I'm in Japan again for a while. Hopefully today I can go and source some tiny NFC reader from Akihabara and then continue working on it this weekend (its a long weekend in Japan). I'll definitely post a video when i've made some more progress. I'll also update the github. But now that I've got this idea, I'm going to move the credential provider part of the service as a main part, rather than as a plugin so that it makes more sense to use this so suspend plugin processing (so that swiping a ring with an RDP credential prompt up doesnt lock your local machine instead of passing the login). Otherwise i'd have to make a more complex rules engine for processing plugins
i.e. you'd "activate" a plugin to run "only when the machine is logged in" and set the order that they ran and also make one be able to stop processing all of the others. and this might have to be registered on a "per ring" basis.
-> get list of plugins
-> get machine state (locked, unlocked, awaiting credential)
-> run plugins in order
-> check plugin result, and stop processing plugins if required
Its all doable. I'll work on it and post an update when i've made a decision for how I want to do things.
