Now that i have your attention........i was playing around on play.google and i found an nfc program that will allow you to repurpose an old nfc tag...well i got to a-thinkin...., my kids have the game "skylanders" for the wii and computer... now if you dont know what skylanders is, it is a video game with NFC figurines that have special powers. You place the figures on a NFC reader called the "portal of power"...moving on. i was thinking "hmm....i was not able to read these before, so i wonder with this program can i read these figurines. Now mind you i had installed an inductive coil into the battery cover of my phone...I installed the program and grabbed one of the figurines and low-and-behold IT WORKS!!!!! the inductive coil does not interfere with the NFC coil....just thought y'all wanted to know...

Thats cool. Any pics of how you have the coil on your cover? Stock back cover?
^this
yeah its the stock battery cover, and i just taped it on with good ol' fashion electrical tape. i believe in my other thread i show the inside of the back cover and the out side of it.
On a side note, were you able to read them? I've been using NFC TagInfo and am 0 for 5 trying to scan various things that I know have NFC/ RFID.
Lol spyro???
And it would be cool to have an rfid reader for the phone

This, cant find on google anywhere...
I tried finding compatible devices that work with the Powermat & couldn't even find that.
I do know that several people have hacked their device to work with inductive charging but it takes some major surgery and skill to get it to work.
So as of yet I'd have to say "no'
I saw a powermat kind of thing at radioshack and it says on the box works with compatible devices or need "power discs" but no one can "find" a power disc in the system or even what they look like.
would REALLY love to get wireless charging and I don't mind a little surgery
I did find something called a Duracell myGrid Power Clip, but I would rather have a case so it is pretty much "seamless"
Search inductive charging. Its in or forum
He already got it up and running but definitely takes some skill

So I think it's finally time to get this going. I'm going to be taking apart and installing Touchstone wireless charging into my Hercules Galaxy S2. The parts are on order (I was going to do this with a PowerMat charger I had lying around but then I found out it's not compatible with the cheaper touchstone system so I ordered that instead). Should be getting pictures and guide (maybe video too) by the end of next weekend. Stay tuned.
This will be awesome!
Pretty cool thing.
Someone else did it with a touchstone dock. The microUSB port is kind of blocked, here but the kid who made it has another version of it, as well, with hidden cables and whatnot.

I saw that. The idea with this mod is to be similar to his Galaxy S mod that has the free USB port. I'm not a fan of wires sticking out. Should be getting the Touchstone gear tomorrow and then the foil on Friday (copper foil). I'll do a bigger write-up when it's complete including materials and directions. As far as I know, nobody has done this yet with the GSII, which is why I want to do this and kind of add on to what the other guy did but for this newest generation
This is gonna be awesome.
I nearly broke my Vibrant when I did that last year. I'm not going through that experience again.
On a bright note: I now know how to completely take it apart and piece it back together in 5 minutes.
very excited for this! looking forward to the results/write-up and maybe if i have the balls ill give it a go myself . Good luck.

Question, Could the TouchStone interfere with the NFC communications ?
had no idea there was no support for our phones on this, i'm definitely interested as i dont like plugging and unplugging my charger all the time It'd be even more awesome to intuitively convert this into a wireless car charger haha
What would be really awesome is if there was a way to not only have wireless charging but have like a 5 for radius for the charging as well that doesn't muck with the NFC

This was my first thought... would the induction field pump power into the NFC antennas and cause damage... but I'm not an engineer which is why I love the XDA community.
I dunno of it would mess with the NFC coil but I am thinking not unless it is "tunned" to the same frequency as the induction coil, them again on the other hand id that was true then we couldn't have our phones around ANY magnetic field. I would wager that the NFC coil may be grounded out already somehow, that is not to mention that it is "tunned" to a specific frequency as well...... justa thought

Induction Mod completed
I attempted the induction mod and was successful. I soldered a wire to the same pin as shown in the video for the Galaxy S. I need to clean it up with copper foil tape but it is functional. Putting the battery cover back is difficult because of the limited space between the battery and cover. I didn't take any pictures but if anyone has questions I would be happy to assist.
Can you take some pictures so that we can see and how snug was the battery cover? Does it interfere with the NFC?. Right now I an rocking the nexus extended battery and it's cramped to say the least

My only camera is my phone so I can't take any pictures. I have not tried the NFC function on my phone but I think the coil may interfere. As far as the battery cover is concerned, there is not enough space if you are using a larger battery.

So I successfully implemented inductive charging into my Diztronic case so I decided to buy a few NFC tags to launch specific things when on certain Touchstones. Here I come to find out that when I put the NFC tag onto the touchstone the phone wont charge AND it won't detect the NFC tag. The tag works fine as long as it's not on the touchstone, and the touchstone works fine without the tag on it. Has anyone else encountered this issue and/or found a solution to NFC tagging touchstones?
On a side note, what is everyone's favorite NFC writer app? I'm currently using Samsung's new TacTile app and it seems to work pretty well (besides on my Touchstones...)
Some people have reported some strange NFC behavior when using inductive chargers, often when the charging coil sits right on top of the battery. The only possible fix would be to nudge the charging coil up so it doesn't sit over the battery as much.

