I have tried to use NFC on my brand new Note 3 today (SM-N9005) with my Nexus 7 and nothing happens when I open a website and put the two back to back? Which is supposedly how it's meant to work. Am I doing something wrong? or is my N7 or N3 faulty?
Btw: I have no NFC tags to test with (There in the post)
Thanks
Bump, I need to know what i am doing wrong, They're both using android beam
Sometimes one of the devices have to be upside-down...not sure if that helps but when using NFC on a Galaxy Mega and Note 2 one of them needs to be upside down. Not sure why.

Check the inside of back cover , the NFC plate is missing , we only have connector but no plate.
Good Job Samsung.
In Note 3 NFC antenna is built in the battery. Mine N900 is working with one NFC tag I have.

The NFC coil is in the battery. The connectors are for wireless charging coil.

I'm not 100% sure my NFC is working. Only was able to use it occasionally when Google Wallet wanted to work on some vending machines at work on my Note2 and GS3. Now when I have NFC enabled and hold in front of the reader nothing happens. Going to order some tectiles with my 50% off coupon and see if they work or if it's the vending machine.
Hi. I have try to connect my Samsung Galaxy Note 3 to NFC Sony XB10 speaker but it cannot be undone. What do I need to do.
99% of batteries bought on internet do not have NFC, so if you need new battery, beware

Hi all does the note 2 support inductive charging or do you have to replace the back? Its just I notice there is something in the back cover and i hear this is NFC for payments I was just wondering if it was also capable of inductive charging out of the box or if it has to be adapted in some way.

Well it has the wireless chargimg tabs under the back cover like the s3 so im going to say yes

If it does support this, I wonder why Samsung hasn't mentioned it in their presentations or included it within the official specs? Hope it is possible though.

Soo... here is a picture of the back... and yeah... i also think they have at least integrated the connectors for wireless charging into my note 2 xD

Out of the box it does not support wireless charging. I suspect it could be modified to use a Palm inductive charger though. I've been messing with my Note 2 and a Palm Pre inductive charger for the last half hour or so. The PCB of the Pre back cover fits into the little groove next to the micro SD slot (I had to cut a small part of the PCB off - see the red circle in the last image) and the coil/magnet cluster fits very easily between the back cover and the battery. Visually/tactilely it's pretty much impossible to detect when they've been put in there.
Unfortunately, I've never modded a device to use inductive charging before so I'm a little hesitant to proceed.
wow... that looks very good ...
Hmmm but without a technical background I would not risk that... you have at least to measure all that stuff ...

i would rather not to do it, i think note 2 is the ame as Galaxy s3, they have the capability you just need to wait for the battery cover replacement sold. or you can take buy one fro S3 and rip out whatever in that back cover (coil) put it in your note 2 back cover. http://www.androidauthority.com/wir...samsung-galaxy-s3-hits-verizon-stores-105433/
Its all just my theory though.... for me better just wait rather risking my gorgeous note 2 which is note yet in my hand right now....
Hello guys,
Former Palmer/webOS user here. Actually, toying with the inductive back of Palm Pre & Touchstone charger, is not that risky nor difficult, not at all. I've tested it as a kind of proof of concept, with my SGS 2 - just put the coils/PCB assembly at the back of phone cover, and soldered two wires to the coils's output contacts. These two wires, I just ran to the micro USB plug. When I've connected that plug to the phone's micro USB port and put the phone on the Touchstone charger, it starts charging - that's all. Coil's integrated PCB sorts out things like converting AC/induction back to DC, 5V etc. What you are getting out of it, is your pure, standard, USB-compatible juice.
The only reason why I wasn't using it permanently, was that I didn't wan't to solder anything on my SGS 2's PCB (didn't feel like it is a smart idea, with it's tiny tracks and my soldering skills - or rather the lack of thereof). And having micro USB plug stuck in phone's bottom all the time, didn't appeal to me, somehow
But if the SGS3/Note2 already had the required contacts behind it's back cover, it will be a breeze DIY project. And one damn handy and cool-loking charger on your desk, believe me.
I'll try to post some photos of my POC setup later on.
Best regards!

I purchased a couple of kits - one was just the inductive charging module for the phone, which I installed and separately picked up a couple of charging bases; the other one was a complete kit.
This kit (not by this seller, but the photo is the same as the kit I purchased) is very elegant, thin, and easy to install. You can barely see the bulge in the back of the case. The only problem I have is that the magnets seem to be slightly too weak so the position is a bit inexact. I've added a couple of extra magnets but will end up replacing the originals with my slightly-stronger replacements in the end I suspect. Overall this kit, although expensive on Ebay does the job and looks good.
This charging module was easy to install but the one I received had the polarity of the charging pins reversed so I had to make a modification to get it working. Here is a post of my preliminary mod to get it working; since that post I've done some clean-up but the one linked above thinner so I'm using it as my primary right now.
Maybe this help!!!

No unless that's what the empty cut-out on the door is for. I believe that mrm1 is correct the antenna for the nfc appears to be missing. Apologies been used to looking at my blackberry and that is where the antenna for nfc is. Quite sure the indent in the plastic is for a missing component though...

Nfc is there. That was similar in the S3 for the wireless charger which never came. Look up qi chargers on Amazon and you'll see what fits the slot.

The nfc is contained within the battery itself... Unlike every other phone on the market.
If u use a third party battery without nfc built in you lose the function altogether.

