ISO8583 Training and Tutorials

ISO8583 Training

In the payments world, the standard is ISO8583. Of course, the standard is just a definition and you need to understand how it is used in the payments world. We can teach you about it, show how it is used, demonstrate it in practice and guide you in your own project.
Of course we can also explain it in relation to the Base24, Base24-eps and Way4 worlds.

The ISO8583 standard and the flavors

The standard is the baseline where it all starts, but the flavors out there are unlimited.

MCC Codes - Merchant Category Codes to use in ISO8583 Field 18

ATM MCC: 6011

This document contains lists of valid Merchant Category Codes (MCCs). MCCs are used to identify the type of business in which a merchant is engaged.

MCC Codes (or merchant category codes) are assigned to merchant accounts during the set up process and are used to differentiate between types of business & industries. Each industry has different transaction patterns and differing levels of risk (potential for fraud). MCC codes are used by issuing bank to determine if they will accept the transaction.

Enabling traces in the payments simulator

Enabling traces in the ISO8583 Payments Simulator, just like the ISO8583 message converter and the ISO8583 Host, is a call to the system core to write additional data. This will, most of the times, show raw data (binary data is dumped as hex) for better understanding what is going on, what data is actually being used.

Most importantly, enabling traces shows dumps of TCP traffic or actual data being written to files, queries do database and so on. This is to verify that you are sending the correct data.
