NFC

The NFC class controls the onboard ST25R3916 NFC reader. It selects the I2C bus, pins, and frequency for the detected controller automatically and supports ISO14443 Type A tag detection, MIFARE Classic block access, and Type 2 page access.

The following controllers provide an onboard NFC reader:

Controller	NFC
PaperMono	✔
StackChan	✔

MicroPython Example

Detect a tag

This example detects a tag and prints its UID and resolved type name.

from hardware import NFC

nfc = NFC()
card = nfc.detect()
if card:
    print(card.uid_str, card.type_name)

API

NFC

class hardware.NFC

Create an NFC reader for the onboard ST25R3916. The reader selects the controller’s onboard NFC I2C bus, pins, and frequency; no bus or pin configuration is required.

Except for initialization, this class provides the same reader API as unit.nfc.NFCUnit, which documents the shared methods and returned driver.nfc.Card object.
