title: Unlocking computer with NFC-enabled phone
body: <p>I want to have an NFC sticker on my laptop/desktop which when swiped with my NFC phone will unlock my computer. If I don't have my phone with me, I can still login using my normal password. I so far bought some NFC stickers and installed <a href="https://play.google.com/store/apps/details?id=com.jwsoft.nfcactionlauncher" rel="nofollow">TagStand</a> on my phone which manages to post to a server that I control. I want to write some small piece of software that would listen to this server and unlock my computer if the server tells my computer to do so. I have not made the last part work as I don't know how to write such a software for either Mac or PC. Is it possible? If so, how?</p>
