Close Express when you need to

Payment methods, in the portal menu, now has GPO.

Closing the live terminal is for a security incident. It asks for your password. Express charges and refunds stop, and checkout no longer offers Express. The daily open does not turn it back on.

You open it again from the same page, with your password. A merchant admin can do that too, and so can BambooPay. After it is open, the daily cycle goes back to closing and opening the terminal each day.

Someone who can only view the terminal sees whether it is open or closed, and the last error. They cannot change it. Sandbox checkout still offers Express. This terminal is the live one.
