[Pcsclite-muscle] Proposal for a Web API for smart cards

Hi Ludovic,

The idea is to enable applications that rely specifically on PC/SC to
be delivered as web apps instead of native apps.

The AusweisApp2[1] for instance uses APDUs and sends control commands
to tell the reader device to establish a PACE channel with the card.
It also sends another control command to detect if the reader at hand
declares PACE support in the first place, because otherwise it
implements PACE directly in the host. And then you have the browser
talking to this app. That API would enable AusweisApp2 to be a web app
for instance.

Another example is remote access (or "remote desktop") applications.
They can enable the remote system, and the applications in that remote
system, to transparently access the card reader in the computer that
is running that remote access app. That also requires PC/SC API level.

Or a web-based kiosk with a card reader that reads RFID tags/badges
and changes its Web UI accordingly.
