sendVerifiedAPDU

public ResponseAPDU sendVerifiedAPDU(SlotChannel slotchan,
                                     CommandAPDU command,
                                     CHVControl control,

                                     CardServiceInvalidCredentialException
Queries for a PIN and sends it to the smartcard. This method expects a command including a PIN to send to the smartcard. The PIN or password within the command is pre-initialized with padding bytes. This method queries the password from the user, stores it in the command, and sends the resulting command to the smartcard. The smartcard's response is returned.
This method is invoked by CardChannel.sendVerifiedAPDU only if the card terminal does not take responsibility for querying and filling in the password. If the terminal implements the interface VerifiedAPDUInterface, the channel will use the card terminal to do the job.
Parameters:
slotchan - the physical channel to the smartcard
command - the APDU to send, password still missing
control - the parameters needed to query and fill in the password, for example the message for querying, and an offset in the command APDU
dialog - a dialog provided by the application, or null to use a default dialog
Throws:
CardTerminalException - An error occurred while sending the command.
CardServiceInvalidCredentialException - The user entered an empty password, or cancelled the password input. No command has been sent to the smartcard.
