I just discovered that such things even exist, and I'm intrigued by the idea. You just tap the tag with the phone and it can do stuff? What sort of stuff? How much stuff per tag? Do I need specific types of tags for the S4? I'm sort of geeked up by the idea of making my phone do stuff like it's magic.
I myself am just getting started with nfc tags. The 1 thing I've read about most is to automate a few tasks, for example when you get in your car and tap the nfc tag you can have the phone turn off wifi, turn on mobile data, turn on bluetooth etc.
I currently have 1 tag that I leave on the dash of my car and it is set to turn off wifi and turn on gps and bluetooth. I also have programmed the phone to say "welcome to the bat mobile"! (just to test it out). Also, on tapping on the same tag again when I'm home it does the opposite but says "welcome home".
The Galaxy S4 will work with NTAG203 nfc tags and not the older mifare 1k tags, as far as I know.
To get started you'll need:
1) NFC Capable phone
2) NFC tags. (I got some NTAG203 from eBay. 5 tags for $5 incl. shipping).
3) An app such as NFC Task launcher. I find this app to be the best and for some reason I am able to write more data to tags than for example the Samsung Tectile app.
Once you have the app installed and the tags. It's actually quite easy to get going.
There could be commercial uses for these tags if you own a business. You can program your company's website/address/phone and place them for marketing. People who have nfc capable phones can then tap on this tag to get the information.
Hope this helps!
Very interesting. It sounds like one could, for example, place a tag on a phone holder and have it launch Google Navigator. What would be even better is being able to execute a command after the app launches. That way, it would automatically ask you to speak the destination.
Sounds pretty cool.

I have never used NFC tags either, coming from Apple devices. You mention that you have a tag in your car holder. Does this mean that the navigation app etc starts when you place the phone in the holder, and then quit those apps when you remove the phone from the holder? Or do you have to remove the phone and and then touch the NFC tag once again to deactivate the navigation app and such?

From what I've read, you're right. I also found this thread discussing the differences and actually mentioning another type that works with the S4.

Yes the navigation app starts when you place the phone in the holder, however if you are talking about using the same NFC tag, the app will not quit when the phone is removed.
One NFC tag can only perform preset function(s) all at once, in sequential order. So if the NFC Tag is set to program the Navigation App to start, then programming the next action to close the same app will not do you any good.
To find out the types of functions a NFC Tag can be programmed with, download "NFC Task Launcher" from Google Play and click on "My Tasks".
But you can use apps to set the tag to be a toggle, right? So tap it once, it turns on navigation. Tap it again to turn it off? Or is that just for "togglable" settings like wifi on/off or bluetooth on/off?

Yes. Applications can be set to launch on one tap and close on the other. These would need to be set as two different actions when you program the nfc tag.
Wifi/Bluetooth/GPS/Mobile Data etc can be set to toggle so you don't need to create separate entries and that will spare the very little data you can write to those nfc tags.
Get Tasker. It's worth it.
You can simply program NFC tags to run a specific Task in tasker.
An example of this usage would be as such....
Get Tasker
Set NFC tag to Run "Task XXX"
Place NFC tag/sticker in Car Dock
Dock Phone to Car
NFC toggles the start of "Task XXX"
In this case... "Task XXX" may do this
Set to loud speaker mode
When receiving calls, auto speakerphone (Couple this with the Wave to answer call gesture)
When receiving texts, read out messages
Auto launch Google Maps and plot a route home
instead of me trying to explain it, i think its better you watch a few video demos on my various play lists. http://www.youtube.com/user/veryannoyingname/videos?sort=dd&tag_id=&view=1 At present there are 53 public play lists sorted by device or feature and a few more private ones which i will make public at a later date probably.
see the NFC play list and Tasker play list and home automation play lists and a few more are there in my couple of how to play lists as well. I frequently update my play lists so check them out at a later date too. Subscribers will be alerted automatically when i upload videos or update play lists.
As I understand the nfc tag is used to store data that a.nfc.phone can read.
The stored data is to issue a command such as call contact, turn wifi on ect..
--*** Be Warned ***--
!!! Always turn nfc off when you go out as I'm sure people have realised this and you might walk past a person with a nfc tag in his pocket, then your phone may start doing unwanted acts such as uploading your account data. !!!

