Websites have "NFC login" enabled pages, where you can go to the page, and it will wait until your phone is wiped over the NFC reader attached to your computer. On your phone, you have an app that you load up, choose the site you want to login to, and your are magically logged in. It's a secure method of logging in, and it would basically use a hidden input field that is populated with a random hash that is created when you select the site you want to log into that talks back to the site via an API and registers that has in the user database as a valid NFC login token.
