NFC from T Mo battery - Samsung Epic 4G Touch

I was wondering if we can just use the T Mobile SGII battery to have NFC

No. I don't see hiw that would be possible. There has to be something built into the software as well or all phones could have it.

Ok, I understand the words being used but not exactly how they fit in with our device or cell phones in General. Is it like a Walky Talky type near field or like Bluetooth type near field? A link to explain why someone would think it is in the battery and what the OP was referring to?

It's like BT.
It is not in the battery.
Some reviewers have gotten a hold of prerelease phones, and their batteries had NFC markings on them... That's as far as this story goes.

Actually its neither, its more like extremely close proximity RFID transmission, the 2 devices using the NFC will need to be within a foot or less from each other for the NFC to work.

I thought it would be in the battery cover like the Nexus S. That would never work.

I would say its in the battery cover like the Nexus S... The cover has connectors and so does the phone. Once the lid is sealed NFC is activated.

I tried with the nexus s and works pretty good, and google gives you $10 free to try it. It needs the sensor in the back plus is small chip inside the phone that stores your credit card information and it is only accessible but google wallet app and no the system so is very secure. like I said I tried and works nice.

Thanks for the replies. Is this for electronic payments?

inductive charging?

anybody know what the pins on the back of the battery cover are for? it looks like what you would find on a phone capable of inductive charging. if so, anybody figure out how to do it?
They act as an antenna, dont **** with them
hmm ok. ill have to try it with the cover off to see its actually the antenna but ill take your word for now.

it does when i was playing with my phone without the backcase on i had no service
I only get 2G service when the back cover is off. I think it has something to do with the antenna as well.
I actually was wondering what the pins were for. I just took my back cover off and immediately dropped all signal.
thats kinda weird to have an antenna in the back cover. maybe they plan to release a new back cover that will improve strength? i cant seem to understand why.
Its just the design. And it saves space on the device.

HTC states that the battery cover of the aria is the antenna on their website under troubleshooting:
My device shows “No Service” but I know that there is coverage at my location. close
The antenna for this device is embedded in the battery cover. If the battery cover is not installed correctly, securely affixed, or if it has been damaged, this could be the cause of the device not picking up on a signal.
You can find this on www(dot)htc(dot)com/us/support/aria-att/help/phone

lol, it tells it's an antenna in the manual, I know, I'm like, the one guy that still reads those...

Weird coincidence..?

Sometimes when I place my Galaxy Nexus on my Macbook (after sending a message particularly) my Laptop just goes to sleep...
It's really strange and was wondering has anyone experienced the same thing?
Just wondering would it be something to do with the NFC chip in the phone interfering with the laptop in some way..?
have you been able to reproduce this multiple times?
if not, then its just a coincidence
also, try disabling nfc
(go into settings>more> uncheck nfc)
and see if it still happens
Apple uses a magnetic sensor to put it to sleep you may be triggering it based on where you set the phone

My flatmate has the same laptop as me and when he places on top of mine his goes to sleep (but mine doesn't - his Win7, mine Linux). Probably not related though!
Good enough answers for me!

All GSIII stuff should fit all versions. On the outside they are all the same from what I have heard.
From what I have read, and someone please correct me if I say something wrong here, I believe the OEM batteries also contain the antenna for NFC. So, unless you don't care about that, you would want to make sure any replacements also have this.
I must admit, after the initial novelty of the NFC stuff wears off, if I find that I am not using it, I would consider A larger capacity battery.

Can't be in this case, as Samsung is selling a second battery with one of the chargers. That wouldn't work. (Not the the ATT one will have Google wallet anyway)

It is correct -- it's the same as the SGS II. The official Samsung batteries have components necessary for NFC to work. There are other generic batteries that work, but you'll lose NFC functionality.
Google Wallet is one, but since only Sprint has it, no biggie. But on the SGSIII things like the new S-beam use NFC, so if you don't want to lose this functionality, you'll want to stick with official Samsung batteries for the time being.
(Not aware of any generic batteries with the NFC components at the present time)
i would not ever use 3rd party battery...
not even sure how to use NFC . just touch a phone with nfc also and it works?

