$>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
