RFID Attendance Logger
Smart Home · Board: ESP32 · Day 73 of 100
An ESP32 logs RFID taps straight into Google Sheets. Attendance tracking with zero paperwork.
How it works
Each RFID tap triggers an HTTPS request that appends a row — card ID plus timestamp — to a Google Sheet. The ESP32 handles the card reading locally and lets the spreadsheet do the record-keeping. Attendance tracking with zero paperwork and a free cloud database.
What you'll learn
- Google Sheets API
- Cloud spreadsheet logging
- Timestamped event records
- Paperless attendance systems
