Arduino RFID Card Reader Logger Kit: Your First Step into NFC Communication

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

With this kit, you will assemble a real‑world RFID card reader that scans MFRC522‑compatible cards, reads each card’s unique ID, and displays it alongside a live timestamp on a 16×2 LCD screen. It’s the same fundamental technology behind metro cards, hotel key fobs, and attendance systems — now in your hands as a beginner‑friendly Arduino project.

What You'll Build

You will build a standalone RFID logger: each tap of a card lights up the LCD with the card’s UID and the exact time it was scanned. The breadboard‑based circuit uses the SPI protocol between the Arduino Uno and the MFRC522 module, and an I2C backpack keeps the LCD wiring to just four pins. Once assembled, you can use it to track card usage, create a simple access logger, or expand it with a buzzer for entry alerts.

What You'll Learn

• SPI communication between an Arduino Uno and an MFRC522 RFID reader
• Reading and displaying the unique UID from MIFARE classic RFID cards
• Interfacing a 16×2 LCD via an I2C backpack for compact data output
• Generating a real‑time timestamp using Arduino’s millis() function for event logging

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for young makers aged 10–15, this kit fits perfectly into ATL Tinkering Lab projects and CBSE Class 5–9 electronics exploratories. It is also an excellent gift for curious kids who want to see how NFC technology works hands‑on, without any prior soldering or complex coding.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
