I need help on RFID AND Bluetooth

Question

I a student trying to send the RFID tag code via Bluetooth to my android app, but I think the code I combined doesn't work, BUT when I test them separately they work. I am using an hc-06 and Sparkfun RFID Evaluation Shield(RFID Eval 13.56MHz) the hc-06 Bluetooth code is

#include <SoftwareSerial.h>
int SW = 13;
void setup()
{
pinMode(SW, INPUT_PULLUP);
Serial.begin(9600);
}
void loop() {`enter code here`
  if (digitalRead(SW) == HIGH) {
  Serial.println("0");
  delay(500);}
  else if (digitalRead(SW) ==LOW) {
    Serial.println("1");
    delay(500);}
}

and the Rfid reader code is

#include <SoftwareSerial.h>

SoftwareSerial rfid(7, 8);
SoftwareSerial xbee(10, 9);

//Prototypes
void check_for_notag(void);
void halt(void);
void parse(void);
void print_serial(void);
void read_serial(void);
void seek(void);
void set_flag(void);

//Global var
int flag = 0;
int Str1[11];

//INIT
void setup()
{
  Serial.begin(9600);
  Serial.println("Start");

  // set the data rate for the SoftwareSerial ports
  xbee.begin(9600);
  rfid.begin(19200);
  delay(10);
  halt();
}

//MAIN
void loop()
{
  read_serial();
}

void check_for_notag()
{
  seek();
  delay(10);
  parse();
  set_flag();

  if(flag = 1){
    seek();
    delay(10);
    parse();
  }
}

void halt()
{
 //Halt tag
  rfid.write((uint8_t)255);
  rfid.write((uint8_t)0);
  rfid.write((uint8_t)1);
  rfid.write((uint8_t)147);
  rfid.write((uint8_t)148);
}

void parse()
{
  while(rfid.available()){
    if(rfid.read() == 255){
      for(int i=1;i<11;i++){
        Str1[i]= rfid.read();
      }
    }
  }
}

void print_serial()
{
  if(flag == 1){
    //print to serial port
    Serial.print(Str1[8], HEX);
    Serial.print(Str1[7], HEX);
    Serial.print(Str1[6], HEX);
    Serial.print(Str1[5], HEX);
    Serial.println();
    //print to XBee module
    xbee.print(Str1[8], HEX);
    xbee.print(Str1[7], HEX);
    xbee.print(Str1[6], HEX);
    xbee.print(Str1[5], HEX);
    xbee.println();
    delay(100);
    //check_for_notag();
  }
}

void read_serial()
{
  seek();
  delay(10);
  parse();
  set_flag();
  print_serial();
  delay(100);
}

void seek()
{
  //search for RFID tag
  rfid.write((uint8_t)255);
  rfid.write((uint8_t)0);
  rfid.write((uint8_t)1);
  rfid.write((uint8_t)130);
  rfid.write((uint8_t)131);
  delay(10);
}

void set_flag()
{
  if(Str1[2] == 6){
    flag++;
  }
  if(Str1[2] == 2){
    flag = 0;
  }
}

and the code I combined is

#include <SoftwareSerial.h>

SoftwareSerial rfid(7, 8);
SoftwareSerial xbee(10, 9);
SoftwareSerial BT(2, 3);

//Prototypes
void check_for_notag(void);
void halt(void);
void parse(void);
void print_serial(void);
void read_serial(void);
void seek(void);
void set_flag(void);

//Global var
int flag = 0;
int Str1[11];
int a=0;
char data[3];

//INIT
void setup()
{
  Serial.begin(9600);
  Serial.println("Start");
   BT.begin(9600);
  // set the data rate for the SoftwareSerial ports
  xbee.begin(9600);
  rfid.begin(19200);
  delay(10);
  halt();
}

//MAIN
void loop()
{
  read_serial();
}

void check_for_notag()
{
  seek();
  delay(10);
  parse();
  set_flag();

  if(flag = 1){
    seek();
    delay(10);
    parse();
  }
}

void halt()
{
 //Halt tag
  rfid.write((uint8_t)255);
  rfid.write((uint8_t)0);
  rfid.write((uint8_t)1);
  rfid.write((uint8_t)147);
  rfid.write((uint8_t)148);
}

void parse()
{
  while(rfid.available()){
    if(rfid.read() == 255){
      for(int i=1;i<11;i++){
        Str1[i]= rfid.read();
      }
    }
  }
}

void print_serial()
{
  if(flag == 1){
    //print to serial port
    Serial.print(Str1[8], HEX);
    Serial.print(Str1[7], HEX);
    Serial.print(Str1[6], HEX);
    Serial.print(Str1[5], HEX);
    Serial.println();
    //print to XBee module
    xbee.print(Str1[8], HEX);
    xbee.print(Str1[7], HEX);
    xbee.print(Str1[6], HEX);
    xbee.print(Str1[5], HEX);
    xbee.println();
    delay(100);
    ++a;
  sprintf(data, "%02d", a);
  BT.print(data);
  delay(1000);
    //check_for_notag();
  }
}

void read_serial()
{
  seek();
  delay(10);
  parse();
  set_flag();
  print_serial();
  delay(100);
}

void seek()
{
  //search for RFID tag
  rfid.write((uint8_t)255);
  rfid.write((uint8_t)0);
  rfid.write((uint8_t)1);
  rfid.write((uint8_t)130);
  rfid.write((uint8_t)131);
  delay(10);
}

void set_flag()
{
  if(Str1[2] == 6){
    flag++;
  }
  if(Str1[2] == 2){
    flag = 0;
  }
}

is the code I combined right or if not right can you tell me where the code is wrong.
