How to detach a card reader in the Gateway Manager

If a merchant will not use a card reader that has been assigned to him anymore (e.g. because it got stolen, lost or returned), you need to detach the card reader from the merchant in the Gateway Manager.

Select the merchant from the list and click on the “Detach card reader” icon.

Confirm the dialogue to detach the card reader.

Now the merchant cannot use the reader anymore. If the merchant tries to use the reader, an error appears. See here.

The reader can be attached to another merchant.
