rfid module not working (rc522)

Question

i brought a rfid module which is rc 522 but when i upload the code it is not reading the card even when i upload example code i have returned it 2 times and got it replaced but the same problem may i know the solution

#include "SPI.h" // SPI library
#include "MFRC522.h" // RFID library (https://github.com/miguelbalboa/rfid)
const int pinRST = 9;
const int pinSDA = 10;
MFRC522 mfrc522(pinSDA, pinRST); // Set up mfrc522 on the Arduino
void setup() {
 SPI.begin(); // open SPI connection
 mfrc522.PCD_Init(); // Initialize Proximity Coupling Device (PCD)
 Serial.begin(9600); // open serial connection
}
void loop() {
 if (mfrc522.PICC_IsNewCardPresent()) { // (true, if RFID tag/card is present ) PICC = Proximity Integrated Circuit Card
 if(mfrc522.PICC_ReadCardSerial()) { // true, if RFID tag/card was read
 Serial.print("RFID TAG ID:");
 for (byte i = 0; i < mfrc522.uid.size; ++i) { // read id (in parts)
 Serial.print(mfrc522.uid.uidByte[i], HEX); // print id as hex values
 Serial.print(" "); // add space between hex blocks to increase readability
 }
 Serial.println(); // Print out of id is complete.
 }
 }
}

this is one of the many codes i used

• Nick Gammon: What gets printed? You have a lot of serial prints there, can you please edit the question and share what you see?
• Akshit Singh: i just see nothing
• Nick Gammon: Possibly you have wired it incorrectly. Without seeing any photos, links to the module you bought, or schematics, it is very hard, if not impossible, to say.
• Akshit Singh: SDA 10, SCK 13, MOSI 11, MISO 12, IRQ UNUSED, GND GND, RST 9, 3.3V 3.3V, i dont feel they are wrong
