NFC Card – MIFARE Classic 13.56MHz

White PVC NFC Card – MIFARE Classic 1K Chip (13.56MHz)

Overview:

The White PVC NFC Card with a MIFARE Classic 1K chip is a contactless smart card operating at 13.56MHz, ideal for use in RFID and NFC applications such as access control, attendance systems, payment terminals, and identification. It is compatible with standard NFC readers like MFRC522, PN532, and smartphones that support MIFARE technology.

Key Features:

• Based on MIFARE Classic 1K chip

• Operates at 13.56MHz (ISO/IEC 14443 Type A)

• 1KB EEPROM memory divided into 16 sectors

• Each sector secured by two keys (A & B) with read/write access conditions

• Fast and secure communication – supports anti-collision and mutual authentication

• High-quality white PVC finish – printable, waterproof, and durable

• Compatible with most Arduino RFID modules and access control systems

Technical Specifications:

Wiring Example (with MFRC522 and Arduino Uno):

💡 Note: MFRC522 modules run on 3.3V only – do not connect to 5V.

Sample Code (Arduino with MFRC522):

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

#define RST_PIN 9
#define SS_PIN 10
MFRC522 mfrc522(SS_PIN, RST_PIN);

void setup() {
  Serial.begin(9600);
  SPI.begin();
  mfrc522.PCD_Init();
  Serial.println("Scan your NFC card...");
}

void loop() {
  if ( !mfrc522.PICC_IsNewCardPresent() || !mfrc522.PICC_ReadCardSerial() ) return;

  Serial.print("Card UID: ");
  for (byte i = 0; i < mfrc522.uid.size; i++) {
    Serial.print(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " ");
    Serial.print(mfrc522.uid.uidByte[i], HEX);
  }
  Serial.println();
  delay(1000);
}

Applications:

• RFID/NFC access control systems

• Smart identification and student cards

• Time and attendance tracking

• Cashless payment systems

• Loyalty and membership programs