'cause unless it's a brand name/well known company (Duracell, Mugen et al) you don't know what you're getting- you can be burned literally and figuratively. Cheap isn't necessarily good or electronically safe. Li-ion batteries are dangerous if improperly made.

Jogging with the note

I imagine it won't be a very practical endeavor, I'll probably use my s4 for when I do exercise. What do you plan on doing?

Much better than the Galaxy Gear faux-smart watch.
just swap sims and you're good to go.
I'm really considering this as well because both the Note 2 & 3 are huge and clunky while working out.

I used to use one of these while working out. Locked the screen and disabled the Changing of tracks with the volume rocker. That way there were no accidental track changes. I lost the Nokia bluetooth adapter and have ordered this as a replacement.
The main reason I like this style of bluetooth adapter is that it allows me to use whatever set of headphones I want to. I just wish someone would make one with Apt-X.

Why not just get an armband?

Pair with some bluetooth headphones and go.
Whichever arm that you put that arm band on would definitely get "jacked" after running with that on.

I found the pedometer pretty interesting so far. I did a 1.5 mile walk yesterday and used both S Health and Runtastic for tracking. Both apps were spot on for distance, but were off by 50 calories of each other. So runtastic tracked my distance by GPS and S Health tracked my distance by steps. I was impressed.
I also like the fact that you can turn off the screen and it will still track your steps.
I use fitbit for weight tracking, myfitnesspal for calorie intake and runtastic for walking, cycling and heart rate monitoring. While S Health is more nicer looking and has everything rolled in one, I don't think I'll use other then for the built in pedometer. But I'm thinking on buying a BodyMedia Link for a more precise daily calorie burn.
Also I can't get S Health to detect my runtastic heart monitor. It says it will work with the Wahoo monitor which, I think is just a rebrand.

How much does it drain the battery to leave it on all day? I used the "Moves" app which is kind of like S Health without all the excessive features (basically just a pedometer) and my battery drained around 20% more every day, so I stopped using it. (On a Nexus 4 though, thats why i'm wondering what it is on this phone).

I haven't noticed any battery impact thus far. But while at work, out of habit, I plug my phone to charge. I also pause the pedometer when driving and if I'm going to be sitting for awhile.

Thats good. I guess thats why samsung has all those sensors on the phone.
I'll probably get some cheapo MP3 player to jog with, possibly a iPod Nano. Granted I've jogged with my Note 2 before, it just becomes kind of a chore to hold and run with.
Been using a spibelt (http://www.spibelt.com/) for years (g1, galaxy vibrant, g2x, s3) and found that the Note3 just barely fits (i dont' have a case yet) in the big pocket of the 2 pocket style belt. No bounce at all while running.

My gear works quite well thank you.
It does, but the problem is that it needs a phone to make it "smart." I believe it's not self sufficient.
I'm not knocking it, it's a great effort. But, it's hard to ignore that it is more of an accessory to the galaxy devices, rather than a stand alone smart watch.
I was getting one myself when I first heard about it, but seeing it's limitations, I don't think it is justifiable to shell out 300 for it.
Granted, the gear 2 will be just amazing. Look at the note series... The 2nd and 3rd revisions are just awesome.

Proximity question

i have a simple question (i think).
what is the maximal distance to a NFC reader device to get the signal ?
thanks.

I've heard that it's round 4 in but I highly doubt that. I've only ever been able to get it to work by actually touching the devices together.

It would depend on the reader, Ive had something work from a good 10cm away

The NFC chip in an Android phone is usually in the battery right? I would think that they would make them low power and compact, as to get as much space out of the battery as they can, which would mean that unfortunately, they would have a shorter than average range, right?
It seems counter productive to put such an important chip in the battery, but according to Samsung it is located in the battery and the maximum distance is 20 cm to allow through cases but short enough to provide security from would be data thieves
Sent from my SAMSUNG-SGH-I537 using xda app-developers app
Theoretically a scanner can read a chip up to 10cm away, though realistically it's more likelly gonna require a maximum distance of 4cm.
from my experience, not more than 5 cm.
In my experience, with phones and those HID security card readers, the distance is almost nothing. With phones, about 3 - 5 cm, and with HID cards, about half an inch.
