What is a Terminal ID & Merchant ID?

In New Zealand, each Merchant and EFTPOS terminal is assigned an individual ID number known as a Merchant ID (MID) or Terminal ID (TID). Your Merchant Number, provided by your Merchant Bank, links your terminal to your settlement bank account. A Terminal ID is a unique number associated with each terminal.

These ID numbers store essential information, such as the network your terminal is connected to and the accepted cards. At times, you may need to share these ID numbers with payment providers to identify your terminal or merchant facility.

How do I find these numbers?
