8583 and Transaction Processing: Module 1 - Beginner

Learn about the different message types and their processing flow.

Begin your journey into the exciting world of payment transactions with the 1st module of our flagship course "ISO 8583 and Transaction Processing", and learn about the different message types and their processing flow.

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 1 is a 2-hour high-level course that paints the big picture of card payment and teaches the different message types and their processing flow.

Intended audience

This 1st module is not very technical, and can be taken by anyone who wants to start a journey towards payment transaction expertise.

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 1 course starts with the big picture: the non-technical, high-level information. Then students start their journey into the technical aspects of ISO 8583 with an overview of how messages are structured, followed by a course on Message Type Identifiers and explanations on transaction flows.

The course finishes with a high-level view of how EMV and contactless transactions work, as well as how online PIN is processed.

Those constitute the building blocks needed to continue to the second module of the complete course.

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.
