Hi guys,
I believe that the NFC chip in my device (battery) is broken. I have tried two different NFC reader applications and swiped my library card, my RFID keyring for work and my gym card with no success. I turned NFC off and on, rebooted the phone, nothing.
Is there anything else I can do to troubleshoot the NFC chip? I want to make sure its a hardware fault before I turn it in.
I have unlocked the bootloader and rooted via superboot, and it's been flashed with yakju 4.0.2 from googles website.

Does NFC enable in settings? Capture a logcat when enabling.
Are you sure that the tags you are scanning operate on the correct frequency (13.56 Mhz)? If so capture a logcat when you try to scan the tags. Capture a logcat when trying to read a tag.
I know this might sound stupid but I'm being serious. Can someone actually explain to me what NFC is, how GNEX can use it and what can be done now with it? I just need it simple terms, searching it online just drove me crazy.
Thanks, appreciate the help.

Thank you for helping. Yes, NFC seems to startup alright according to logcat, no error messages or warnings when I do this. I also see messages "NFC-EE routing ON" and "NFC-C polling ON". The log is too long to post it for you.
I also tried logcat during scan but it didnt notice anything.
No, I am not sure that my tags are operating at 13.56 Mhz... Perhaps they arent. Have to look this up!
Somebody in Sweden knows anything I could test my NFC against?

NFC is for Near-Field Communication and is a wireless communication standard that only operates at a very short instance, eg. 1-4 cm. It can be used as a replacement for regular debit cards so instead of using your card when you go to the shop you just swipe your mobile phone against the shops sensors and enter your pin code to pay. It can also be used to perform a secure handshake, for example if I come to a friends house and I want to access his WiFi, I'll just swipe my phone close to his Wifi Router and they will pair and share the network encryption key. The security in this is that no unauthorized person should be able to get within 1-4 cm of the router to get the encryption key - and NFC simply does not operate at longer ranges then this. These are a couple of things I know are coming with the NFC technology, there's probably alot more stuff we can do with this. Oh btw, we got the Android Beam aswell!

do you have an extended non Samsung battery or just a non Samsung battery? Or is your battery exterior damaged in any way?

see if you can find someone with one of the latest nokia phones with NFC support, or is there any nokia show room nearby, you can try connecting their NFC/BT headsets.
I'm not sure if the GN Near Field Communication (NFC) is the same tech as the Wiegand Proximity cards and readers we have at work. Does anyone know if it would be possible to have my phone transmit my key number so that I could use it on the door sensors?
I asked the IT guy at work and he was not sure. He told me our card readers are Wiegand Prox(imity) 126 bit readers. The access key card I have is broadcasting a number code which I know what that is. I was hoping to be able to program this number code into the GN NFC and use it as a spare access key card.
Anyone?

Android is not capable of card emulation currently.
OK thanks. By currently do you mean they have the physical capability but no software has been written? Are you aware of plans to add this in the future?

After looking around the NFC hacking sub-forum, i can say it's not going to happen anytime soon. I read a lot of post over there that says you need access to the Secure Element which is not going to happen(at least now)
OK well thank you for the answer. that is unfortunate. It seemed a nice addition to the phone's capabilities.

Should be possible on 4.4
I believe android 4.4 should allow this now:

Unfortunately I've not seen an implementation yet
What exactly can we do with NFC on our device. I've tried everything to get google wallet to work and I'm convinced it won't work. So what else can I do with NFC?

Yea I've tried a dozen things to get Google wallet to work. Think a lot of us have lol. But we can share YouTube videos and web addresses and contacts and I'm not sure what else

The NFC section of xda could help lol. Hell, we could even scan those weird Skylanders figures they have. Basically plastic figures with NFC tags in them

Until Isis becomes available for our devices we don't have a "wallet" solution. Also when it does become available you will have to get a special GSM card that has the secure element in it for it to work. To my knowledge it's in a beta test in two cities although it escapes my memory which cities, plus your device cannot be rooted as of right now. Moving on you can kinda sorta automate yer device with NFC tags. For example lets say that you are going out for a drive you can swipe a NFC tag and place you place your phone into drive more with Bluetooth on and the GPS. Or when you go-to bed swipe your phone and have it go into silent mode and dim the brightness of the screen. Out side of that and stuff like that not much for now........

