MFRC522 + DESFire ev1 read problem

Projects Programming

Hi, i would like to ask if is possible to read UID card number from MIFARE DESFire EV1 card.
In specification is written that is supported, but I used example code from arduino nfc library, but nothing to do. Please can you help me what is wrong and how can I do to read UID?
UID in DESFire has 7B length.
I don't nead to read or write anything more.

Thanks

As a first step can you please post the code and details of the hardware and wiring that you used.

Hi, I use arduino UNO and this module:

Everything functioning in MIFARE classic card.

I used library rfid-master
GITHUB
I am trying to use this code:

#include <SPI.h>
#include <MFRC522.h>

#define SS_PIN 10
#define RST_PIN 9
MFRC522 mfrc522(SS_PIN, RST_PIN);	// Create MFRC522 instance.

void setup() {
	Serial.begin(9600);	// Initialize serial communications with the PC
	SPI.begin();			// Init SPI bus
	mfrc522.PCD_Init();	// Init MFRC522 card
	Serial.println("Scan PICC to see UID and type...");
}

void loop() {
	// Look for new cards
	if ( ! mfrc522.PICC_IsNewCardPresent()) {
		return;
	}

	// Select one of the cards
	if ( ! mfrc522.PICC_ReadCardSerial()) {
		return;
	}

	// Dump debug info about the card. PICC_HaltA() is automatically called.
	mfrc522.PICC_DumpToSerial(&(mfrc522.uid));
}

Thanks

seems that the reader is not compatible with desfire cards/tags. the following cards/tags also do not work for me:

Mifare Ultralight C MFOICU2, 7byte-UID
Mifare Classic 1K 'MF1 IC S5009'
Mifare DESFire EV1 (MF3ICD81)
Mifare Classic 1K (emulated)

Just this week I finished the mega project: My libraray is the FIRST Desfire EV1 library that has ever been written for the Arduino family. It uses the PN532 board from Adafruit.

This board has the advantage that it has a bigger antenna than usual. This allows to read the card from a larger distance than all those boards with a small antenna like the one on your foto.

The code has only been tested compiling for Teensy 3.2, but it should also work on other Arduino boards.

My code contains all you need to communicate with a Desfire EV1 card. I implemented 2K3DES, 3K3DES and AES encryption.
