I have this client with a USB plug and play proximity RFID reader that reads input from a card-swipe. When I open an Excel sheet and swipe the cards, the unique card numbers are copied to the sheet. Example of swiping 2 different cards.

enter image description here

How best to capture the card numbers to a webforms website on the event a person swipes the card?

I have created a console application to test the data capture using LibUsbDotNet 2.2.29 using the code here: How to read from a USB RFID Reader with C#

Is there another way to do this?

    You can provide a textfield (or textblock for multiple ids) and a submit button. This button sends this form to your server. For "real time" processing (triggered by change event) you need JavaScript and an API Controller. – Michael Aug 10 '21 at 10:39
  • That is one sure way. – Kinyanjui Kamau Aug 10 '21 at 10:56
