If you want to send card data through a device, I don't think ruby will do that for you, instead you have to delegate this to browser, because it must be a client process and ruby works from server side.
-- Everything that you have to do by client side, you should do through browser API and to use ruby (or any backend lang) to process these data.

I have a Ruby on Rails web app via which I want to access my smart card reader connected to my PC via a USB.
The idea is to press a button in the web app to initiate read action in the card reader.[I have a ruby script to read the data serially].I however want to extend the functionality to the web app,i.e. when the user clicks the read button on the webapp the card details are read via the card reader and displayed in the web page(Ruby on Rails web app). I am not sure on how to go about it. These are some of the "sources" that I have encountered online which might be the possible way:
WebUSB API
chrome.usb
libusbAnyone who has previously done the same please guide me on how to go about it.
