I would look over the discussion in
https://bugzilla.mozilla.org/show_bug.cgi?id=988781 regarding future SC
support via the WebCrypto JS APIs. I would hope that having a W3C spec
for a smartcard API would encourage a common, cross-browser way to do
this without plugins or addons.

Have you considered using a local web server? That way you can use any
native code you want, and it's a reasonably common approach.
On many platforms you can even use socket activation to avoid the need for
a always running server process.

Good morning.
I have a use-case which will be difficult to reproduce in the post-NPAPI
world:
The use-case is a Java/NPAPI applet which uses the javax.smartcardio
library to communicate with USB-connected contactless smartcard readers,
from a web-page. Extremely useful functionality for our customers.
Currently the applet will work in Firefox, Chrome and IE.
With the deprecation of NPAPI, we are looking into ways to continue
offering that functionality, and need to continue to target all three of
those browsers if possible.
For Chrome, I have looked into re-implementing the Java applet as a Chrome
App, or using NaCl/PPAPI etc. I have not found any equivalent technology
for Firefox as yet.
Chrome Apps can connect to USB ports via the chrome.usb API, but there is
currently no implementation of PC/SC for it (the smartcard access
specifications that javax.smartcardio is also built on). Due to time
constraints, re-implementing PC/SC ourselves is an option we would only
choose as a last resort. In any case, that would only solve the problem for
Chrome, not Firefox.
Unfortunately, no technology I have looked into so far to solve this
problem is able to offer the cross-browser support that Java/NPAPI enjoyed,
and has an available PC/SC library.
I flag this use-case for consideration in a future web-platform. I am sure
we are not the only company who have combined smartcard io functionality
with the web, and wish to continue doing so.
If anyone knows of any technology or open-source project which might be
useful for this situation, please let me know.
