Abstract

This disclosure relates to systems with multiple NFC front ends and at least one shared controller. One disclosed system includes a first discrete device having a first near field communication (NFC) controller, a second discrete device having a second NFC controller, a communicative connection between the first discrete device and the second discrete device, and a system controller located on the first discrete device. The system controller is communicatively connected to the first NFC controller. The system controller is connected to the second NFC controller via the communicative connection. In specific approaches, the second discrete device can include a display which is also controlled by the system controller, and the system controller is NCI compliant and application aware. In specific approaches, the system controller can control the second NFC controller based on the content concurrently being provided to the display.

Dependent claims

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.
