Appologies in advance if this is complete rubbish. From what I understand, NFC works by holding devices/cards that are NFC enabled close to a suitable paypoint. Some bank cards, eg Barclaycard already offer this service. From this, am I wrong in assuming that its not the hardware thats important, but moreso the acual chip on the card. If thats the case - is it down to the network operator to issue the modified chips/sims to slot into the phone to make it NFC enabled - OR do you actually need modified hardware on the phone? If you do need modified hardware, whats stopping anyone from opening a bank account that issues NFC credit/debit cards and simply cutting out the chip from the cards and putting that chip under the back cover of your phone (the chips from the cards would be pretty small and should easily fit under the cover in the battery region)? That way, you could still tap and pay with the back of the phone. Is that completely ridiculous?
NFC posts here show on sim .

I think the idea is that u can reprogram the chip if its hardwired into the phone or something..maybe look it up on Wikipedia or something.

thanks for replies. So, JJEgan, the nfc enabled phones are physically the same as 'non enabled' oness? Its just the SIM thats modified?
They are not the same.
The NFC chip in the the Nexus S can read, write, and emulate an NFC tag. It allows developers to use it for their apps.
I suspect that the NFC enabled sim cards only have an embedded NFC tag, which I don't think developers can access. It simply acts as a single purpose tag for payments for example, just like in some credit cards. It would not allow for read/writes, or for multi use emulation.

Orange demoed the SIM being used to read and write tags as well as making payments. The SIM is using technology from Gemalto to allow it. It's just a case of having the right app on the phone. I'm hoping someone with a GS2 will get ahold of one soon enough.

Yeah that is my understanding to, you can either have the phone with a built in chip. Or use an NFC enable micro sd card.
Both give you the same functionailty. The down side is the sd cards are probably small capacity in terms of gb for storage, and you would not be able to swap out the micro sd and still use nfc (if you are one of those that uses multiple sd cards for storage)
The micro sd route would be a good route for samsung to go, send a free one to all of those that purchased the launch model without nfc built in.
Not heard of the sim option. But I guess it would work in the same fashion as the sd card.

I don't think so. From what I gathered the NFC enabled SIM card can only be read by other devices, so it will be able to act as a contactless payment or transport card. BUT it won't enable your phone to read or write NFC tags, so you won't be able to tap nfc enabled ads to get information (like with QR code but without the camera), nor to create your own NFC tags with your phone.
Unless someone can point to the 13.56 mhz antenna, this phone won't be doing any read/writes.

The antenna is built into the microsd card

Reading around it does look like both the sd and sim options focus more on using nfc as a payment method, than on other uses for the tech.

True, but that antenna is just for the NFC tag in the SD card to be read by another device. There is no embedded antenna or NFC chip in the phone, nor the ability to add integrated NFC at a later date. The NFC abilities in Android can never be utilized without that.
You are correct that this limits the use to small payment or transit access. Might as well tape your Barclay credit card or Oyster card to the back of your phone, there will be no integration with apps.

Here in Sweden there is rumour that SGS2 I9100 will not have NFC at launch.
NFC will come later and the SGS2 without NFC cant upgrade to NFC.
For me it sounds like a totally stupid idea.
What do you think ?
Have you read anything about it in any other country ?

Well I don't know about Sweden but in Ireland, support for NFC is pretty scarce (read inexistent) so no harm really...
Same here...Just a few project and i think i have SGS3 before NFC is big here..
But i still hope NFC is in SGS2
I want the best heh

Here in Finland we hardly have color TV's, so the lack of NFC is not a problem.
Doesn't bother me much if they have NFC. In India there is no support what so ever and I think it will be years until it does.
Although I would still appreciate the technology within the phone. I travel a lot, and it would make it easier to conduct fast transactions.
Clove have confirmed (in the comments) that the UK version will have NFC:
http://blog.clove.co.uk/2011/04/14/...-confirmed-exynos-chip-quad-band-3g/#comments
No NFC would be a big deal for me -- sure, it's not popular yet, but getting phones with NFC on board will be key to making it popular in the future. Google are also pushing NFC heavily:
http://www.engadget.com/2011/04/14/google-expands-nfc-check-ins-clutters-more-restaurant-windows/
It doesn't really matter if you really need NFC you can buy one of these SD-cards http://www.nearfieldcommunicationsworld.com/2009/01/12/3485/tyfone-puts-nfc-into-microsd-cards/ they have built-in NFC
i find NFC totally useless at this point
i've had the Nexus S for aprox 6 mth already, and i still have not found a SINGLE place that will offer NFC anything,
i'll be happy to see an add via NFC, but not even so.
i'll say we'll need at least 2 more years before the public sector, and market includes more NFC stuff.
i'll be interested to use my phone to pay for items via NFC
but NONE store supports that yet.
again... NFC is too green, there is no market at all for it yet.
in 2 years time we'll probably be at SGS 3 or SGS 4 already
Agree, especially in locations that NFC requires data transfers, most stores wont be able to offer it in India. I could see some retailers doing it but it cannot be expected that EVERYONE will go crazy over NFC and buy a $700 device to utilize it.
In sweden Samsung has confirmed on facebook that SGS2 launch without NFC.
And that they will launch one version with NFC later.
--------------------------------------------------------------
I cant wait.
Lucky me that i live in north of sweden.
It will take years before NFC is here

It might be that for certain carriers branded S2 will be delivered w/o NFC since the carriers THEMSELVES integrate NFC on their SIM-Card.
So speaking about NFC or not NFC: this is a tiny chip with a value of 1-2 .- € !

