| 8 | This example will attempt to mimic an ISO14443A smart card |
| 9 | and retrieve some basic information from a PoS or terminal, |
| 10 | this can be used to establish a communication process. |
| 11 | |
| 12 | Note that you need the baud rate to be 115200 because we need to print |
| 13 | out the data and read from the card at the same time! |
| 14 | |
| 15 | This is an example sketch for the Adafruit PN532 NFC/RFID breakout boards |
| 16 | This library works with the Adafruit NFC breakout |

| 19 | Check out the links above for our tutorials and wiring diagrams |
| 20 | These chips use SPI or I2C to communicate. |
