I dont own any devices that can read/write NFC so that means I would be paying for this on top of something else that can do that rather than this plugging into PC and doing what I want. If they wont make a USB model, whats the cheapest NFC read/write device I can purchase for this? P.S. I would of emailed them myself but I cant find their customer support email anywhere on their site. Feel free to post it and I'll ask myself.
