I know what NFC is, as in I know they are some kind of tag, I assume sticker like, and the phone can grab information from it.
But what is the uses? I have read in passing about how some people have them all over, and use them all the time.
I am curious as to how I can use them as an advantage, and what kind of things they can do.
Thanks in advance.
You could buy a generic $10 car dock and stick a NFC tag on it that will launch "Car Home" (or maybe "Navigation" on the maguro) once the phone is docked. obviously you would have to dock and wake the phone for the tag to be read, but I actually think that is ideal
You can have a tag that launches a Tasker task that turns your phone's screen off. So, if you have a spot on your desk where you commonly set your phone, you could place the tag there and it will turn your screen off when you lay your phone down (and save your power button)
Limited only by your imagination, really.
You can buy tags, stick them anywhere, and program them to do anything you want when you touch the phone to the tag lol.
Turn on/off WiFi when you leave the house, turn off your ringer at your desk, enable BT and car mode in a car dock, etc. etc. etc....
Look at this video

its a Blackberry.. but it works the same way as with Android.. just different app.. same sticker
I find it to be useless tho in a way.. i can't wait to use NFC to unlock doors and replace ID n security check points.. Google wallet is the way of the future without these stupid bugs and hacks
OP, for future reference... use the search feature before posting something like this.
I will not do this, but you will get flamed for posting a question that already has a thread.
Anyways, just check out this thread...

Personally, I have tags set up at my bedside table, door at home, in my car and at work to launch different "profiles" depending on my current location.
Try the app NFC ReTag https://market.android.com/details?i...=search_result
It doesnt change anything on the tag. It recognizes a unique tag and execute actions you set on your device. That way, you can reuse old hotel keycards or even antitheft stickers on clothes you bought.
I get that you can programme actions. But for location profiles aren't you restricted by having to remember to tap the tag?
I use Setting Profiles and rely on it all happening automatically based on time and place from cell towers and wifi. What's the advantage of nfc?

Also, is it possible for my phone to replace tags like door fobs etc or is it just a reader?
Yep, I wished there was more to it, but that's the extent of it. The target needs to be able to process and have battery power to open up real options.

NFC doesn't require me to leave GPS on. Nor does it require me to change something if I don't want to. If I don't want to use that profile, I merely do not touch the tag. No need to turn off programs or anything else.
There is more than one way to skin a cat. NFC isn't revolutionary, it is just different.
Where can I get NFC tags? and do I need an app to make them do what I want?
What kind of range do they have?

Yes you need a app to use it with
And NFC is short range

How short range is short range though?
Could I put one on the under side of my counter top? Would it work at all or would it give me a 6" radius? ?
For the tag to work do I need an app open? or just have the phone not sleeping? like just have the lock screen up?
short range in this case is an inch or less.
NFC only works when phone is awake with screen on.

How do you use them and for what?

There are several threads on this. I have not used them yet myself but plan to. My understanding is you need an app, either to program their functions or to recognize them or both. Then you are only limited to your imagination.. Say you put one in your car, touching it will then turn off your wifi, turn on your gps, open Google Nav.. Or put one by your door at the house, you come in from work and it turns off your gps, turns on your wifi, turns on call volume & opens your tv schedule app or something.. Whatever you can think of. Others feel free to correct me where I am wrong.
So its an electronic you have to buy?

Just seen some apps for editing some nfc tags. why on earth tho would you want to edit it so that when a tag is scanned it opens the browser etc? why? if you want to open the browser why not just open the browser? maybe i missed something?
i have a key fob, is it possible to read the key and copy the information to the phone so i can use the phone to open the door?
You are missing the big picture. These NFC capabilities are only limited to your imagination, so first you need that.

Can't tell if troll or just stupid.
Anyway, the capabilities of NFC are just starting, such as checking in with Foursquare or making a purchase with Google Wallet, or even using it to Android Beam. Think of NFC as "just developing", because it is.

