``advertisedServices = setOf(ServiceInfo(ServiceType.corda.getSubType("issuer"))))``

``advertisedServices = ["corda.issuer.USD"]``

This allows for 3rd party applications to perform actions based on Node Type.

For example, the Explorer tool only allows nodes of this type to issue and exit cash.

In the "Bank Of Corda Demo: Run Issuer" window, you should see the following progress steps displayed:

- Awaiting issuance request

- Self issuing asset
