NFC - near field communication is a means to receive or transmit data over a very short distance.
If you turn on your NFC and search your neighbourhood you will likely see posters,boards,bus stops with NFC tags on them - hold the back of your phone up to a tag (whilst phone is switched on and unlocked) and you will receive something from the tag.
Depending on the NFC tag you scanned you will get a variety of results - for example scanning an NFC tag at a bus stop usually opens up your web browser and takes you straight to the correct webpage detailing when the next buses are due at your stop.
If you know someone who also has an NFC enabled phone then you can hold both phones together (back to back) and share contacts,web sites and various other things nearly instantly.
You are also able to buy your own 'blank' NFC tags and configure them yourself with an assortment of apps from the play store - i personally use 'NFC Task Launcher'
I suggest hitting YouTube for a more indepth explanation but i hope this outline will help you
My question is in particular what app do I need for "reading" the nfc tags?? I am located in Romania, and here except the biometric passport and some credit cards, I don't know about any nfc tags I could scan.....
But let's take the touching phones method- do I need an app for that or just touch the phones together and you'll get a pop up menu with what 2 share or what 2 do??

In your settings menu you should have an option to turn NFC on. Should be in the same menu as 'airplane mode' etc.
Once you have it turned on then no additional application is needed for reading tags.
You will need a separate application (like the one I mentioned above) to write your own NFC tags.
If you place two NFC enabled phones back just to back then the sender touches his screen and the receiver gets data from them. You can't choose what you receive but obviously the sender can choose what to send.
Though sometimes you can't send exactly what you want.
Your best option is to 'trial and error' NFC. Just sit down with a friend and spend an hour finding out what works exactly and to what extent.

Tried to "read" one of my friends biometric passport. Didn't work directly as the passport tag was (how I found out a lil later) encrypted.
So you must download from the market nfc taginfo. Then go to menu an select passport scan. You'll be required to type the passport nr, date of birth and expiry date. Then place the passport tag under your phone, give it about 20 seconds, and there you have it, passport photo and all the information.
NOTE: you can use any other app for that, but for passport in particular it MUST have the option to introduce some passport info, because of the tag being encrypted. At least electronic (biometric) passports from Romania are encrypted.
I am quite curious how this can be used with credit cards "touch to pay"... Can u somehow create like a kind of wallet in your phone and store the credit cards and just touch your phone with the special POS for those cards and pay? Anybody tried or read smthing about it?
I think it could be done, but I think one could forsee the possible security issues that might appear (eg your phone gets lost).

Dear Reader,
Near Field Communication (NFC) technology makes life easier and more convenient for consumers around the world by making it simpler to make transactions, exchange digital content, and connect electronic devices with a touch.
NFC is a wireless technology with set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contact-less transactions, data exchange, and simplified setup of more complex communications such as WiFi. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".
---------- Post added at 05:00 AM ---------- Previous post was at 04:45 AM ----------
Dear Reader,
NFC requires a distance of 4 cm or less for communication. NFC operates at 13.56?MHz on ISO/IEC 14443 A/B, ISO 18092 etc. air interface and at rates of 106kbit/s, 212kbit/s and 424kbit/s, and higher rates are expected in the future. NFC has two modes of operation: Active and Passive.
In Active mode, both NFC devices generate their own radio fields to transmit data.
In Passive mode, one device generates radio field while the other uses load modulation to transfer the data.
NFC builds upon RFID systems by allowing two-way communication between endpoints, where earlier systems such as contact-less:good: smart cards were one-way only. Since unpowered NFC "tags" can also be read by NFC devices, it is also capable of replacing earlier one-way applications. A remarkably diverse and ever-expanding universe of NFC use cases is being explored and brought to market all around the world. Today, both research organizations and commercial enterprises are putting NFC to work in widely diverse areas.