I have a Samsung Galaxy S3 which depends on the battery with a built in NFC antenna for NFC to work. I am currently using a 3rd party battery that doesn't have an NFC antenna. I would love if there is an option to somehow add an antenna externally, but not through the use of a microSD card if possible. Does anyone have any suggestions? Thanks!
Doubt it. NFC isn't just a matter of adding an antenna afaik.

It would be really be more feasible to just buy a different battery with NFC support. Trying to add an NFC antenna to the phone would be a lot more work than it's worth.

I assumed the rest of the required hardware is built into the phone and just the antenna in the battery, but then again the antenna probably needs to receive power so I can see how that would be an issue. Thanks for your input.

Actually on the SGS3 the NFC antenna is in the battery, not the phone.
Sent from my Transformer using Tapatalk 2
Actually I knew that since it was stated in the first post. I consider that still inside the phone.
I thought the user I answered to imagined something like this here as an nfc antenna.
While technically yes, you could make an antenna out of say aluminium foil if you could figure how to cut it so you end up with a tuned antenna, then connect it to the correct pin on the battery connector, I think any sane person would just stick an NFC battery in.
I think they put the antenna in the battery because it's up close to the back of the case. That would also keep it well away from the other antennas that I doubt would like the power pulses that NFC puts out while it's polling.
Oh and Damastus, that picture it hilarious.
I've done the wireless charging mod using Palm Pixi guts. That thin coil of wire is enough to break NFC communication, depending on where it's put. NFC has a VERY short range, so I'm sure it's in the battery to put it as close to potential NFC chips you want to read, and to minimize anything else getting between the antenna & chip (like cases, batteries, etc.)

On the Nexus S, the antenna is built into the phone's backplate.
In theory, you could buy a Nexus S back, remove that antenna, and put it on the inside of your phone.
Run fine wires from the phone's NFC antenna connections to the antenna, and it might just work.
I'd expect reception to be lousy, since you'll detune the antenna by trying to connect it. This also assumes that the NFC circuitry is in the phone, and the battery has only the antenna.

I got my extended battery (4300mAh) with NFC support from a Chinese manufacturer for only $15. I know you have to be careful with those, but this one seemed legit so I took a chance and it works great - last forever - AND has NFC.

just take apart an OEM battery and start playing with it. My guess is what you want to do is VERY doable.
If I recall correctly, the Verizon SGS3 inductive charging back cover has the NFC element on the cover, not the battery.

I think you're right, however I'm pretty sure that's what the extra two pins under the battery are for. These pins are only on the Verizon version of the GS3 though, so it wouldn't work for my T-Mobile GS3. Thanks for the suggestion though.
buy a cheapy chinese battery that has NFC and "have at it"
As far as I have known, there is a type of NFC antenna available in the market that can be stuck to the back cover of your Galaxy S3. In this way, you can take full advantages of NFC functions of the Samsung mobile with an alternative mobile battery. However, it seems that most providers like Sunshine Good Electronics Company only do wholesales business on platforms like Globe Resources. You can search it on e-bay, maybe you will be surprised to find on retail seller.
Hey, I have a fake battery bought from eBay that looks exactly like the original one but it is fake.
The problem is that it doesn't have NFC support. NFC works fine if the original battery is inside.
Since the battery just acts as NFC antenna, maybe it is possible to out something conductive to touch the correct contacts and NFC will work.
Did anyone ever try that? Does anyone know how to do that?

I searched around, doesn't seem like nothing what you are suggesting has been done; Also, no hits on Google;
I would advise you to simply buy a NFC-capable battery. Messing with li-on batteries is not a great idea, IMO.
But that's not FUN
I'm not going to mess with the internals of the battery, just create an antenna that happens to be glued to the sticker of the antenna but could really be anywhere else.
Update: I did it!!!!!!!!!!!
Pins 1&3 are power, pins 2&4 are NFC (1 is leftmost pin)
I connected a bit of copper wire to each of the NFC pins, and connected them using coil (wrapped 4 or 5 times).
It reads NFC tags very well, the only problem now is I can't close the back cover because of the giant coil. I'll try to find a solution to that and upload pictures (or video), because as we all know "pictures or it didn't happen".
Update: The project FAILED.
I tried to connect the two NFC pins using a coil. When the coil was away from the phone, it worked very well. When the coil was on the phone, it didn't work. Since I wanted to stick it on the battery and be able to close the cover, I must say it didn't and can't work.
The fake battery is blocking NFC signal. If you put the good battery in and then put a tag -> NFC success sound.
If you put good battery in and a tag+fake battery over it -> No sound. Take the battery-> Success sound.
That concludes our experiment.
Real Samsung batteries with NFC are available on Amazon for $8.
+expensive international shipping. I'll stay with one battery that does NFC and one that doesn't, until my next phone.
I'm considering attempting to remove the antenna sticker from my old battery, stick it onto my new third-party battery, and connect the leads to it's pads. Will update if it goes well. Or if it doesn't.

Welp, that didn't work.
The nfc sticker on the stock battery seems to fall apart if you try to peel it off.
