Implementation of CardTerminal.internalReset().

Specified by:

internalReset in class CardTerminal

Parameters:

slot - The slot number of the slot to be resetted.

ms - To be ignored. If the card does not respond within the time specified for the protocol an exception should be thrown.

Returns:

The CardID of the card.

Throws:

CardTerminalException - thrown in case of errors during reset

internalReset

protected CardID internalReset(int slot,
                               boolean warmReset)
                        throws CardTerminalException

Implementation of CardTerminal.internalReset(int slot, boolean warmReset).

Overrides:

internalReset in class CardTerminal

Parameters:

slot - The slot number of the slot to be resetted.

Returns:

The CardID of the card.

Throws:

CardTerminalException - thrown in case of errors during reset

isCardPresent

public boolean isCardPresent(int slot)
                      throws CardTerminalException

Check whether there is a smart card present.

Specified by:

isCardPresent in class CardTerminal

Parameters:

slot - Number of the slot to check (must be 0 for PCSC)

Returns:

True if there is a smart card inserted in the card terminals slot.

Throws:

CardTerminalException - thrown in case of problems getting the status from CardTerminal (or other serious problems in the terminal).

getCardID

public CardID getCardID(int slot,
                        int timeout)
                 throws CardTerminalException
