Namespace: Subsembly.FinTS.Online

Assembly: Subsembly.FinTS.Core.dll

public interface IFinCredentialForm

Remarks

The methods in this interface may be called from a background worker thread. Therefore all implementations must delegate all methods to the main UI thread.

Methods

GetCredential(FinContact, FinCredential)

Method to be invoked in order to prompt the user to provide some security credentials such as a PIN or TAN.

Declaration

bool GetCredential(FinContact aContact, FinCredential aCredential)

Parameters

Type	Name	Description
FinContact	aContact	Identifies the contact for which to obtain the security information. This is used to provide as much information to the user as possible.
