Great finding! I looked a bit into the software side of things. First off: There's a driver needed: https://github.com/torvalds/linux/bl.../nfc-pn544.txt

Now to the weird thing: The sysfs entry itself is a hint that there's a driver attached. Also there's /dev/pn544 which indicates that the driver is up&running but modinfo tells there's no driver and there's also no /sys/module/pn544. Lastly:

gunzip -c /proc/config.gz | grep NFC
# CONFIG_NFC is not set
CONFIG_NFC_PN547=y

So I really don't know if there's a driver.

Now I would love to install some userspace tool to test but which one does support that chip? nfc-tools don't: https://github.com/nfc-tools/libnfc/issues/374
