Reading ID Cards from the Web with a Localhost Agent

Browsers cannot access smart card readers directly. A workable approach is to write a small agent that opens a port on localhost and let the web page call it. This article covers secure contexts, CORS preflight, port conflicts with other agents, PC/SC in SHARED mode, decoding TIS-620 manually, and the day antivirus flagged the program as a backdoor.
