Though I'm unsure of what uses an NFC would have with such a large device as the Jetstream, it would have been an interesting hardware spec to have added in, huh?
I read NFC tags all the time with my EVO LTE thanks to tagsfordroids. (get in and out of the car, and a separate tag for enabling gps and opening maps in the car(handsfree!))
What would be some uses for NFC with tablets?
I suppose the Nexus 7 tablet has it...?

Hi guys,
Yesterday I was thinking about how to enable the NFC sgs2 not have this technology, so I thought that using bluetooth or wifi direct you might also enable nfc
Android is not a developer so I need someone who can create a program that "hijack"the signals that are transmitted via the nfc nfc chip to an external device via bluetooth or wifi direct, then I did this I will create a hardware device composed of the NFC chip and a receiver / transmitter bluetooth or wifi direct to hide behind the battery, you will be able to receive the signal and then sending it to the NFC chip.
Does anyone know how to help me?, I am completely new in the Android paronama.
I think nfc is a magnetic signal, very different from BT, or wifi, so I think this idea would take a whole notha level of brilliance to actual make happen

It should be possible in the future to use NFC with an SD-Card that has NFC integrated. I think a diy is fun, but possible more expensive due to your bt solution.
are we sure nfc is not inside first sgs2 ? how to check ? Maybe it can be activated in few times.....
NFC is very similar to wifi, and also by bluetooth it to communicate using a wireless frequency.
however, what is the story of the NFC in the sd card?
I really don't think its worth the effort involved. Reminds me of someone I know who spent thousands trying to make his bmw 318 into an m3. When he finished, it looked ****e, didn't work properly and could have bought an actual M3 with the money he spent. Sorry to put a downer on this.
There is no NFC in the Sgs2. Als new Sgs2 has been announced with tiny improvements and NFC os included.

You would be better with SIM based NFC tbh... You can't just randomly say "let's use wifi/bluetooth instead of NFC, as they both work on radio waves of some sort"
I still want to use the wifi / bluetooth nfc only to transfer the signal to an external hardware that transmits, via the receiver wifi / bluetooth, nfc signal to a transmitter.
the idea and the hardware is easy to do, but the software ... I do not know, but I think it's tough.
at least someone can tell me of the nfc in the SD card?
Just buy an nfc enabled phone if you want it that badly. Trust me, trying to do a DIY job will bea waste of your time and money and will all end in tears. LOL.
i'm not sure if it's asking this'd be dumb but how would i understand if i got nfc şn my phone? i bought my sgs2 yesterday but it's still grey market here in Turkey so i can't be sure if i got nfc or not..
NFC sticker can make SGS2 NFC enabled..

Wow, it's amazing how many people post without reading the first post where OP clearly states he wants to create a device that reads NFC and then transmits it to the phone via bluetooth or wifi :

Also, using an NFC sticker is not the same : It will enable you to use your phone as a payment or transport card, but it won't allow your phone to actually READ NFC tags and display some information, nor REWRITE NFC tags.
Anyway, I think it's a good idea but probably not worth your time and money with NFC enabled Galaxy S2 coming in a few weeks or months. Besides, even if my SGS2 doesn't have NFC, I'll probably have a new phone in 18 months or so when NFC becomes really useful.

Agreed here. Surely the most used function of NFC will be for payments until other phones catch up, and this is accomplished by a sticker anyway?
I'm all for modding and hacking, obviously, but I feel that it may just be needless in this case...

Hehehe.
Anyone got the userspace nfc stuff, either from korean model, or the nexus s? That chip is the same as in the N S
not every model have the NFC chip on them samsung did say that some already do have it and they just need a software upgrade to enable it but i know none of the UK models have a NFC chip. Samsung also said that the one with it are slightly thicker phones than the ones with out it...
microsd nfc cards
Didn't someone mention here that Samsung had stated NFC was on the battery in enabled models.
Could it be one of the options here http://smartsim.info/products.html
Item 2 - special battery combined with carrier provided sim could mean even reader mode is possible retrospectively for a fairly nominal charge
At least for normal batteries. I now have 2 std 1650 batteries, a mugen 3200 and eyes on the new 2000 mAh options . Yikes.
Great News for the normal SGS 2 Users.
The BCM4330 has a number of listed features that our SGS2s do not appear to have. For instance, the chip in question has listed support for Bluetooth 4.0+HS (so, I assume the Bluetooth low power standard) and FM Transmission/Receive, however all sources state that the SGS2 only supports up to Bluetooth 3.0, does not have Bluetooth high speed (virtually the same as Wifi direct, I'm told, but may not have the same level of uptake) and there are no references to FM transmission.
Without relevant APIs or sources I assume none of these unused features can be utilised. Is it a possibility that Samsung removed some components of the chip to reduce bulk?
What's confused me about this entire situation is that the original Galaxy S and the iPhone4 feature this same chipset, but there's not even a mention of Bluetooth3.0 even though they appear to support it . . . weird. Perhaps I've completely failed to understand the nature of these chipsets, but if I'm not being completely stupid then it'd be nice to explore how one could fiddle with our precious phones to extend its capabilities.

