I have a similar question. I have to carry an annoying little fob around all day to get into buildings and garages in my apartment complex. My hands are often full and I would rather swipe my NFC ring than drop everything and dig for my NFC fob/tag. If like to read my fob and wite the information to the ring. Is that possible/doable? I have an iPhone, so what I need is a reader/writer I can use with my Windows 10 PC. Any suggestions on the hardware to buy for this? Thanks!