Dear Reader,
NFC Tags:
These are small RFID chips and passive devices. Any NFC enabled active device can be used to communicate with it. These are manufactured by different companies and can have different sizes, shapes (circular and square) and format (paper sticker, anti metal, card format, key fob, tokens, and inlays). NFC Forum has standardized NFC tags into following four categories to cater for the broadest possible range of applications and device capabilities:
Type 1 is based on ISO 14443 A and was initially available exclusively from Innovision Research & Technology (Topaz™). Broadcom bought this company and now type 1 tags are not easily available. It has a 96-byte memory capacity, which makes it a very cost-efficient tag for a wide range of NFC applications
Type 2 is also based on ISO 14443 A and is currently exclusively available from NXP’s Mifare Technology (MIFARE Ultralight & Mifare Ultralight C). Mifare Ultralight has 48 bytes of user memory while Mifare Ultralight C has 132 bytes of user memory. These are widely used NFC tags across the globe and are available at quite low price.
Type 3 is based on FeliCa technology and is currently exclusively available from Sony. It has a larger memory (currently 2kbyte) and operates at a higher data rate (212kbit/s), which means it is suitable for more complex applications
Type 4 is fully compatible with ISO 14443A/B and is available from a number of manufacturers, including Philips (typical product example is MIFARE DESFire). It offers large memory-addressing capability with read speeds of between 106kbit/s and 424kbit/s – making it suitable for multiple applications.
Thx for the info where do I find NFC tags and how much do they cost?? Any user for a usefull low cost daily application of the technology???

Hi everebody!!!
I allready have the same topic http://forum.xda-developers.com/showthread.php?p=10736841#post10736841 but... its wrong position for it.
So...
Device called the Peek site peek9_com can only receive / send email, witter, facebook. There is no possibility of voice calls (connections) in hardware.
Is currently working on Nucleos OS by Mentor, plus the private GUI of the firm's Reek inc.
Need to port to Linux. Evaluate the possibility of porting.
Work is already underway on peeklinux_com
elinux_org
Problem: the producer (manufacturer) has promised to support the porting (access to gprs module, etc.), but later a support shut up and no longer responds.
In reality this is the case: the device is not locked, but to use it to login on their server (via sim T-Mobile US).
Accordingly, you write off a certain amount of money from the 10 - to 20 dollars per month, depending on the chosen tariff plan.
That is tied to the server from the company Peek.
Works with gmail, aol, windows mail, but through their intermediary server.
Has push mail.
In the States is working very badly, all complaining about the quality of communication, tech support.
Profit device is cheap, simple (only email, twitter, facebook,sms.)
So need to port to Linux,or unlock Nucleus OS - modify...

hello everybody,
as i understand from HTC website that NFC is for communicating 2 devices that has the NFC chip installed (Near Field Communication) .
is that TRUE?
or im missing something here?

Q: What is NFC?
A: Near Field Communications (NFC) is a wireless technology that makes nearby devices communicate with each other as simple as a touch or being close to it.
NOTE 1: The close-proximity makes the transaction more secure.
NOTE 2: Smartphones will have a chip that will enable the two-way communication by either touching them together or being on a close proximity.
Imagine it as a short range bluetooth that can read 'tags' and transfer information between devices (i.e. android beam sends contacts between 2 devices with NFC)
Hope that helps!

