Java™ Smart Card I/O API
This specification describes the Java Smart Card I/O API defined by
JSR 268.
It defines a Java API for communication with Smart Cards
using ISO/IEC 7816-4 APDUs. It thereby allows Java applications to interact with
applications running on the Smart Card, to store and retrieve data
on the card, etc.
The API is defined by classes in the package
javax.smartcardio. They can be classified as follows:
- Classes describing the corresponding Smart Card structures
-
ATR,
CommandAPDU,
ResponseAPDU
- Factory to obtain implementations
-
TerminalFactory
- Main classes for card and terminal functions
-
CardTerminals,
CardTerminal,
Card,
CardChannel
- Supporting permission and exception classes
-
CardPermission,
CardException,
CardNotPresentException
- Service provider interface, not accessed directly by applications
-
TerminalFactorySpi
API Example
A simple example of using the API is:
// show the list of available terminals
TerminalFactory factory = TerminalFactory.getDefault();
List<CardTerminal> terminals = factory.terminals().list();
System.out.println("Terminals: " + terminals);
// get the first terminal
CardTerminal terminal = terminals.get(0);
// establish a connection with the card
Card card = terminal.connect("T=0");
System.out.println("card: " + card);
CardChannel channel = card.getBasicChannel();
ResponseAPDU r = channel.transmit(new CommandAPDU(c1));
System.out.println("response: " + toString(r.getBytes()));
// disconnect
card.disconnect(false);
