## Cancelling a Payment

In the transaction overview, it is possible to cancel a payment or issue a refund to the customer. To do this, select the relevant transaction and then choose "Cancel."

If the customer wishes to make the payment again, they can simply tap their card on the device once more. If the payment needs to be definitively canceled, this action must be carried out via the backend.
