so, i had no idea about this until just now because i know barely anything about smart cards, but apparently you can insert pretty much any card with an RFID chip and it'll just work as a smart card. when you insert your smart card, it'll give you a new desktop session you can use normally, then you can remove the smart card and it'll go back to whatever desktop session was active before. then you can come back to it later and put the card in either the same sun ray or a different sun ray, and your desktop will be restored. this is apparently called "hotdesking" and it's actually awesome, this is super neat. the reader even lights up when you put a card in it!

...now i would gladly demonstrate this for yall, but i'm using my actual credit card as the smart card for this so i don't think that would be a great idea lmao