NFC tags with over very short distances, see my video uploads on YouTube linked below.
unless the NFC tags were in the other chaps back pocket and your phone was in your trouser front pocket and you were close enough to be rubbing yourself on the other person's backside even then you would be lucky to be triggering off any such thing.
you actually demo such a hack working on another person's phone. I know there are a couple of such videos on YouTube. But seriously can anyone show a demo of such a hack working. If it did then all your credit cards that come with NFC on them now would be pillaged left right and centre by crooks and NFC tags would not come pre installed on credit and debit cards now by many major banks. Don't you think that would have tested out for such hacks on the nfc enabled credit and debit cards and NFC enabled Google phones with Google wallet features.

I dont think debit cards with nfc would be effected by what i said as you would need a device not a tag.
Im sure that someone will solve range problem, there are many malicious people out there and even if not, there are many ways to get to your phone with out you realising. day to day activitys distract you, people are not as aware as they assume.
Offtopic but slightly relavent. I've had enough time to use a script I made on phone that involves plugging in a cable.so swiping a.tag over phone while your in a cafe isn't going to be hard.
So just be warned
Things aren't always as safe as you think.

i have a tag in my car dash mount that toggles wifi and turns on my music app and then at work i have a tag on my pc to toggle wifi again and turn on silent mode. Pretty handy if you ask me rather than unlocking your phone and shuffling through it

Just ordered some NFC tags based on some of your ideas. It will be fun to screw around with at the least, and they're really cheap!

Check out the nfc play list on my channel where you will see many use case scenarios. Also check out the channel think it's called crowd gadgets on youtube who has many uploads for nfc and tasker combined use videos.
Remember, the S4 only works with a newer type of NFC tags. The old tags that advertised online to work with Galaxy S2, S3, Note 2, etc... WILL NOT work with the S4. I know because i have a bunch of them laying around the house being useless right now.
as far as I know, the new type of NFC tags that work with the S4 hasn't got release yet by Samsung. I dont know if other manufacturer made it tho.

So these tags from Amazon should work with the S4 right since its has NTAG203 chip?

Personal user, not a phone that touches a business/corporation.
Apparently the somewhat easily spoofed fingerprint reader is rated as medium security.
Encryption implements the high security profile.
Would it be theoretically possible to alter these policies? (Likely via custom ROM?)
Scenarios:
Say if perhaps Home User A desperately wants encryption and a boot password, but once at the lock screen is fine with just a fingerprint. (Particularly since most phone thieves in Home User A's area seem to turn off the phone as the first step in purloining the thing.)
Or, Home User B wishes for the same, but wants to take it a step further and at the lock screen require both a fingerprint and short password.
If theoretically possible, anyone done it yet?
Interested in whether this is possible too.
I've been playing with the settings.db according to this thread, but still have yet to find a sufficient way to do it. I'm thinking that if there's a way to alter the "security level" that each authentication method registers as, then we should be able to re-enable the fingerprint reader for encrypted devices. I'm not sure about adding a 2-factor auth method yet. I know the new NFC lock screen is supposed to be 2-factor, but I don't know how they achieved that.

This does sound promising! And I concur with your assessment.

I am vaguely familiar with NFC, but have not had occasion for usage so I am unfamiliar with this new lock screen.
I have a Note 4 with Smart Lock. I wanted to set it up so that my watch can keep my phone from locking. I added the device to SmartLock successfully. Even if my watch is sitting right next to the phone, it is not unlocking it. I use a PIN. Is there anything else that I need to do, or is this just not going to work.
Thanks
I was looking for an answer to that too. I tried and it did not work at all.
I use tasker for lots of things, but I could never get it working with this. I have a task set up to unlock the phone if the bluetooth is connected to the Gear S2. Even when my connection is just fine, tasker doesn't see the connection and never unlocks the phone.
I use Gear s2 from Tmobile with my Note 4 with no problems. When locked I use patern not pin if that makes any difference. Running lollipop 5.1.1 , no root, latest gear manager from play store.
It is added to my trusted devices
This might be a misunderstanding on my part about how this is supposed to work. I have a PIN set up, and when I have my watch connected, it doesn't require the PIN. It just puts up the screen that I have to swipe. I expected that it wouldn't put up the swipe screen at all. I don't want it to, but can't find a way around it. I tried setting up tasker to disable the lock, but it didn't work. Apparently tasker doesn't know when the watch is connected. It does work for my bt headset.
I don't think it can be done. It looks like smart lock removes requirement for any kind password but doesn't remove screen lock altogether.

If you have one of those flip cases, it does unlock automatically. Other than that, I don't know a way around it.

