Reply To: Mifare 1K to HEX

Hi Mike,

You can use this function to get byte array, after that, you can convert byte array to the string hex value:

    public static byte[] toByteArray(int data, int length){

        byte[] byteArr = ByteBuffer.allocate(INT_LENGTH).putInt(data).array();

        if(length!=INT_LENGTH)

            byteArr = Arrays.copyOfRange(byteArr, INT_LENGTH - length, INT_LENGTH);

        return byteArr;

    }