NFC has kind of limited usages right now. I'd say the most common are NFC "tags" on stuff like posters that replicate what QR codes are currently used for, and it's also used to bootstrap more complex connections (like WiFi or Bluetooth).
The big "thing" for NFC in phones was Google Wallet, but there was a big hullabaloo and, apparently Google Wallet will not work on SIIs which lack the "Secure Element" part which is where payment info was supposed to be stored. There's the alternative of affixing an NFC tag physically to your phone and using it that way. Don't ask me why Wallet couldn't just be made to work without the extra security. There's a lot of muddled announcements about it, especially with the Wallet vs. ISIS fiasco.
I downloaded the app NFC war by radiowar and whenever I click on read a card
or war it tells me to touch a NFC tag but when I do nothing happens..
Could someone send me a tutorial for this app or explain to me how it works?

Not sure about the specific app, but typically with NFC (RFID) make sure:
1. Your phone has NFC capability and is turned ON (yes, there have been people trying it without their phone supporting it!!!)
2. Make sure you know where the NFC antenna is on your phone and place the tag right on top of it
3. Maximum distance between the tag and your NFC antenna ~3cm. It might work at greater distance, but typically the shorter the better
4. Your NFC tag is working! If one does not work, try another one. Dead tags is not uncommon.
5. The application may not be compatible with your phone's NFC chip! In that case, the app will simply not work. Check with the developer regarding compatible handsets.

is this nfc an hardware, my phone doesn't have, can I get it with rom updates?

Yes, NFC is hardware. If your phone doesn't have it then you're out of luck.
Might have figured this already but sometimes you need to leave the card on for between a minute and 30 seconds before it can read all the data
I'm moving into a new appartment, this is the key for the building it is in.
It says Simonsvoss on it, its the name of the company.
You just have to hold it in front of the lock and it opens automatically.
I thought maybe it uses NFC and you can read out the key and also use your phone as a key.
I tried some NFC reader apps, but none of them got any signal.
I'm not sure if NFC works on my phone (i have a galaxy s3 with cyanogenmod 11 M6 installed).
Anyone knows if this thing even uses NFC?
I'm no expert but it was my understanding that nfc is Bluetooth and these fobs use some other radio signal

There's a number of different reasons why your smartphone can't read it:
- it doesn't support that particular tag: it does happen, perhaps it works on a different frequency, or uses unknown protocols. There isn't much you can do about it.
- that key is not an nfc tag: it sounds unlikely to me, since the way you described how it works makes me think it is actually an nfc tag, but who knows.
- the cyanogenmod you installed doesn't support nfc: have you tried reading other tags with it? What kind of software are you using for reading it? Make sure you can successfully read other kinds of tags: if you happen to have Mifare Ultralight tags, you may use an app I developed a few days ago, UltraManager. if you have other kinds of tags (even the most recent passports have nfc tags embedded), apps like NFC TagInfo should do
- you have accidentally removed part of your nfc hardware accidentally: I know this sounds unlikely, and I would've never suggested it, but earlier today I talked to a guy who claimed he couldn't read any tags: turned out that he had changed his smartphone's battery with an unofficial one, and since that particular smartphone had the hardware on the battery, he obviously couldn't use nfc.
I know this thread is dead, but...Probably not NFC, since I can even scan and copy my Passport (hex codes of fingerprints and so on).
Would be to easy to break into a appartment secured like this

Radio Frequency
The Transponder is a radio transponder, it unlocks the lock by sending a radio frequency which cannot be cloned like traditional RFID ..
Simons-Voss stated this information on their website, in fact that was their main selling point is that the transponders cannot be cloned .. I know this thread is old and all, but I would be interested to know if anyone has figured out a way to hack these locks. I used them, so I am interested to know how their level of security is holding up after all these years ..
