Your Coherent card terminal will already be configured to be used with your Collums account but when you receive it, you will need to set it up.
Follow the set up instructions here.
In Collums, you need to ensure that you select your card terminal by going to Admin > Settings > Coherent Settings and choosing the terminal from the dropdown.
These instructions will also tell you how to take a payment using your card terminal but also read this article on how to take a payment in Collums with your integrated card reader.
If you have any problems with your terminal, contact Coherent:
