ISCardVerify interface

[The ISCardVerify interface is available for use in the operating systems specified in the Requirements section. It is not available for use in Windows Server 2003 with Service Pack 1 (SP1) and later, Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The Smart Card Modules provide similar functionality.]

The following interface definition is provided as a standard that can be followed when developing a smart card service provider. The ISCardVerify interface provides services for setting CHV (card holder verification) code and for verifying the user.

The ISCardVerify class is defined for applications that implement application-specific CHV policy, and that have a detailed knowledge of the smart card's internal implementation.

Following is a typical use of the ISCardVerify interface.

The following procedure uses ISCardVerify to change the CHV code.

To change the CHV code of a smart card

  1. Create an ISCardVerify interface (through the corresponding ISCardManage interface method).
  2. Call the ChangeCode method and provide new code, specifying if it is local or global and if it is enabled or disabled.
  3. Release the ISCardVerify interface.


The ISCardVerify interface inherits from the IDispatch interface. ISCardVerify also has these types of members:


The ISCardVerify interface has these methods.

Method Description
ChangeCode Changes the current CHV code.
ResetSecurityState Resets the security context of the smart card.
Unblock Re-enables the security context.
Verify Authenticates the user.
