USB port question

[IvanoiuAlexandruPaul]

Hello my name is Alex. I am kinda new to flutter and I want to build an app that allows me to read and write on NFC tags. The problem is that the app must be Windows. I saw that you posted a flutter package for the serial port but I need USB in order to use the following product : https://www.amazon.it/Fydun-ACR122U-Lettore-contatto-software/dp/B07Y3C8XXZ/ref=sr_1_1_sspa?crid=39IV26IF4358A&keywords=nfc+reader&qid=1642976720&sprefix=nfc+%2Caps%2C90&sr=8-1-spons&psc=1&smid=A1A6WWKJ95BCLL&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzUUc4RkZFUVNNTFY3JmVuY3J5cHRlZElkPUEwMTY1NzE3Q0daTE5YNFJYNDZNJmVuY3J5cHRlZEFkSWQ9QTEwMDg4NDQxMkFPMzlGVEs5QjlWJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

By any chance, it is a possibility to adapt your serial for a USB version too or not ? Because I really need to use the product above.

Thank you in advance.
Have a nice day.

Do you mean USB HID?
USB HID is different from the COM port or virtual com port. They use different win32 APIs. The serial port is just a COM port on Windows.