Same issue here. Guessing a 2 part app (specific to s2 and android) might be able to solve the problem. The s2 app would communicate with the android app (not sure if background communication is possible for s2 apps though). Upon a cut in connection, the android app would trigger the lockscreen.
Thoughts?

I've never understood the need for that. When I don't have security on my phone, I have always just shut it off. An extra swipe accomplishes nothing.
Before the gear, I was using tasker to unlock my phone when connected to my wifi and when my bluetooth headset was on. I'd carry it with me, turned on, and my phone would not lock at all. It was flawless. Never saw the lock screen and never had to enter my PIN.
I might just go back to that, as the extra screen is really annoying and serves no purpose. I just have to remember to always have my BT headset turned on and on me. I always have my watch, but always seem to forget the headset.
I wish I knew why tasker doesn't recognize the the connection to the watch. My settings clearly show that the phone is connected to the watch, so it should recognize the connection, but doesn't. I don't know how much support tasker is getting any longer. I saw something about the developer having to take a break because of medical issues. There are now many other automation apps out there. Maybe I'll give some of them a try and see if one of them will accomplish what I am able to accomplish with tasker and my wifi/bluetooth headset.
When I add the watch to SmartLock, I get the following message:
Smart Lock can't detect the security features of this device. To help protect your phone, Gear S2 (393A) will only be able to keep your phone unlocked once it's already unlocked by you. Your Gear S2 (393A) can keep your phone unlocked when it's nearby, even if someone else is holding it.
Not sure what that means or what it does to the unlocking feature.
I don't know much about tasker but one time I played with tasker plugin called trigger. Maybe that can be help for you. It is possible that tasker looking for certain Bluetooth profiles being active and since gear s2 has no speaker there is not headset or headphone profile. On my gear s2 3g Bluetooth shows call audio profile.
So on my device my NFC is disabled (It's not showing up in any menus) i dont know if its something i did (It is rooted and is using a different Firmware due to me bricking it by forgetting to unlock OEM) does anyone have an answer as to how i can re-enable this wonderful feature because i like really need it for the tags around my house (They provide networking information and i dont plan on carrying around a desktop pc to check a tag across the house in a basement). Based on where i've been looking i think a kernel is disabled or im missing drivers
Hi all,
i just got my Mi Mix 2S, great phone so far. What I miss is the possibillity to keep it unlocked when I am wearing my Garmin smart watch. With my previous phones, I could use the Smart Unlock feature, the phone would not be locked if my watch was in the vicinity. Now the Mi Mix Settings 'Unlock with bluetooth device' finds the Garmin watch (somtimes), but I cannot pair the devices. The phone prompts me to push a button on the device. With my previous phones, I did not have to push a button to set the watch as a smart unlock device.
My understanding it is a Miui restrictrion. Is this really true? Would installing a different rom support smart unlock?
Or are there workarounds (Apps, etc.) to enable Smart unlock, maybe even for trusted wifi networks?
Thanks in advance
Steffen
Global stable offered me the option to add my watch as a smartlock device but I have to disable google from the trust agents so my watch doesnt lose internet connection after a while(sounds strange, I know but it is like it is..). Actually keeping it unlocked became pretty useless with fingerprint and faceunlock(in my opinion). Maybe you get used to it too I'm pretty sure you can disable the lockscreen while connected to a specific wifi with tasker... I mean you can do anything with tasker
My Xiaomi smart watch unlocked my phone. Actually annoying, as i started dialing people from my pocket more easily.
Given fingerprint and face recognition, it's kind of pointless.
I'm on miui 10 - 8.9.20
Hi, thanks for your replies.? Face unlock works pretty well, even for my face. Will use that from now on. As described elsewhere, I had to change the region to India to make it work. Changing the region back to Germany disabled face unlock. Hope this will be fixed in future versions.
Cheers
Certain features need India as a regional setting. Its because Xiaomi want to avoid patent trolls and law suits but also want to sell their devices worldwide

Hi all, just an update how to fix the issue. I do get the notification on my smartwatch. I changed the Battery saving settings to "No restrictions" for the Garmin Connect App. It seems that this prevents the loss of connection between the smartwatch and the phone. The default setting was Energy Saving Mode. I found this tip in a German Android forum.
If your smart watch also uses an app to syncronize the data, you might want to try this tip. The menu path is Settings -> Battery and Performance -> Select app -> then choose the respective app.
The smart unlock feature only works with Xiaomi devices. Very annoying
