# ESP-NOW RFID Display

Day 75 of the 100 Days 100 IoT Projects collection. Board: ESP8266.

One ESP8266 scans RFID cards while another shows results on an OLED over ESP-NOW. Split sensing and display wirelessly.

## How it works

The system splits in two: one ESP8266 scans RFID cards, the other drives an OLED. Scan results hop between them over ESP-NOW, so the display can sit far from the reader with no wires. Sensing and presentation, decoupled by radio.

## What you'll learn

- Split sensing/display architecture
- Wireless display updates
- Distributed UI design
- ESP-NOW data forwarding