You could always try the threads about NFC with ideas of ways to use it.
right ok im aware of beam and wallet and that but thats not my question. maybe the title wasnt exactly accurate, like obviously theres all these possibilties blah blah. but im asking about the current nfc apps available.

This isn't the first thread on the subject, but I'll humor you.
I have an NFC sticker inside my car. When I scan it upon entering the vehicle, my phone automatically disables wifi, sets the ringtone, notification, and media volumes to 100%, and launches my music player. When I scan the sticker again on the way out, it turns wifi back on and quiets my volumes.
Another tag that I use all the time is a sticker affixed to the outside of my leather slip-on case. It is tied to a Tasker task which locks the display when the phone is inserted into the pouch in case I forget to do so.
Sure, you could do that all manually, but it gets to be kind of a pain. It's a lot easier to just turn on the phone and scan a tag than to change several settings at once.

No need to be a ****...
Obviously you wouldn't want to use an NFC tag to open your browser, but it has a lot of potential. Of course you have the normal Beam and Wallet applications, but there are also other cool things like using NFC tags to silence the phone at work, put it in Navigation mode in your car dock, or turning up the ringer when you leave the house. NFC is a standard, and its up to you (and phone/app makers) to come up with cool things to do with it.
Look at what Nokia is doing, things like using NFC to pair Bluetooth devices.

The possibilities are endless. They are mainly used for complex routine tasks. Take the following examples and compare to doing all of them manually:
Seeing up directions in a car dock. You can automatically set the phone to enable GPS, fire up nav and pair bluetooth with your car stereo.
Going to sleep. Put the phone on your nightstand and it automatically silents, sets your alarm and switches to the clock screen.
Going to work. Place the phone on your desk and it silences all notifications and can enable an autoreply to calls or texts saying you're at work.
Those are just three examples of where it could come in handy. If you don't have any routine tasks done in the same place then maybe NFC tags aren't worth it to you.
Which app lets you copy an NFC id tag, and then transmit that tag from the phone to another NFC receiver?
I find NFC fascinating technology, and have lots of tags to play with. But the biggest barrier to putting them to good use is that NFC doesn't work while the phone is in standby. For example, I could put a tag beside my bed and put the phone into silent mode automatically. But if I have to switch on, unlock the phone and touch the tag, I might as well have just dont the task normally. But if I could leave the phone in standby and all I do is wave at the tag...that would be amazing.
Can it be done?
alicechong89 said:
The NFC function isnt turned on until you get out of the lock screen I think.
I've read in some other forums/threads that this is not possible mainly because of security reasons.
Example: If there was a stranger next to you with their NFC Tag really close to your phone, you wouldn't want your phone to detect the tag automatically without you knowing.

Thanks. The tag has to be REALLY close to trigger anything. But I think that should be a user choice rather than a forced one. Disappointing...maybe Android will change in the future to allow this.
It was introduced in ICS. With gingerbread it wasn't necessary to unlock your phone to read tags - I used to use a tag to toggle my pin lock screen & WiFi/data connection, which was quite nice.

I understand Google's concerns about security, but this is a poor solution. Having to turn on and unlock the screen completely removes one of the advantages of NFC technology - speed.

I agree with this.
Just started using NFC this past week and kind of sucks you have to unlock the phone to use it.
I wish there would be an option that we can choose this setting.
Hey guys. I was wondering if there's an easy way to make an NFC toggle such that when the tag is within range a) happens and when it goes out of range b) happens. Essentially I want my phone to into silent mode when i place it on my nightstand and go off silent mode when i remove the phone from the night stand.
I know a "workaround" is to make the tag toggle for each swipe but if possible I'd like to not have to swipe a second time to remove silent mode.
Any ideas?
Yeah, i'm looking for the same... i'm not sure if there is such a thing.
maybe one way would be for an app maker to have a feature where the nfc will be checked say every minute to see if it's still within range. if it is, leave the setting alone. if it's out of range, it will do the 'out of range' action. shouldn't draw much battery I don't think?
I want this feature so I can put a tag in my car so when i'm in the car, it will turn on bluetooth, and when I get the phone out of it's spot, it will turn BT back off. (so it's only on while i'm in the car)

