智能卡讀寫器，IC卡讀卡器

windows在java中使用JNI調(diào)用usb讀卡器的動(dòng)态庫yw60x.dll

public static void main(String[] args)
{	int ReaderID=1;	int Requestmode=38;	short Cardtype[]=new short[1];	byte LenSn[] = new byte[1];	byte CardNo[] = new byte[8];	byte Key[]=new byte[]{(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF};	byte BlockData[]=new byte[16];	YOWORFID rfidreader = new YOWORFID();	rfidreader.YW_USBHIDInitial();	int rt =0;	{	rt =rfidreader.YW_RequestCard(ReaderID,Requestmode,Cardtype);	//if(rt<=0)continue;	rt = rfidreader.YW_AntiCollide(ReaderID,LenSn,CardNo);	HexToStr(CardNo,LenSn[0]);	rt =rfidreader.YW_CardSelect(ReaderID,LenSn[0],CardNo);	rt =rfidreader.YW_KeyAuthorization(ReaderID,96,4,Key);	System.out.printf("KeyAuthorization=%d",rt);System.out.println();	rt =rfidreader.YW_ReadaBlock(ReaderID,4,16,BlockData);	System.out.printf("YW_ReadaBlock=%d",rt);System.out.println();	if(rt>0){HexToStr(BlockData,16);}	}	rfidreader.YW_Led(ReaderID,1,1,1,3,0);	rfidreader.YW_USBHIDFree();
