Trustly is incredibly simple and quick to set up. First, players need to register with Trustly through their online casino or a supported banking provider. After the registration is complete, players can then use this method in order to make payments. Players simply need to select the desired payment option, enter the relevant account details, and confirm the payment. It is important to note that Trustly is not currently supported by all banks in South Korea, so it is best to double-check with the casino or your banking provider first.
