Arduino with Parallax RFID reader storing variables in char

I am quite new to electronics and have been tinkering around with this Arduino UNO w/ WiFi Shield and the Parallax RFID R/W Module.

Link to the RFID Module: http://www.parallax.com/Store/Accessories/CommunicationRF/tabid/161/ProductID/688/List/0/Default.aspx?SortField=ProductName,ProductName

Link to it's Data Sheet:
http://www.parallax.com/Portals/0/Downloads/docs/prod/rf/28440-RFIDReadWrite-v1.0.pdf

So currently I have been using code I have found on the Arduino Playground, which I have adapted.

Namely: http://playground.arduino.cc/Learning/ParallaxRFIDreadwritemodule

Also: http://playground.arduino.cc/Learning/PRFID

(The latter is the older Read-Only module but proved helpful because of the error checking involved).

Objective:
To be able to read a tag, successfully store in a char array, or whatever is most appropriate, byte format would be preferable as so not to loose any smaller numbers when converted to DEC. I also need the value from the array to be assigned to another value so that the array can then be flushed for the presence of another card.

I have a semi-working program, However the serial monitor displays garbage

Initialised Serial Port at 9600bps
Initialising SD card...
SD card initialisation done.
Nothing to clear on SD card.
Code is: üÖ©ÿÿÿÿÿÿ
Code is: üºÿÿÿÿÿÿ

I have a feeling it is to do with a stop bit after the array has been filled but cannot be sure. I am 100% sure my Serial monitor is set to the correct baud 9600.

Code:

#include <SoftwareSerial.h> // SoftwareSerial to power the serial communications;
/** End inclusion of libraries
    */

#define RFID_READ 0x01 // Enable READ
#define RFID_WRITE 0x02 // Enable WRITE
#define ERR_OK 0x01 // Error checking
#define STOP_BYTE 0x0D // last byte recieved from a tag
#define CODE_LEN 11 // length of code
#define TERMINATOR 0x00
#define txPin 6 // Enable digital pin 6
#define rxPin 8 // Enable digital pin 8

#define readMemorySector 32 // Define variable for accessing various memory sectors on a card

// Initialise SoftwareSerial to input and output pins for mySerial
SoftwareSerial mySerial(rxPin, txPin);

//int val; // Buffer to store value when reading from a card, before printing to the serial monitor
int runs = 0; // Run counter
char code[CODE_LEN];
int bytes_read = 0;

void setupRFIDREAD()
{
   /** Set up RFID READ
   */
  mySerial.begin(9600); // initialises the rxPin and txPin using mySerial
  pinMode(txPin, OUTPUT); // defines txPin as OUTPUT   
  pinMode(rxPin, INPUT);  // defines rxPIN as INPUT

  //digitalWrite(6, LOW); // Enable reader

      /** Set up SD Card
  */
  Serial.println(F("Initialising SD card...")); // Initialising SD Card 

  pinMode(10, OUTPUT); //Initialises the sdPin as an output, even if it's not used
  digitalWrite(10, HIGH); // Disable WiFi SPI link before starting the SD cards as both use the same SPI Bus

  if (!SD.begin(4)) { // see if the card is present and can be initialized:
    Serial.println(F("initialisation failed, card faulty or not present!"));
    return; // don't do anything more
  }

  Serial.println(F("SD card initialisation done."));

  //clear the SD card
  if (SD.exists("test.txt")) {
    SD.remove("test.txt");
    Serial.println(F("SD card cleared."));
  } else {
    Serial.println(F("Nothing to clear on SD card."));
    return;
  }

}

void loopRFIDREAD()
{
  int val;    

  mySerial.print("!RW"); //To communicate with the RFID Read/Write Module, the user must first send a three-byte header string of !RW (in ASCII), followed by the desired single-byte command (in hexadecimal).
  mySerial.write(byte(RFID_READ)); //Initiates the read function.
  mySerial.write(byte(readMemorySector));  // Indicates which memorySector is to be read. In this case 32 which is the unique identifier.

  if(mySerial.available() > 0) {
    if((val = mySerial.read()) == ERR_OK){
      bytes_read = 0;
      while(bytes_read < CODE_LEN) {
        if(mySerial.available() > 0) {
          val = mySerial.read();
            if(( val == ERR_OK) || (val == STOP_BYTE))
              break;
    code[bytes_read] = val;
    bytes_read++;
  }
  }

 if(bytes_read == CODE_LEN) {
    Serial.print("Code is: ");
    Serial.println(code);
  }
  bytes_read = 0;

    digitalWrite(6, HIGH); // Disable reader as not to flood it
// Delay 750 milliseconds before next read and print cycle
delay(750);
    digitalWrite(6, LOW); // Enable reader
}
}
}

Please ignore the SD card functionality as that is used for another part of the program.

As you can see I have changed the code drastically from the code provided on the playground for this R/W module as the code looped without any checks and made it very difficult to control the output. Therefore I combined the code from the earlier version of the reader.

So then end goal for this is to be able to read and store a fob's ID into this char array, which will then be queried to a web server for additional data.

Hope you can help, if in need of any more detail please ask.
