I have a new terminal? Do I need to do anything? 

What to do if you change your payment terminal

If it’s only the terminal that has changed and the Merchant ID has remained the same then no action is required.

If however you have also changed the Merchant ID, then you will need to do a test transaction to process a declined payment. This is called a 'Re-swipe'. 

This can be done by contacting support@mi-cnx.com and we will arrange a form to be provided for you.