Example:
Back then, at MWC 10, Samsung introduced the Samsung Omnia HD (i8910) which has alot of things AND an FM transmitter, when the device was actually launch, it didn't have the FM transmitter, modders and coders saw & knew that this device have the component, even proved with a secret code and an app they build, but no one has ever managed to get it to work.
So far of being a costumer at Samsung corp. I noticed 2 mistakes that they are repeating:
1. Samsung can't manage to get solid 30fps at 720p devices and 1080p.
2. Samsung rls products with an FM transmitter but they never support it and doing everything that we won't manage to get it work.
The fact that this chip is capable of performing all those tasks does not mean it is capable of doing all those task simultaneously. There might be some hardware challenges/contradictions between the different roles.
For instance, bluetooth 4.0 requires filtering above 3GHz of more than 10dB, while at the same time the chip is capable of Wifi on 5GHz; both are supposed to be on the same antenna so either you can not use the chip for Bluetooth 4.0 AND wifi 5GHz or you have to use some very complicated filter depending on which mode you're using. If they have not supplied this filter inside the chip then it becomes a bit complicated to use both modes.
The FM transceiver could very well be connected to the same internal power amplifiers as wifi but a wifi antenna does not look like an FM antenna.
It is not always possible (actually seldom) to use all the specifications of a chip at the same time with the same hardware setup. (Though often the user won't notice because it is not able to check the specification, like ultra low power and high speed often conflict.)
The features you mention are integrated into the chip itself, so it's not possible to "offload" them. However, they may leave out necessary off-chip components and/or enabling software.
For example, FM is popular in Korea. Many Samsung models targeted to the Korean Market include FM capability. It requires extra hardware though, including a rather primitive looking FM antenna. The corresponding models for other parts of the world leave this out. I presume Samsung doesn't see the popularity of FM in other parts of the world to be enough to make up for the extra cost in the handset.
Drivers and such require work, too. So while the chip may support the capability, they may postpone the software development for various reasons. If the hardware support is fully intact, it might be possible to make something work, but it could require some very deep hacking.
requist's response is interesting and seems like a possibility, although a quick reading of the Broadcom product page seems to suggest they've accounted for mixing capabilities in the chip design. Hard to tell without more detailed info.

That does not solve hardware conflicts.
I am wondering if our device can read RF ID tags as they are used in animals when they are microchipped.
From some of the readers that are offered for sale to vets I have gathered they are being described 134.2KHz Half and Full Duplex tags, or HDX and FDX.
Does anyone know?

Everything I've read says no. NFC works at 13.56 Mhz and it seems highly unlikely that they would build the NFC radio to be capable of handling the lower frequency rfid chips as well.
Just to add. In the past using ics with the patch to enable nfc I did actually try it on a known working animal rfid tag and it did not register at all on my phone or any app i tried with to read tags. I verified the tag did work with the rear ahead of time and it was not installed in skin when i read it but rather still in the original packaging so interference should have been minimal.
Hi guys,
i found this in an article:
http://news.cnet.com/8301-1035_3-57389687-94/the-power-of-bluetooth-4.0-itll-change-your-life/
One-tap hookup
Another convenience newer forms of Bluetooth brings is compatibility with NFC chips. Both Bluetooth versions 3.0 and 4.0 can talk to NFC hardware in phones and laptops to make pairing a simple process of tapping the two devices together. So you can imagine configuring Wi-Fi settings on mobile gadgets just by resting them on NFC equipped routers or hooking up headsets with tablets and phones in the same manner. For example, Motorola's new Elite Sliver headset already has this NFC pairing ability. Frankly the idea setting up a gadget this fast gives me goosebumps.
What Exactly does this mean??? can we pair our desire x with NFC phones??
Or am i totally in the wrong direction??

for pairing with nfc devices you need a NFC sensor in the phone which can interact with NFC enables devices like portable speakers or laptops to be put in simple words NFC just removes the troublesome pairing problems in bluetooth or wifi and helps in data transfer via bluetooth or wifi which ever is available and is faster (in most cases its just wifi but relating to this article and practical life Bluetooth also comes in the picture)
hope this clarifies your doubt
I already know what you said. I'm just trying to understand the article. He says Bluetooth 4 can pair with NFC. How ?

Bluetooth devices with A2DP profiles can pair with nfc devices which is seen Bluetooth headsets and speakers usually which is missing in our dx so technically you can't connect with nfc
Edit - tried to pair with my friends xperia p with nfc with A2DP profile from an app failed
I think Bluetooth is just used as a way to trust the NFC partner.

is there any way to add NFC on the xiaomi redmi 5 plus?
I recently upgraded from Samsung galaxy s6 and I missed the NFC
is there anyway with soldering and mods to do something or not?
NFC is not a software feature that could just be enabled, rather a hardware dependent option that requires a nfc receiver and beamer at the back of device, generally present in the back battery cover
So if your device is nfc enabled i.e has a NFC chip then it can interact with other devices and read/write nfc tags etc , otherwise you're out of luck and there's nothing you can do
Nfc dead trend
Is there anything like NFC dongle or something that can be attached to my mobile that works exactly like nfc in mobile ?
I'm pretty sure this phone doesn't have NFC, since the people in China prefer QR Codes in apps like WeChat over Google Wallet.
Unless you want to do stuff with NFC tags or use it to pay without your credit card, it's not really that much of a loss.
