So would this nfc really work?

In theory, sure. It's along the same lines as SDHC cards that give Wi-Fi ability. The real issue is whether or not it's worth it to forgo the extra storage space of a memory card in favor of a NFC capability.
The concept of NFC is really cool, but isn't there yet in terms of practicality. I only use 1 credit card so, for me, having to use my phone to do transactions will more than likely take more time than just using my credit card. There are security benefits to NFC as thieves won't be able to steal information from the magnetic strip.

I actually am worried this would make things less secure than currently using your credit card.

Here is what I found on there site
Will I lose data on my original microSD?
No. The great thing about moneto is the fact that the microSD doubles as a storage source on non-iPhone smartphones. If you have any data or media, such as application folders, music, videos, or pictures on your microSD that you’d like to keep you can easily transfer that content to the moneto microSD.
* * Transferring data from my microSD to my moneto microSD
Load your microSD onto your computer. You can do this by using a microSD to USB converter, a microSD to SD card converter with an onboard SD slot, or by leaving your microSD in your phone and connecting your phone to your computer via USB cable.
Copy all desired files from your microSD card to the new folder. Simply drag and drop the files or folders you wish to transfer
Right click your microSD card and select “Eject” to safely remove it
Insert the second microSD card as you did in step 1
Copy the files you moved in step two and paste them in the moneto microSD, eject the drive to safely remove the card. Removing the microSD without ejecting on your computer or unmounting on your phone can damage any data stored on the card.

My thoughts on it being less secure would be if someone has a receiver for NFC, they could access your chip. There was a news story here in Denver, I don't remember the station, where they went yo the airport with said receiver and started pulling up information from people with the NFC credit cards. I have no idea if that would be an issue on phones, as I have not done any research on it, so it may not be an issue...

You have to actually load an app and do an authorization in order to make a payment with a wallet through NFC.

I am trying to think about the hacking possibilities. Also when you think about credit card theft, cell phone theft is also pretty high. For example, if you have an NFC sd card, and your phone gets stolen, how easy would it be to hack in and get the pin and have access to everything?
I haven't learned enough about it though, I could possibly be mistaken/misunderstanding/paranoid.

How would you get the Google wallet app on your phone if u get this? I love Google wallet and use it all the time withmy nexus.

I believe it has nothing to do with google wallet. You have to download their own app in the market

That's more likely with RFID chips (the kind new passports have), not NFC. NFC has a very short range (literally, a few cm's) and as another person mentioned, you need to initiate a transaction for it to even show up. The only way they'd be able to do that would be to try and hijack the payment terminal itself since the range is so short. And even then, I'd imagine someone would notice if the card didn't seem like it was going through, but the customer was showing that they paid or it looked like two charges were trying to be made.
Security wise, NFC shows a lot more promise than RFID. It's really going to come down to how fast it expands (currently only uses MasterCard PayPass system and not all stores have those) and whether or not it's more convenient to use compared to traditional payment methods.

NFC - only active when phone is on?

today my nfc tags arrived and i intend to use some of them to activate different profiles.
e.g. one tag is in my car - on 1st touch it turns wifi off, bt on and brightness to 100%, 2nd touch wifi on, bt off and brightness to "auto"
so, the only problem i have... nfc on my hox only works when the phone is turned on and unlocked. simply turn on the screen is not enough, it must be unlocked.
so is there any way to use nfc while the phone is off? otherwise nfc seems useless to me. iirc the nexus s recognized nfc tags even when it was turned off.
someone with an idea?

I'd say its either a bug, or security feature, most likely the latter
Reason being I think because of the whole NFC wallet thing, you wouldn't want somebody to be able to take your money just by getting close to you for instance

It's a change introduced in ICS for security, the phone must be unlocked to use NFC.
I'm not aware of a way to bypass it. I thought a solution on my Galaxy Nexus would be to use tasker and widget locker but couldn't quite get it to work - I might have another look at it.

a reasonable explanation, nevertheless using nfc for changing profiles it isn't very convenient if i have to turn the phone on and unlock the screen.

I dont know where you got that from but i have to disagree with you. On my Galaxy Nexus the NFC works even when the phone is locked. Sometimes i put my GN on top of my wallet and it scans my credit cards.

Easily share stuff from one phone to another nfc enabled phone.
Use it to scan nfc tags that has been programmed to do something specific to your phone.
Quickly pair your phone to an NFC enabled bluetooth speaker. (I think Nokia has one speaker with NFC).
Wireless payments (google wallet).
Im sure there are more...

Strange it doesn't work on mine, or at least it didn't last time I tried it (maybe on 4.0.2). I'll have another look when I get back tonight.
Edit...My GN definitely doesn't read tags when when the screen is off/phone is locked. It was the same with my Nexus S once I switched from GB to ICS.
What rom are you running on your GN?

NFC on Non NFC phone

I was wondering if you can put in NFC into your phone like open it up and install the chip or whatever. Or like be able to plug it on to your phone thru the charger port. I also heard that SD-cards that can connect to wifi can that apply with NFC. if my question is stupid and ignorant feel free to say so. I dont want to impose or be a stupid noob.
Thank you.
I have a Inspire 4g (rooted)
P.s I think this is the wrong thread, I AM SOOOOO SORRY IF IT IS.
I dont usually post stuff.

No, you can't. There are some memory cards with integrated NFC, but they're very low storage capacity (1 or 2GB).

There are also NFC SIM cards... But I don't think they are commercially available. Yet.

IT will be possible..