NFC can be implemented via SIM card if the carrier wants to and also via SD card. Where the chip is located within the device is mostly meaningless.

The phone can read the sim/sd-card, thus the NFC chip on the card. As long as the phone is prepared (in terms of hardware) to read NFC chips from sim/sd-cards, I don't see any problems.
I'm not an expert but I think that technically it should be possible to put NFC chips in cards like sd or simcards.

I don't think so .. you would need a new interface for the cardreader .. maybe something like mhl for the usb-port (standart-micro-usb isnt able to put out video as hdmi does) and i don't think this will be integrated ..
NFC will be integrated into the phone .. or not
but for sure not in the sd/sim card
Edit: Ok maybe it could work, according to some pages i found on google .. but still appears weird to me
Hello,
I am a CIO of a train company, and I have two questions regarding NFC emulation on NFC smartphones and especially Galaxy SIII.
1/ we have electronic locks on our offices, using standard NFC Myfare tags (like in hotels) is it possible to put my Galaxy SIII on "myfare mode" in order to record it in the lock and use the phone as a key?
when you put the lock in learn mode, it is only waiting for tag to be presented and record it as a valid key.
2/ we are developping a new PDA to board people in our trains. The PDA will be equiped with a IR and NFC reader. the customers will be able to write the serial number of any compatible myfare card when he buy a ticket, and then board presenting the recorded NFC card.
we will allow transportation cards, or others, but is there any easy way to say to the customers where to find the unique NFC ID of his phone?
Thanks in advance for your help.

I have the same problematic. We have in our company contact-less RFID company cards. With them we can access to our buildings, pay the canteen, and a lot of other stuff. Those card are Mifare tags too.
We would like to try to emulate those cards with androids phones. It's seem it's not that easy. If you have any clue about how to do it, i'm interested
First of:
[Rant]
Is there actualy a diference inn Verizon, Sprint, T-Mobile, AT&T and so on and so that it is needed 5 sections (including this one) with a full sett of sub forums for each one?
The way I see it this only makes it harder for people to get answers for they questions as the all the SGS3 users dont nesecarely read the same section due to this. Thus making each thread read by far fewer ppl than what the potensal is.
[/Rant]
I am unsure if this is the correct subforum for my question so the mod's can feel free to move it if I have mis-posted it.
At work we got credit card size access and copy cards.
The SGSIII can read the cards fine with the NFC TagInfo app.
The way our cards work is that each card "is sending out" a static card number.
When I get the person that "makes" these cards to open up Notepad on her computer and put my card on a cardreader connected to her computer, a number is "writen" into notepad.
When she "makes" new cards she access our company-program and goes into personell, then new card, prints name and picture on a blank card and is then told to place the card onto the reader.
The number is then added to the personell info and the card is linked to the access of the doors and the persons print user.
If I could get my phone to "send" a static number I should be able to place my phone onto the reader and then my phone would be my access and print "card" so.. can this (the "sending" of a static number) be done?
I'll answer your rant. Are you aware that the international s3 is different from the American version? The international is a quad core, 1gb team phone, whereas the American is a dual core 2gb ram with lte phone. American carriers all have their own s3 version, Verizon for example has a locked bootloader. With these differences the roms and mods created only work for the specific type unless you want to risk bricking your device.
So yes it is very necessary to have different forums.

Omg. Ofc, why make it simple if one can make it complicated..
It amazes me that one would do something like this. One would beleve it would be alot to gain for the company by having just one of the model on the market, both from a production, service and support standpoint.
Anyways, cheers for the info, atleast then I learned that what I read in the other sections might not work, or be aplicable to my phone then.
With the recent update, is it possible that a new sim card (like maybe the one that works with Isis) would allow the tap to pay feature?
In order to use Google wallet, you need NFC, but not a different SIM card
Sent from my SCH-I545 using xda app-developers app
I was just chatting with Verizon, and asked why Google Wallet would not tap n pay, he said I needed a NFC Sim card. He is sending me one at no charge. What is the difference between the NFC sim and the NFC battery? Why was the S4 not shipped with a nfc sim? I am not even sure if this will work... will let you know.
Thanks! Keep us updated.
The SIM card that Verizon sends you is for their app that they use for mobile transactions, is is. You need a special SIM for that to work. For Google wallet, you don't need that. All you need is a NFL capable device and you are good to go!

As with past experiences with Big Red I am not surprised that the customer service rep has no clue as to the actual service they offer. I have installed the new Google Wallet on my S4, with the NFC battery that came with the phone ( maybe someone can explain to me what the battery has to do with NFC? ). But I dont see an option to use tap n pay. I am rooted with Safestrap, and was contemplating installing the mod for GW, but now I see it has been abandoned. If I am missing something, maybe someone could point me in the right direction? I will get the sim that I ordered when I return from vacation, but I doubt it will have any effect. Would there be any other benefit from using the different sim card?
P.S. I would like to see this NFL sim card...

Since you are rooted and have SS installed you can install a functional tap to pay by 2 different methods. I have provided links to both methods below. The older method appears to be more stable. Hope that helps.

I'm trying to work out exactly where the NFC chip is in the S6 Edge as it seems hit & miss when I try & pay for something using contactless in shops.
I don't know whether to hold the top part of the phone near the NFC-enabled Simcard to the contactless reader, or some other place?

Looking at tear down photos, it appears to be located next to the camera module, opposite of the flash. It is a gold square.

I just had a play around with an NFC tag and the most reliable place for it to be detected is in the middle somewhere between the samsung logo and the centre of the phone.
Thank you very much for your efforts in finding the location of the NFC chip.
So I just need to make sure I touch the NFC reader at roughly just above halfway in the centre?
