 * Application code should not interact directly with this type, see {@link PollingInfo instead}.

 * When we send a request to the bank that requires a Verification of Payee, this means that the bank server has to
 * contact another bank's server and compare payee names. Especially for larger requests (e.g. bulk transfers), this can
 * take some time. During this time, the server asks the client to poll regularly in order to find out when the process
 * is done. This class contains the state that the client needs to do this polling.
