# NFC SmartPoster example

Demonstration of possible usage of the the `NFCController` class.

The application creates a smart poster record and sends it when a connected peer requests it.
The smart poster record generated contains:
- A URI: https://www.mbed.com
- A title: "mbed website"
- An action: `EXECUTE` which asks the peer to open the URI.

# Running the application

## Requirements

Verification of the sample application can be seen on any a smartphone with an NFC reader. After running you will be able to read the tag with an NFC tag reader application.

This example is known to work on boards connected to a PN512 shield.

**Wirring diagram for NFC Explorer with PN512**

If using the Raspbery Pi explorer (PN512) board, use this pinout mapping diagram to connect the shield to the reference target. In this case a ST NucleoF401RE pinout is shown.
