Message Implementation Guide

...

Purpose

The message implementation guide (MIG) is designed to assist the implementers of the messaging specification by providing worked examples as to how the message fields should be completed in different scenarios.

The intention is that this will better ensure consistency. This guide should be read alongside the data dictionary which provides fuller information about the rules, constraints and guidelines that should be adhered to when populating the fields.

Format Notation

The format that we use in this document for field value assignment is:-

[] enclose a set of field values.

Where there are multiple records for a particular field, we depict this as [<record 1 value1>,< record 1 value2>…<recordn valuen>], whilst where we are showing that there is 1 field value in 1 record, and another field value in a 2nd record, I depict this as [<record1 value1>],[<record 2 value 1>],[<record 3 value 3>]

, seperates individual field values within a field value set.

“ surrounds a text or date field value.

Implementation Notes

Before implementing the message standard, it is useful browsing current ATM Locator websites e.g. Link ATM Locator/, Visa ATM Locator and Mastercard ATM Locator, along with the ATM Locator webpages provided by your own organisation, in order to get a feel as to why you need to supply this information.
