Unfortunately as I don't have working APDU auth yet I can't test playing this script into a ring ;-(

See the installForLoad function in node-gp where we build an array of APDUs. This would be 99% of a cap to script tool.

Now i finally got node-gp working i could put some time into this. Don't know if i should make a pull request to node-gp with some kind of cap to script export method or start from scratch, what do you guys think?

I'm all for it. It sounds like a useful function to have albeit still dependent on authentication which will have to be dynamic.

In other news it would be great if anyone could give attention to the mobile phone as a PC reader endeavor. This idea overlaps because if we can create a link between Android NFC and "any computer" over webrtc for example (with peerjs and QR codes for pairing?) then we can feasibly allow remote (and thereby support desk friendly) ring admin. As well as removing the need for anyone to buy a dedicated NFC reader.
