1. A system comprising:
a first discrete device having a first near field communication controller;
a second discrete device having a second near field communication controller and a display, wherein the second discrete device is connected to the first discrete device through a communicative connection;
a system controller located on the first discrete device and communicatively connected to: (i) the first near field communication controller; and (ii) the second near field communication controller via the communicative connection;
a first NFC library stored on the first discrete device;
a second NFC library stored on the first discrete device;
wherein the system controller controls the first near field communication controller and the second near field communication controller;
wherein the system controller uses the first NFC library to interface with the first near field communication controller;
wherein the system controller uses the second NFC library to interface with the second near field communication controller; and
wherein the system controller controls the second near field communication controller based on a content to be displayed on the display.
