Android NFC access card reader demo

What if your company/client has rolled out an access card system… You know, the sort that you swipe your card across a reader, it beeps green and doors open… and you’d like the same functionality for your mobile apps? Something like, the user swipes their card, and an app opens, detects the user, and displays the appropriate data according to who the user is. By extension, you can build an app that requires two factor authentication, e.g. a PIN number (something you know), and the access card (something you have). This proof of concept is something I built to show off that android phones and apps can actually support such scenarios through NFC.
