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.

I did some Googling and in another forum saw a poster mention that LA Metro TAP Cards use NFC. I sometimes forget my TAP card as I lighten my every day carry to a minimum as I head out at night. But I always take my phone.
Is there an app that lets you use the Nexus 5's NFC capabilities to store TAP Card fares? I Googled and searched here but didn't see too much for LA Metro. There's apps for other cities but not LA. Anyone have any thoughts or point me in the right direction?
I use the tap cards as NFC tags. I'm pondering in just buying them from my local transportation for $1 each.
NFC ReTag app let's you use them for triggers. Also let's you use them for Tasker tasks too., that means endless possibilities.
Metrolink (Los Angeles) monthly passes also uses NFC.
I'm not sure if you can use it to store fare balances though. I've never tried that and doubt that's possible.
Here's my problem: I want to be able to primitively emulate some function of a Desfire EV1 card by playing back the APDUs it receives/sends to a card reader. The problem is I don't know what kind of APDUs the reader is sending out.
I can't use KitKat because KK HCE requires the app to specify the SELECT AID APDU that the reader sends out, and I have no idea what that is or whether the reader is even sending a SELECT AID out.
I figured I could use Eddie Lee's NFCProxy on a modified build of CM9 to analyze the card/reader interactions, but every time I put my phone up to the reader, it says "invalid card."
My guess is that the reader is picking up some other NFC signal from the phone, possibly Android Beam-related. In fact, if I try to run a card emulation app on 1 phone and have another phone try to read it, both of the phones start buzzing. Even though I have Android Beam turned off, the OS's NFC scanning cycle is set to detect other Android peer-to-peer devices regardless.
Modifying the app's manifest for android.nfc.disable_beam_default doesn't disable it either.
Does anybody know what I have to modify in the CM source code to disable peer-to-peer NFC completely? Then I could build a version of CM with proper emulation. OR, does anybody have any other ideas?
I've been tearing my hair out with this one lol
I am pretty sure that every Note 12.2 Pro Verizon Wireless version will crash every 5 to 10 minutes if you have most apps open.
To fix this, you need to remove the SIM card from the tray.
Prerequisites
Must be a Verizon Wireless model
Other proposed solutions that didn't work:
Resetting the device.
Removing MicroSD.
Switching from Samsung Keyboard to Google Keyboard
Replacing/repairing the tablet (probably not a hardware issue)
Charge the battery (flickering screen fix)

This is verified to work on the Verizon Wireless Note Pro 12.2! It seems that if your SIM card has no active data plan, then this will cause their device to cause apps to crash to the home screen. Just remove the SIM card since you aren't using cellular data anyway. I don't think it is a hardware issue, but rather a firmware issue that has not been addressed and will never be for a device this old. This fix not only removed crashes that happened constantly, but it also improved app performance. Before this fix, drawing in Autodesk's Sketchbook app was a pain. Sometimes a pen/brush stroke would not appear or would delay. Similar things happened with my Lecture Notes app, causing me to believe that I may have had defective RAM (which was absolutely untrue). So please do yourself a favor and remove your inactive SIM card.
However, I don't know if a SIM card with an active Verizon Wireless data plan will also cause the Note Pro to crash. I bought it for WiFi use but it was on sale brand new for the same price as the WiFi only version. If anyone can check if the bug persists with an active SIM card with a data plan, I would appreciate that very much.

I have an active T-mobile SIM in mine and no issues so far with an active data plan.
You are right though, it did have some odd issues when I had the sim in without an active data plan.
I diddnt have any app crashes but for some reason google play would not update apps even when I was on wifi, they would just stick in downloading status.
as soon as the sim card was activated or removed they downloaded fine.
There were a few other odd blips here and there when using something with network connectivity (Browser, facebook etc.)
The only reason I could see was that if you have an inactive sim card and then go to settings > about device > status the mobile network is constantly connecting and disconnecting and switching between unknown and LTE every second or two.
I suspect this may use extra processor resources and would likely impact battery life a bit as well.
I have an inactive sim at home, I may run some tests to verify it uses extra resources.
thanks for posting this, I noticed the issues and what resolved it but did not put two and two together until reading this post.
My SIM card was an inactive verizon wireless if that helps. I've only had crashing and memory issues. It's been several months now and not a single crash, and I always use my tablet.
If you want to test on your verizon sim, you should try sketchbook, videos, and any game such as clash of clans or boom beach. You need a memory or graphic intensive app to trigger these crashes.
Any small apps like Gmail will not crash. Although I had crashes in Adobe Reader if the PDF was large or the pages had a lot of visual content.
Note that I said you will crash with most apps open, I retract that statement. It is actually more likely to crash with anything that uses a lot of memory, caches alot, or is CPU or graphics intensive
Also, I think this bug only occurs on Android version 5.1.1
No problems here
Just wanted to let you know that I am still using my Note Pro with an active Sim card and I'm not running into any reboot issues. (I still haven't found anything even comparable to it to upgrade to without crossing over so i'll just keep using it! )
a few weeks ago I purchased a Cycling specific computer, the Hammerhead Karoo 2. Its running oreo 8.1. has 32Gb memory, BT, ant+ , wifi , and a sim slot for cellular data. to save memory it ships without google play services so any apps need to be side loaded.
beacuse this is basically a smart phone without the phone app( there no mike nor spearker either but BT could be used) my goal is to be able to use this while out riding, in case of emergency, and not have to take my phone with me as well.
What apps would be needed to have text messaging available? what do i need for MMS service? and suggestions for a one button SOS text app would be nice.
Thanks
