Rfid with Adafruit fingerprint together not working in Arduino Uno - arduino

Question

I am trying to create an ATM module using Arduino. Im using a RFID reader to scan the card and Adafruit Fingerprint Module for fingerprint verification. The issue is both work but not together. Here is my code:
#include <Key.h>
#include <Keypad.h>
#include <Adafruit_Fingerprint.h>
#include <SD.h>
#include <SPI.h>
#include<SoftwareSerial.h>
SoftwareSerial mySerial(0, 1);
SoftwareSerial mySerials(2, 3);
int read_count = 0, tag_count = 0;
int j = 0, k = 0; // Variabvles to iterate in for loops
char data_temp, RFID_data[12], data_store[12];
boolean disp_control;
char filename[4], fileText[30], names[10];
int atm[5];
uint8_t n, num, p;
char key;
int p1, p2, p3, p4, z;
char fid;
File myFile;
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerials);
const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
char keys[ROWS][COLS] = {
{'1', '2', '3', 'A'},
{'4', '5', '6', 'B'},
{'7', '8', '9', 'C'},
{'*', '0', '#', 'D'}
};
byte rowPins[ROWS] = {5, 4, 3, 2}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {9, 8, 7, 6}; //connect to the column pinouts of the keypad
Keypad keypads = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
void setup() {
finger.begin(57600);
mySerial.begin(9600);
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.print("Initializing SD card...");
if (!SD.begin(4)) {
Serial.println("initialization failed!");
while (1);
}
Serial.println("initialization done.");
Serial.println("Please Place Your Card");
}
void RecieveData()
{
if (mySerial.available() > 0)
{
data_temp = mySerial.read();
RFID_data[read_count] = data_temp;
read_count++;
}
}
void ReadData()
{
if (read_count == 12) {

for (j = 0; j < 12; j++) {

}
int x = 0;

filename[x] = data_store[i];
x++;
}
filename[3] = '.';
filename[4] = 't';
filename[5] = 'x';
filename[6] = 't';
filename[7] = '\0';
myFile = SD.open(filename, FILE_READ);
if (myFile) {
// read from the file until there's nothing else in it:
while (myFile.available()) {
for (int i = 0; i < 20; i++) {
fileText[i] = myFile.read();
}
int a, n = 0;
for (int i = 0; i < 4; i++) {
atm[a] = fileText[i];
a++;
}
for (int i = 5; fileText[i] != '\0'; i++) {
names[n] = fileText[i];
n++;
}
fid = fileText[4];
validate();
myFile.close();
}
} else {
// if the file didn't open, print an error:
Serial.println("error opening test.txt");
}
read_count = 0;
tag_count++;

/*z = finger.fingerID;

Serial.println("Success");
}
else {
Serial.println("Fail");

}
void loop() {
RecieveData();
ReadData();
getFingerprintIDez();
delay(50);
}
If I initialize in this format, then fingerprint works:
mySerial.begin(9600);
finger.begin(57600);
Serial.begin(9600);
And if i do it this way, then RFID works:
finger.begin(57600);
mySerial.begin(9600);
Serial.begin(9600);
I want both of them to work i.e; I first Scan the Card, then verify pin and then it checks the validity of the fingerprint. But the issue is only one of them works at a time. If RFID works, then fingerprint doesn't even blink and if Fingerprint works, RFID doesn't read.
I'm new to this and I don't know where I am going wrong.
