This example will attempt to connect to an ISO14443A
|
|
card or tag and retrieve some basic information about it
|
|
that can be used to determine what type of card it is.
|
|
|
|
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

|
These chips use SPI or I2C to communicate.