Thank you! dude
Some of you must own a Chrysler/Dodge/Jeep vehicle with a Uconnect stereo in it, right?
I've been all over the google search, the Dodge Forums, calling Chrysler's Uconnect dept, etc. and no one seems to have any clue what their talking about. I know that XDA is knowledgeable about all things phone. Searching doesn't get my exact questions, here's an unanswered one for the HTC EvoLTE (http://forum.xda-developers.com/showthread.php?t=1667801). The Ford SYNC systems have a similar problem.
I have a 2012 Dodge Durango with a Uconnect 430 RBZ stereo. It announces that my phone (the Sprint SGS3 with 4.1.1 LJ7 stock non-rooted (for now)) is not compatible with the Bluetooth Messaging Access Protocol profile or MAP-profile necessary to announce and control the SMS messages on my phone. There's a service on our phones that runs constantly when the bluetooth is enabled called MAPSamsungService, which after googling/reading/searching, leads me to believe this is the messaging protocol that the Uconnect desires.
My questions are:
1) Why won't this radio identify the MAP process of the SGS3 and connect to it Are there ROMs that do support this? (CM10 reportedly does support this http://forum.xda-developers.com/showthread.php?t=1916902 - but I don't like the CM10 camera....so...yeah)
2) Has anyone had success in getting the SMS messages functionality on their Uconnect
3) Has anyone had luck with getting your contacts to properly sync? All mine are Google Contacts, and it is VERY random which ones show up. (I have just less than 1000 contacts, which is apparently the upper limit for these radios)
[just in case this shows up in google searches, I have learned that USB drives connected to the Uconnect need to be in FAT32 format and you can only move 2048 songs over at a time to the HDD, so load up multiple flash drives for the transfer. must be constant bit rate not VBR, 1000 folders is limit and 20k songs]
as a former u-connect owner and current audi interface owner, let me offer the following:
When sold, the technology in any car is about 2-5 years old. meaning it was designed to interface with phones 2-5 years ago. so if you have an old phone, it will probably work great!!
Chysler never offered a flash or upgrade to the original uconnect system, but that was supposed to change with the RBZ. My brothers at the LX forum have reported that is not really true. There are some systems that allow you to get around this with aftermarket HU but not what you are looking for.
No way to know what ROM's will work or not because of your specific situation. There is a mammoth black hole where all BT protocols go...no one seems interested in making it generic.
We currently own 2 vehicles under the VW/Audi brand and a Ford with a Pioneer HU in it. My EVO LTE phone book will update in the VW, but not the Audi. Same system, right? In the Audi, it will frequently not sync. one vehicle has different software and Audi cannot flash it. no worries on the Pioneer HU though.
TLDR -> Car companies suck, wha, wha, wha
-----
Thanks for the reply and your experiences. Speaking separately for all the tech they put into every aspect of the car...... I would figure that in 2012, these car companies and their stereos would learn their lesson and start to evolve. I guess we need a Uconnect forum on XDA to really get things heated up! If anyone knows of a site for ROMs and such for these systems, please let me know, I'm willing to take the plunge.
I had an aftermarket Kenwood in my 2000 Jeep Grand Cherokee that I traded in. It synced with my phone perfectly, downloaded all my contacts, but didn't have the ability to read SMS messages (it also had a tiny display). Bluetooth worked well, etc. it just became a real piece of **** car that needed to be replaced.
The latest CM10 logs indicate that MAP functionality was fixed on 11/23: http://mobile.cm10log.appspot.com/?device=d2spr
I really wish that the CM10 camera and data connectivity didn't have so many issues, otherwise this would be a non-point and I'd be happy as can be with full functionality. What I find troubling is how many opinions there are about these different car systems and their compatibility. I understand your point about Bluetooth standards being quite a jumble. You should be required to support them all if you are going to use it in your device. I'm going to back to dual booting CM10 to see if I can get the MAP to work with the Uconnect system.
Then there's the confusion of all these systems. I have read links where a Stock Sprint SGS3 running 4.1.1 worked perfectly with MAP in a toyota prius. You ask Samsung and they say that MAP is not supported by the SGS3, their fact sheets would indicate the protocol is missing. But it was supposedly included in Android 4.1.1, but no one can confirm that.
It's just very disappointing when a company touts a technologically advanced car that can do things like read your SMS messages, display album artwork for songs, play songs from USB sticks, has ipod connectivity, etc. Can't seem to A) do any of those things well and B) offer absolutely ZERO tutorials and guidelines for making the above features actually work. You have to sift through forums to find out that a USB drive needs to be FAT32 formatted!
I just added 26.5GB worth of music to my HDD in my Uconnect 430 RBZ. I ensured that the album artwork was correctly linked with the ID3 tags in all of my music, a painstaking venture to say the least that I was meaning to do for a long time, however NO artwork actually shows up. It did finally all sync over and there are some things that it does "well" but far more that just miss the mark for no other reason than laziness and profitability. Just saying you can do these things is more profitable than actually making them work consistently - OR having knowledgeable people that can help you when you call in.
Overall, I guess I should be happy that it does what it does in the least. I understand the product cycles for cars and the tech is most likely 2-5 years old. Like everything else in this world, hopefully they'll improve their cycle time for updates. Then again, out of sight, out of mind. They have your money, who cares if they add any new functionality. Most cars aren't impulse buys like phones tend to be.
You can use any camera it does not have to be the cm camera. You can flash the stock or the 4.2 or even the note2 camera.apk. Also you xan flash your uconnect with a new firmware

