Need a smart attendance system for your school, college, or office?
I build a complete RFID attendance system:
You receive: full source code (ESP32 + PHP + MySQL), wiring diagram,
setup guide, and a short video call to help you install it.
Platform:
ESP32
Sensors:
RFID
Expertise:
IoT
Do you supply the hardware?
No. The buyer buys the ESP32, RC522, LCD, LEDs and buzzer. I send a parts list.
Do I need WiFi?
No. A USB cable is enough.
How many students can it handle?
Thousands. The database can store a lot of data.