I think they have magnets abouts the size of a credit card or smaller that will stick to the back of your phone.
I havent had a device with NFC yet, but it may be a must-have for my next device.

you wont be able to install it via the micro usb or via the microchip on the pcb but the memory cards have a look here http://www.moneto.me/faq

I think that UK is going to accelerate the implantation on the occasion of the Olympics.
Surely, a requirement for my next device will be leading NFC.

Hardware issue , i dont think this possible.

This is a cool feature but as a must-have for a phone? I don't know...

NFC is Near Field Communication right?
Thought it could be used for bluetooth alternative also.
(like phone to phone etc....)
Would love to have, but Desire S doesnt have it.

just wondering, whats the good side of NFC? i only see that as a battery drainer..

Even if you managed to add an NFC radio to your phone, you won't get it to work with google wallet due to the lack of a so called "secure element" which secures the transactions.

http://translate.google.com/transla...overca-presenta-in-italia-la-sua-sim-nfc-347/
They're going to implement that into SIM cards, many (most?) phones have one. Don't know about Google compatibility though, they talk about Mastercard standards.

After reading about NFC sim cards a few months ago I asked T mobile(UK) if they are going to be getting NFC sim cards any time soon, and the guy behind the till looked at me as if I was on crack

IMHO, the best implementation for this on a phone that does not have NFC pre-installed would be from the battery. It requires a hard connection to the circuitry to be powered...the easiest way to do that would be with an nfc-capable battery. The only pitfalls to this would be expensive replacements, slightly decreased battery life and possibly 1-2mm extra thickness to the battery itself. I think a ton of people would gladly take those small caveats to have NFC on a phone that shouldn't.

tjhe battery shopuld be the problem.. but after looking at this >> http://www.gsmarena.com/compare.php3?idPhone1=4576&idPhone2=4695
the question is, why nokia use same battery for a non nfc phone and a nfc phone.. (ps:NFC chip weight is at 3.5 Gram?)

so i think that the third party companies should work on this for say like extended batteries... and provide a market link or add a market app that would give the nfc chip in the battery to work as an example or a dev do so to make the google wallet to think it is a valid phone with use and nfc chip...

You can't use Google Wallet with phones that don't have it built in period. There's more than the NFC. There's a chip called a Secure Element that's separate and stores all of the information for cards, etc. The phone either comes with it or it doesn't.
Also for phones with batteries that have an NFC chip in them, that's just an antenna for the chip inside the phone. It does nothing in a non-NFC phone.

External NFC readers

I found out my phone doesn't have NFC capabilities (Samsung Galaxy S2) and I hear there are external readers available that use the sim card slot or SD card slot. I was wondering if anyone has tried them and if there are any limitations compared to integrated NFC on a standard mobile phone.
I'm doing a project on NFC and its basically buy one of these or get my hands on a Nexus S.

Careful there buddy, your confusing things. What is it you want to do? Do you want to use your phone like a card, or do you want to read other cards? Either way, if your phone does not have any nfc capabilities, then that means you have neither the nfc antenna, nor the nfc controller, nor a secure element. The only way to get NFC capability to a non capable phone would be to use an sd card that brings all the components I just mentioned with it. I don't know of any company to currently sell that.
But before you go running after a new phone, be warned, if your project has anything to do with using your phone as a card, just let it go. Not worth buying a phone just for that as your project may probably fail.

My project deals with reading data off a card, altering the data and either writing the new data to the card or emulating it.
Are you saying this isn't possible with the SD readers or current phones ?

You could try to find a NFC-enabled battery for your S2.

Reading and writing to a card is possible as long as it complies to the nfc forum specifications. That means your phone can read most of the NFC Forum Tags and cards that generally comply to iso 14443 A or B. Some of the phones can also write Mifare Classic cards. It basicly depends on the NFC controller inside your smartphone. Smartphones that use NXP's PN544 chip for example have the capability to read and write them.
As for the SD, this is rather an open case. Adding NFC functionality to a non capable phone is not that easy to acchieve. In most cases you ned to equip your phone with secure element, nfc controller and nfc antenna. In order to do so you need hardware that basicly provides all of that. I read about some microSD cards that may bring all the components, but I haven't seen anyone sell them. It's definitly easier to buy a new phone that has all the capabilities you need.
Emulating a card is currently a dead end for third party devs. Unless you can talk to one of the big players like MNOs, TSMs or handsetmanufacturer you will be out of luck. If you are ok with rooting your phone and loosing warranty etc. you can maybe get card emulation to work. An example for it to work would be the app simplytapp that is available only for users of the cyanogenmod 9.1 and 10.

Nfc key fob

Is it possible to use my phone as a key fob for my apartment complex? Or say my workplace?
I saw the big confirmed NFC list elsewhere, but was curious of anyone has tried or knows about this.
Thanks
Sent on the run. Band on the run.

This has been talked about before, no you cant, its not using the same technology. The easiest way to check this is to get the NFC reader for your phone and try to read whatever your trying to use, like a security card for the building, it will not read it and this will tell you its not the same. I had the same idea as at work I have a Prox II card to get in and around the building, tried to read it and it would not work, I checked the web and sure enough its not the same frequency or something along those lines. At this time its only good for paying at places that have the ability and messing with your own tags.

Where is the actual NFC device? Is it in the Battery?
Im curious if it's upgradable (aftermarket, of course) to add on more frequencies

For the S3 it is in the battery as you say. So an aftermarket battery will likely not have the NFC functionality in there that you would like.
