Extending Badger 2040 with NFC

Hello everybody,

I would like to extend the Badger 2040 with NFC reader/writer/emulator, so I can print on the display data read through this interface.
Would this device fit? Gravity: UART & I2C NFC Module - DFRobot
How would that work?

Many thanks :)

I don’t have any personal experience, but given that it works with I2C it should at least be electrically compatible with the Badger (you can connect via the QT/ST connector if you have the right cables or solder directly to the pads on the side). The board you’re pointing to there uses the PN532 controller which appears to be at least compatible with CircuitPython (according to this article)
