That is correct, but also you will need additional pin on sim card connected to nfc chip (sim card as SE is the only option left). And driver support for that.

Just like I said. Please read the whole message (after the PN544 part). :D

How would one access this protocol support, does the OS already support it, is it merely disabled?

the device has the needed additional hardware support for it (something I don't know if the C7 or the N9 really have), and there is the needed software support for that in the firmware, you could use a secure element within the UICC..

This whole paragraph is ambiguous to me.
Additional hw support for what? What's the UICC?
Can you please clarify what you're saying here.

So the lack of an eSE in the device doesn't pose any problem... as long as the SWP support is in place.

This is similar to what I've always hoped for, which is;
A SE can be added via some other means, that SE has NFC/SWP integrated, & that somehow the OS can hook into that.
But what you're suggesting it seems, is that one just adds a SE*, & the SWP/NFC built into the N9's NFC chipset is used.
Please correct me if I'm misunderstanding you.

*via SIM most likely but possibly other options.

Thanks I'll read that when I've got a minute.

Please have a look at this picture of the internals of the N9:

The NFC controller is the chip labelled NXP 44501 at the top on the right side.

About the software support the N9 firmware may have for the SWP protocol, I just have no idea.

SWP is a protocol for communicating the NFC controller with the existing SE (secure elements). Therefore, a physical path between them must exist. Does such routing exist in the N9? Again, I have no idea.

By the way, UICC stands for Universal Integrated Circuit Card, most commonly known as SIM card. Any SE you wanted to use with the N9 should be within the UICC, as there is no eSE (embedded secure element) in the handset itself.

Exactly. If the SWP support is in place, just put a SWP compatible UICC card in your phone and that's it.

Re: NFC Payments N9

In the Netherlands payment in parking garage's and in canteens of sports facilities is normal, however it is used with 'tags' or an NFC sticker on the mobile phone :(
No NFC chips in the phone are used as of now, but we are promised that it will be here this year and widely available.

Cool, hopefully more is revealed soon.

Re: NFC Payments N9

I would like to know if N9 is capable on using NFC on RFID 125 kHz frequency?
Info about nxp pn544 http://www.nxp.com/documents/leaflet/75016890.pdf

NFC (not just the N9, but any NFC device) only operates at 13.56 Mhz.

Re: NFC Payments N9

We´re about to have NFC payments in Brazil.

Take a look at this video (it´s in portuguese, but I think you can get the point).