Hi,
I need to find out how to read the Unique NFC ID in smart phones.
Why?
We have an app. this app must identify the unique NFC ID, in order to use the NFC as an identification of the user. Probably quit similar to using the NFC in your phone to open doors? It is just very important that it is the unique ID and not just a info in the NFC.
Our reader will only read the unique ID.
The best solution
Seen from a users point of view, the best solution would be as this:
1. The user pushes an “Identify NFC button” in our app.
2. The app will send a code to the NFC device in the phone and receive the unique ID.
3. Next time the user swipe the phone at one of our NFC readers – the phone/user will be identified.
Any good advice/help?
Best regards
The NFC chip changes the UID with every read, unless it is in card emulation mode.
There is a thread somewhere here that may have the info you want.
Beamed from my Grouper
One of my cars is a 2008 Ford Crown Victoria Police Interceptor. Since it's a retired cop car, it doesn't have any anti-theft system, no chip keys/immobilizer, and there are various keys out there that can easily open/start my car. My friend found a random key in his Crown Vic ex-cop-car from a completely different department and even though the key is cut totally different it still opens and starts my car. I'm sure there are plenty of other keys out there that will work with my car as well, which is why I'm worried about it getting stolen.
I have a spare cheap phone (with like no resale value) on Xfinity Mobile, there are no line fees, so if I can stay under 100MB of data in a month it's free, or it'll cost me $12 for 1GB which is no problem.
Features I'm looking for are:
-Tracking ability
-Text me when the car is started.
-Text me when there is an impact with the car (using the accelerometer in the phone I guess?)
The tracking device is easy... just use Android Device Manager or Lookout or some other remote tracking app. The problem is the other two things... Not sure how I'd accomplish that honestly. I'm a web developer but I have no idea how to even start with Android app development...
Looking for input, hopefully someone on here could point me in the right direction. I've tried Googling/Binging but nothing I've found is even remotely similar to what I'm trying to do. Thanks in advance!
I was looking for the same thing. But all I found was OBD2 devices or some Chinese that used SMS for communication.
But after long time of searching I found ,,carlock,, it is OBD2 but it is using it only for power so you can use only OBD2 dummy for powering it. It has nice APP, using internet and it's not that expensive.
But if you found different solution let me know.
not a dev, but just wanted to comment on what Mato_xXx said about the chinese app that uses SMS.. if someone were to make an app, in some places (not sure if this is the case in China) data is more than SMS and vice versa.. and i know that those chinese made GPS car tracker devices work like this:
-uses GPS to record location
-checks every so often for location changes
-if location changes SMS gets sent to a number you pre-programmed into it every several seconds
these devices come with apps you can download to track the location of vehicle using google maps. Here is an example of said device:
(i am a new user and was unable to post links, but serach for "gps vehicle tracker" in google or serach amazon)
these things meet the criteria of your first requirement without the use of data (it instead uses SMS). If someone were to make a car security app, they should add this as a feature (location via SMS) because depending on what provider you are using you might run out of data or you could go over you data limit and amass a large bill... this would be an issue for people in Canada as we have some of the most expensive cell data in the world
I think what needs to be done is an app that can be installed where you can make it so the car wont start without some kind of authentication entered via your android device + the key..
what I think you were talking about when you said your friend found a key that would start your crown vic is the crown vic fleet key, which will start any crown vic (and usually the glove box and the trunk) ; (again, i am a new user,cannot post links, but serach google for "crown vic fleet key")
and because your vehicle is an old crown vic, its not going to have any wireless daig features so im assuming you'd have to buy some kind of hookup adapter for OBD2 to interface with your car.. but if you make any progress with this project please let us know..
this may be completely useless, but i stumbled upon this while looking for something completely unrelated: (gawd damn new user spam rules again! lol) www[dot]diagram[dot]com[dot]ua/english/articles/security-and-alarm-system-using-mobile-communication[dot]shtml
