Introduction
Near Field Communications (NFC) is a contactless communication technology based upon the ISO 14443 standard. Being standards-based, NFC devices can easily interoperate with other contactless protocols including the highly popular Radio Frequency Identification (RFID) protocol.

The reader will detect the nearby presence of a tag device and then light an LED.
The reader will be controlled by a software package named libnfc and a Python program running on the RasPi. Be forewarned: a fairly involved development process is required to install the libnfc software. ...
