The card and id tag that come with the board use classic mifare technology. Wiring I'm going to use Arduino Nano for this example, you can use Arduino UNO and perhaps other Arduino's too. You can't use any pin for the module board, you need to verify your Arduino's pin map and map them accordingly, for example, you can only use SCK on pin D13. | |

Unfortunately, it chokes on "data" meeting a certain set of conditions and so I need to kick data like that from the list before running it. This is kind of hard to do... | |
