This is our last high school project and hopefully the best one.
As the name suggests this attedance system is based on RFID technology along with enchanced features like encryptiion, anti RFID-exploitation and improved security. We have used NodeMCU ESP8266 as micro controller and processor.The data is recieved from RFID tag through tag reader then gets uploaded to a google spreadsheet through NodeMCU. This makes the mundane job of attendance easier.
