Updating a v0.23 RFID sketch to v1.0

Got ya. I'd like to build a bare bones read and print sketch.

First thing to do is see what comes back from the module:

void parse()
{
  while(rfid.available())
  {
    byte rfidVal = rfid.read();
    Serial.println(rfidVal, DEC);
  }
}

This will print every thing that the reader outputs. If this works, we can move on to reading the data properly, and then making use of the data.
