Dear All!
I am doing a project on Student Management System with RFID attendance system. For the RFID attendance i connected the RFID to the nodemcu. The attendance data should be located in the web server database. So that what i have to do?
Do i go with the mqtt? or changing the xampp ip in that way?
Can You please suggest me with the solution? I don't have enough time.

Is this the sort of thing you are asking about?
The best way to record the attendance data is on some IoT cloud like Adafruit IO, Google firebase, Thingspeak, Googlesheet etc.
Its easiar to use Thingspeak with ESP8266, but attendance look more clean in spreadsheet.
So for NodeMCU to save the data on google sheet, you first have to create google spreadsheet, then create a Google script and Deploy it as web app. There are few scripts are available for this purpose.
Then finally with the help of PushBoxAPI, you can log the data from NodeMCU to googlesheet from anywhere via internet.
This image is from this iot attendance system, where the full process is described.
Its a bit lengthier process but not complex, as you already connected RFID with nodemcu, just check the connect the ESP with internet and use google script from the link to log the data.
