Reading Data that was written in RFID tag

Projects General Guidance

void suppressAll()                                //suppresses the "null result" from being printed if no RFID tag is present
{
    if(mySerial.available() > 0)
    { mySerial.read();
      suppressAll();
    }
}

Recursive calls like this are not a good idea.

       {suppressAll();}

Both codes are taken from Arduino Playground - HomePage and are working properly.

Here's my problem, I want to read the data that has been written into the tag but I do not know how.

Is the first code working, or not. It looks like it reads all the data. Does it, or doesn't it?
