Build an RFID Attendance Logger with Arduino Uno: SD Card Storage, LCD Display, and Python Weekly Reports

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

Imagine a classroom or office where every arrival is automatically recorded with a tap of a card, complete with names and exact timestamps stored on an SD card. At the end of the week, a single Python script generates a tidy attendance report. This kit gives you all the hardware and code to build exactly that - a fully functional RFID attendance system using an Arduino Uno, MFRC522 reader, RTC, and LCD display.

What You'll Build

You'll construct a standalone device that displays who scanned their card on a bright 16x2 LCD, saves the log to a microSD card, and lets you pull out the card to run a Python script on your computer for a formatted weekly report. It's a complete attendance solution you can demo at school, college, or a tech event.

What You'll Learn

• Interfacing MFRC522 RFID reader with Arduino Uno and reading card UIDs
• Using DS3231 real-time clock to timestamp each card scan precisely
• Saving structured data (name, timestamp) to a microSD card via SPI
• Generating a weekly attendance report in Python by reading the SD log file

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11-12 students building a computer science project, B.Tech ECE/EEE undergraduates prototyping an attendance system for hackathons like Smart India Hackathon, or ATL Tinkering Lab innovators who want a practical IoT gadget. Even hobbyists at IIT/NIT/VIT/BITS maker spaces will find this a satisfying weekend build.

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.
