NFC Tag Reader Writer Kit with Arduino Uno + LED
NFC Tag Reader Writer Kit with Arduino Uno + LED — Write NDEF Text Records and Verify with a Phone Tap
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 writing a hidden text message onto a blank NFC sticker, then tapping it with a friend’s phone to reveal what you wrote — no app required, just the magic of near-field communication. This kit turns an Arduino Uno, a PN532 NFC module, and an OLED display into a dedicated NFC tag reader/writer that encodes standard NDEF text records onto supplied tags, giving you a hands-on peek into contactless data exchange.
What You'll Build
You’ll assemble a compact device that can both read and write NDEF-formatted text onto 13.56 MHz NFC tags. The OLED screen shows what’s currently stored on a tag, and any NFC-enabled Android or iOS phone can instantly verify the record with a simple tap. Use it to program tags that launch a website, share a WiFi password, or just surprise someone with a scannable greeting.
What You'll Learn
- How to interface the PN532 NFC module with Arduino using I2C or SPI
- Reading and writing NDEF text records programmatically
- Driving a 0.96-inch OLED display over I2C to show tag content
- Understanding NFC tag memory, UID, and block structure

Who This Kit Is For
Perfect for CBSE Class 11–12 students exploring communication protocols, B.Tech ECE/EEE final-year mini-projects, Smart India Hackathon teams prototyping NFC solutions, and ATL Tinkering Lab instructors introducing RFID concepts. Hobbyists aged 10 and up who have tinkered with Arduino will find it 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.
What if I get stuck during the build?
Scan the QR code included in the box to chat with our AI companion trained on this exact kit; it will walk you through wiring, code, and debugging. If you still need help, WhatsApp us and a real engineer will respond.
Can I write other types of data, like URLs or contact cards?
Absolutely — the PN532 library supports NDEF URI and Smart Poster records. The kit includes example sketches for text, URLs, and basic vCard entries so you can adapt them easily.
Does this work with all NFC phones?
The tags are NTAG213, which are readable by any Android or iOS device with NFC (iPhone 7 and later running iOS 13+). Writing capability from a phone depends on the app, but the Arduino unit writes all formats.
What age is truly appropriate for this kit?
The build is rated for ages 10+ with supervision; the coding involves copy-pasting and simple modifications. Younger makers (5–9) can participate with an adult handling the wiring and IDE setup.
PN532 NFC module reads and writes NDEF text records on NFC tags. Phone tap confirms record.
