IoT Based Smart RFID Attendance System using ESP8266

📡 IoT-Based Smart RFID Attendance System using ESP8266 & Google Spreadsheet

This project utilizes the ESP8266 NodeMCU, MFRC522 RFID reader, and Google Spreadsheet to create a seamless, contactless attendance system. When an RFID card is tapped 🪪 on the reader, the ESP8266 reads the card data and sends it 📤 over Wi-Fi to a pre-configured Google Spreadsheet via Google Apps Script. Each entry is automatically logged with date and time 🕒, enabling real-time attendance tracking 📊 with minimal human intervention. Ideal for schools, colleges, and offices looking to digitize their attendance process efficiently. ✅
