This example will attempt to mimic an ISO14443A smart card
and retrieve some basic information from a PoS or terminal,
this can be used to establish a communication process.
Note that you need the baud rate to be 115200 because we need to print
out the data and read from the card at the same time!
This is an example sketch for the Adafruit PN532 NFC/RFID breakout boards
This library works with the Adafruit NFC breakout

Check out the links above for our tutorials and wiring diagrams
These chips use SPI or I2C to communicate.
