启动pcscd服务

$>service pcscd status

Java 版本

$>java -version
java version "1.7.0_03"
Java(TM) SE Runtime Environment (build 1.7.0_03-b04)
Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02,mixed mode)

示例 Java 程序

import java.util.List;
import javax.smartcardio.*;

public class PCSCTest {

public static void main(String[] args) {
try {

TerminalFactory factory = TerminalFactory.getDefault();
List<CardTerminal> terminals = factory.terminals().list();
System.out.println("Terminals list size ->"+terminals.size());
//System.out.println(terminals.get(0));

} catch(Exception e) {
e.printstacktrace();
}
}

}

结果是

terminals size-->0
