How to read the nfc tag and transfer the processing to the web server?

Question

PHP

Perhaps it looks wild, but the task is as follows:

There is a card with an nfc chip, which conditionally has some kind of code that we read with an nfc reader with a write function.
It is necessary to send this code to a site that processes and checks for the presence of this code in the database, and ideally sends a request to change the code in the chip or modify it.

I basically use the good old php, but if possible, write on what it’s really possible to do it, I’m ready to at least catch on to something. Thanks in advance !

Answer 1

Let's start with the fact that php in this question can only be used on the server (site).
Your nfc reader turns out to be a spherical horse in a vacuum.
This is most likely a device with a usb connection.
And here it is already necessary to start further from the SDK, which you can find on the manufacturer's website.
Since you have to write your application for the operating system and in the programming language from which you can call the found library.

Answer 2

read by nfc reader

which one? it will determine how you will receive this data and then how to upload it to the server