So I just bought this wireless charging dock last night: http://pages.ebay.com/link/?nav=item.view&id=400461623073
And thought that this is all I would need in order to charge my battery. However, Now I'm worried I will need a battery door. Does anyone know git certain whether or not I will need a different battery door to use wireless charging (currently using the one that came out of the box) if so, where would I be able to find one at? Thanks in advance!

Don't need to get a new battery door. That new Samsung door will actually be larger than the current one. Some/many cases won't fit.
Get this instead - wireless receiver that fits inside the stock battery door:

I pre-ordered the one for the S4, after it was written up on Engadget. It hasn't been released yet, apparently, so I'm still waiting.
Here's the Engadget article. Some good things said about it in the comments:

The order site says that it will ship by May 31:

Well, I just bought it. Will review it when I receive it on the 31st.

Samsung is terrible with the S4 accessories.. they release a new battery cover just to enable wireless charging.. ok fine.. but they release a stupid 70bux transparent flip cover that doesn't support wireless charging.. so basically i can never get wireless charging if i ever want to use their oem products or i need a special case if i want to use their oem wireless charging cover and fit?? real smart thinking.. guess i'll give this kit a try too
I thought it was the battery it self that has a coil in it for the NFC and that was for charging?
if not I have my palm pre still that has that wireless charging - could I take that battery cover apart and take that coil out and just attach it to the inside of the phone
I dont see anywhere where a battery cover with this built in will connect inside like it does on the palm pre, there arent any contacts that I can see that will go to the battery charting how would this work

Are you sure you are looking at a GS4?
There are 4 contacts. 2 to the left and 2 to the right of the flash. I think the left ones are for charging. I am basically ready to do what you said but need to figure out the polarity of these contacts.
There are other related threads but no responses yet...

To the guy worrying about the flip cover - there are tons of wireless charging inserts on eBay. You don't need the Samsung back, just get one of those things and stick it under the cover.

I'm using S3 kit and my friend is using notes2 kit from them, (receiver and charging pad) and have just ordered this receiver to use in S4
You can put a wireless charging receiver card inside your S4. Now it is a very pop way to charge your phone. If you need any technical help, please PM me.

I'm hoping yours worked. I've had a qi receiver in my S3 for about 6 months now. I pulled it out to see if it would work in my S4 and it doesn't quite fit. The pad would fit, but it lays over the sim card and mSdcard, which probably wouldn't be a big deal, but the problem is the two small brass contacts don't quite fit in the square charging holes on the s4, they're probably 0.25mm too large and slightly to far apart for the S4.
My S3 pad is about 6 months old though, so hopefully the newer s3 pads have been modified to work with both phones.
I love wireless charging though and just went ahead and ordered a qi pad for my s4 from the fastech link earlier in this thread.

Does the part you place in the phone get hot? Causing NFC or other issues?
hi does any one know why i cant use nfc when my qi receiver installed in my gs4 ,the nfc works perfectly with it out ,there is no aluminium foil around receiver cheers
The NFC antenna is in the battery, which the Qi charger probably overlays.
You need an external antenna that connects to the second pair of pins, I don't know where you can get one though.

I am purchasing a Galaxy S5 next week and I am looking at the wireless chargers as that is the main reason I am upgrading my S3 in the first place.

I kind of thought the hotspot would still be active, on the other note I had no idea the s3 was wireless charging. does that mean all it needs is a pad to lie it on? Not sure if I understand?

Yes it will. Or at least it does for me, so I don't see any reason it wouldn't for you as well. Your hotspot range may be reduced during wireless charging due to the RF interference, but if you had a strong signal before hand then you should be fine..
.
I've noticed no loss in wifi, hotspot or 3g performance while wireless charging, and the S3 and S5 can both use the same charging pad because they both QI compatible.
~7 dB effective attenuation when wirelessly charging my S5
Inferred from the increased 802.11N PER in an adjacent Asus RT-N66U router.
And consistent with decreased data throughput.
PER calculated from Ethereal capture.
Sample size = 5 x 10^3 packets
PER (packet error rate) is 1-(0.999^N), where N is the number of bits in the data packet
N = 32

None of the S5 variants that I have seen will wirelessly charge by simply placing them on a charger. You need to add two things - the charger and a coil. The coil is the part that is inside the phone, a sort of receiver. The coil looks like a thick sticker and you can either buy an optional battery cover from Samsung that has a coil in it.. or add a third party coil to the inside of your existing battery cover. This is in contrast to say a Nexus phone where the coil is not optional - it is already built into all of the Nexus phones.
So it's odd to say that you are upgrading from a S3 to a S5 because of wireless charging.. when both the S3 and S5 need to have the same components added to add wireless charging. You seem to think that the coil is standard on S5's and it isn't.
Note that the optional Samsung wireless battery cover is thicker than the standard battery cover, which means that some cases will no longer fit your phone. And if you add a coil to the inside of the standard S5 battery cover, you need to choose a coil that is thin or you may displace the battery cover and lose the watertight seal.

Thanks for straightening that out for me. Now I understand. Yes I am upgrading from a s3. I knew nothing about wireless charging until recently. Guess I need to get my nose into these boards more often. I am a road warrior and ran into usb port issues on my s3 in Denver a few months ago. I panic because I couldn't charge my phone, so I went to the closest 3rd party phone repair store and they sold me an extra battery and a external charger. That worked great but the fact that I had to swap batteries 2-3 times a day, left my phone without a case, and you know what happened next. So since my upgrade is tomorrow, it's time for a new phone and I am excited for the s5 anyway. Thanks again for the help,:good:

No doubt you will love the S5. It's a significant upgrade from the S3, which was already a very good phone in it's own right. Enjoy
