I need to build a webform app that can generate cards for customers. Each card will have a unique QR code or barcode on it so customer can scan it to check-in and check-out when they come into the store. To generate QR code, I found this article on our website and I think it will help me with the “generating card” step:

So a new customer come in, we will enter customer’s info and save it to a SQL server DB, get the ID returned after inserted that record and use it to generate the QR code and print out the card.
My question is on the “reading card” step: let’s assume a customer has a card and they come to the store, what happened after they scanned it? I mean how the scanner works? People say that the scanner acts like a keyboard, is that true and how?
Basically I want to make the “scan action” to act like a button click event (or enter key pressed) so I can put my logic code in, something like this:
That’s it, I just want to save check-in and check-out time now. Is it possible and how to archive, what scanner should I buy?
