Might be worth tearing open a Jolla 1 for comparison shots?

There's a thread with a teardown by der_pepe (edit: of the original Jolla) here [1]
He posted some pics of the interior here [2].
And here's the bit about NFC from the first post:
The Jolla Blog did a write-up of it (which was easier to find on Google)[3].
Edit: there's a few related threads TJC (regarding JollaC and NFC), the last of which from last month [4][5][6].

•The NFC controller it’s an PN544 (labeled as 44701) manufactured by NXP Semiconductors.
It supports read/write of ISO 14443–A, 14443-B, MIFARE, FeliCa and NFC Forum tags, and
it can emulate such devices. There’s a good chance it’s already hooked up into the I2C bus, so it
might be “hacked” and be used for something else than just reading TOHs

I'm an electronics noob ...
So, if there's a chip already there, NFC capability might be added by simply soldering an antenna to the contacts?

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

Well, CONFIG_NFC_PN547 is a tristate so you could just try compiling it and see what it writes to dmesg on insertion.
I admit it is odd that nfc is set off but the driver is included. No idea which one gets preceedence...

But we need CONFIG_NFC_PN544_I2C (which is hidden behind CONFIG_NFC), not CONFIG_NFC_PN547. I don't even know what CONFIG_NFC_PN547 is for (linux kernel driver database doesn't know that, too).
Did I say this is weird? ^^
//EDIT: While CONFIG_NFC_PN544_I2C is a tristate, too, http://releases.sailfishos.org/sources/ lags behind for months so no way to compile anything.

I don't know what you have on Jolla-C but this is valid & up-to-date with Jolla sbj1 kernel; https://github.com/KonstaT/sailfisho..._jolla_msm8930
I have used that repository for successiful builds on my device.

There are 3 soldering points with the tag NFC on it...
Interesting...
