Whether you are building a door lock system, student attendance tracker, or smart locker — the MFRC-522 RFID kit is the most affordable and beginner-friendly way to add contactless card identification to your project in Bangladesh.⭐ Key Features��13.56MHz RFID FrequencyIndustry-standard frequency — compatible with MIFARE Classic cards��Complete Kit IncludedReader module RFID card key fob — ready to use immediately��SPI InterfaceFast SPI communication — works with all standard microcontrollers��Up to 60mm Read RangeReliable contactless reading within 60mm distance��3.3V Low Power OperationLow current draw — ideal for battery-powered access systems��Beginner FriendlyMFRC522 Arduino library — working UID reader in minutes�� What Can You Build With the MFRC-522?��RFID Door LockGrant access with tap of a card or key fob��Attendance SystemStudent or employee RFID attendance tracker��Smart Locker SystemRFID unlocking for cabinets and storage��️Asset TrackingTag and identify equipment or inventory items��Robotics & IoT AccessCard-based authentication for IoT systems�� Who Should Buy This?�� BeginnersBuilding a first access control or RFID project — the kit includes everything and the Arduino library is simple�� StudentsUniversity projects on smart access systems, IoT security, attendance tracking and embedded systems⚙️ EngineersPrototyping card-based authentication and identification systems for office or industrial use��️ HobbyistsDIY smart door locks, room access systems and RFID-based home automation projects⚔️ RC522 RFID vs PN532 vs RDM6300 — Which RFID Module Should You Use?Comparing the most popular RFID reader modules available for maker projectsFeatureTHIS ITEMRC522MFRC-522 KitADVANCEDPN532NFC Module125KHzRDM6300Low Freq ReaderFrequency13.56MHz13.56MHz125KHzInterfaceSPISPI / I2C / UARTUART (TTL)NFC Support❌ RFID only✅ Full NFC RFID❌ NoRead RangeUp to 60mmUp to 50mmUp to 100mmArduino Library✅ MFRC522 — simple✅ Adafruit PN532UART serial readBest ForAccess control, attendancePhone NFC advanced RFIDLong-range simple ID�� Features & SpecificationsFeature ⚙️Details��️ Product TypeMFRC-522 RFID Reader Module Kit�� Frequency13.56MHz�� InterfaceSPI (up to 10Mbps)�� Read RangeUp to 60mm⚡ Operating Voltage3.3V�� Supported CardsMIFARE Classic 1K / 4K, MIFARE Ultralight�� Compatible WithArduino, ESP32, ESP8266, STM32, Raspberry Pi�� Kit ContentsRC522 module RFID card key fob�� Library Setup & UID Reader Example1Install MFRC522 LibraryArduino IDE → Sketch → Include Library → Manage Libraries → Search MFRC522 by miguelbalboa → Install.2Wire to Arduino (SPI)RC522 SDA→10, SCK→13, MOSI→11, MISO→12, GND→GND, RST→9, 3.3V→3.3V on Arduino Uno. For ESP32 use default SPI pins (SS=5, SCK=18, MOSI=23, MISO=19). ��MFRC-522 Read Card UID Example#include <SPI.h> #include <MFRC522.h> #define SS_PIN 10 // SDA pin #define RST_PIN 9 MFRC522 rfid(SS_PIN, RST_PIN); void setup() { Serial.begin(9600); SPI.begin(); rfid.PCD_Init(); Serial.println("✅ Scan your RFID card..."); } void loop() { if (!rfid.PICC_IsNewCardPresent()) return; if (!rfid.PICC_ReadCardSerial()) return; Serial.print("Card UID: "); for (byte i = 0; i < rfid.uid.size; i ) { Serial.print(rfid.uid.uidByte[i] < 0x10 ? " 0" : " "); Serial.print(rfid.uid.uidByte[i], HEX); } Serial.println(); rfid.PICC_HaltA(); }Open Serial Monitor at 9600 baud. Tap the included card or fob to read its unique UID.❓ Frequently Asked Questions❓ Does the RC522 work at 5V or 3.3V?The RC522 operates at 3.3V only — do not connect VCC to 5V. However, most versions tolerate 5V logic on the SPI data pins when used with Arduino Uno. For safe operation, use a 3.3V microcontroller like ESP32 or add a logic level converter when using with 5V Arduino.❓ Can I add more RFID cards to the system?Yes — you can register multiple card UIDs in your code or store them in EEPROM. Each card has a unique 4-byte UID. Simply scan each new card, save its UID, and check against the stored list in your access control logic. Additional 13.56MHz RFID cards are available separately from Dream RC.❓ What is the MFRC-522 RFID Kit price in Bangladesh?The MFRC-522 RFID Card Module Kit price in BD is 169 BDT from Dream RC — the best price in Bangladesh with card and key fob included, fast delivery, and Cash on Delivery nationwide.�� You Will Also Need RFID Card 13.56MHzNeed extra RFID cards for more users?
