Direct Known Subclasses:
MFC35CHVProvider
public abstract class MFCCHVProvider
extends java.lang.Object

The CHV provider is responsible to query the user for a password. It is one of the helpers of MFCCardAccessor. A dialog may be set to use for the query.
Card holder verification requires exchanging APDUs with the smartcard. Since the command for this purpose may be card-specific, this base class must be abstract.
