Arduino library for reading ISO15693 RFID tags using the PN5180 NFC Module from NXP Semiconductors

## Introduction
This library was created to read the UID of tags presented to a PN5180 RFID reader, as below:

The PN5180 implements the [ISO15693 "vicinity" protocol](https://en.wikipedia.org/wiki/ISO/IEC_15693), which typically enables tags to be read at a distance of ~20cm. This is a significant improvement on the common MFRC522 boards that use the [ISO14443 "proximity" protocol](https://en.wikipedia.org/wiki/ISO/IEC_14443) instead, which has a typical read distance of only a few centimetres.