NFC tag to turn BT on, then use Tasker to turn BT off after it looses connection to your car BT device.

that seems like a great app, but I don't think I ever paid 7 bucks for an app lol... and i've gotten some great apps for much less. just saying...
good idea though.
Tasker is well worth its money. You can replace so many apps with it that in the end you'll end up saving loads of money

I've used this in my car
I've faced the same problem in my car.
I've put a tag on the phone mount, when touched it enables car mode.
I've used tasker to take the phone out of car mode when my bluetooth HFP get's disconnected (when car is turned off, or I'm more than 5 m' away).
I can also do the same when the phone is unplugged from the car charger.
It's not perfect, but will work unless you turn the car of without removing the phone, and then on again (no NFC tap to re-enable the car mode).
Hope this helps someone
Hi,
Just wondering if anybody has tested the NFC functionality? I am currently using the Smartband - and I use the NFC on the Core with Xposed Framework to unlock my phone (Xperia Z1). Aside from dealing with the annoyance of having Lifeblog constantly launching upon unlocking - I find it quite useful without having to enter a PIN every time.
Not many details on the location of the NFC antennas on the SW3. Wondering if I can truly replace the Smartband with the SW3.
There is smart unlock feature in lollipop so it will not ask for pin if smart watch connected, I believe you can achieve similar with xposed or 3rd party apps on previous versions of android
NFC works
If you got NFC on your phone turned on the phone recognizes the watch by bumping and opens the android wear app.

If the watch is off, nfc contact also turns it on.
I was testing SW3 NFC with newly purchased Sony SBH-60 headphones. No luck - nothing activates. The headphones worked fine once manually paired, but in my opinion NFC does not work, most likely is not supported by Android Wear yet. Which would be another big disappointment - no LifeLog app on the watch, no sleep tracking with use of Watch, no Walkman app, now no NFC support.

So far, so good. Everything works as advertised and nice sound, overall yet I'm not an audiophile to comment on a lot. I think you should not worry about pairing with Nexus 5, but I can't tell for sure, no N5 around to test

Yes, this is the only feature that works. Not really useful.
Thank you BartManx, I'm also not an audiophile so I guess it'll be good to me too.
Until Android Wear starts supporting NFC, it's hard to test the full capabilities of NFC on the SW3. As others have reported, right now it just opens the Android Wear app on the phone.

I can't sync with Galaxy note 4. Any solution ?
According to the owners manual the NFC antennae is in the centre of the screen. Which makes sense so it can be used while on your wrist.

If you don't have Lollipop, but you have a rooted phone, NFC and Bluetooth can be awesome.
I hate using a pass code. I like waking up my phone and going right to what I want to do. However, if I ever leave my phone unattended, it would be nice to know that someone can't just get into it and start messing with things. So, I have a rooted LG G2 running Xposed. There is a module called: "No Lock Home"
In a nutshell, after you enter you Bluetooth address of the watch into the module, if you are wearing your watch and you walk away from your phone far enough to break the NFC/Bluetooth connection, the phone goes into lock mode (meaning you need a pass code or pattern or whatever you set up); once you come back into range of the phone, the pass code/pattern lock goes away and you're free from having to take the extra 3 seconds to "unlock" your phone.
Technology is the bees knees!!
There is an app called Skiplock which I believe is made by someone on XDA which does the same thing but without the need for root. You can use BT or Wifi for keeping the phone unlocked.
I'm not sure if my sw3 doesn't have (dont work maybe?) nfc or my nexus 5's nfc isn't working. Anybody could show me what happen when the sw3 is close to a smartphone?
EDIT: found it https://youtu.be/4YStUt_RPKs?t=5m7s
So or my nexus 5 nfc is fkd up or my sw3's nfc is fkd up lol
EDIT2: Ok solved. The replacement part I got for my nexus 5 was broken. I got use the nfc+wireless recharging combo from my old (original) back cover.
