Building Access Log with CSV Export
Build Your Own RFID Access Log Station with CSV Export – Arduino Mega Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Secure your lab, office, or classroom with a DIY RFID access logger. This advanced kit lets you build a standalone station that records every entry and exit — complete with username, timestamp, and automatic monthly CSV reports — all powered by an Arduino Mega.
What You'll Build
A fully functional RFID access logging unit with a 16x2 LCD display. Tap an RFID card to log an entry; tap again to log exit. All events are saved to a microSD card as a CSV file. At month-end, plug the card into your laptop and run a Python script to generate a clean monthly report — perfect for attendance tracking or security audits.
What You'll Learn
- Interfacing MFRC522 RFID reader with Arduino Mega and reading card UIDs
- Displaying real-time status on a 16x2 LCD over I2C backpack
- Using DS3231 RTC to timestamp events accurately
- Logging structured CSV data to a microSD card for later analysis
- Writing a Python script to parse the CSV and generate monthly usage reports
- Basic electronics assembly and soldering for durable prototypes

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify voltage levels, pin mappings, and library conflicts across modules | Pre-tested as a system — Arduino Mega, MFRC522, RTC, SD all work together flawlessly |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Engineering students building smart attendance systems for B.Tech ECE/EEE projects, participants in Smart India Hackathon designing IoT security prototypes, and ATL Tinkering Lab coordinators upgrading to advanced RFID data logging. The soldering and Python scripting make it ideal for final-year projects at IIT, NIT, VIT, or BITS.
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.
What if I get stuck during the build?
Scan the QR code on the box for instant access to the AI companion trained on this exact project. You can also reach our WhatsApp support team with photos of your circuit.
Does the Python export script work on Windows and Mac?
Yes, the provided Python script is platform-independent. You need Python 3.6+ and the pandas library. A requirements.txt is included.
Can I use my own RFID cards or key fobs?
Absolutely. The MFRC522 reader is compatible with any 13.56 MHz card or tag. The kit includes 10 cards to get started, but you can program additional ones.
How many access log entries can the microSD card hold?
A typical 4 GB microSD card (not included) can store millions of entries. Even with daily use, it will last years. The CSV file is lightweight and easy to back up.
RFID logs every entry and exit with username and timestamp to SD. Python script exports monthly CSV report.
