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
[Galaxy S 4 Accessories] rtmeikle:
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!
[Galaxy S 4 Accessories] bubblesmoney:
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.
[Galaxy S 4 Accessories] xxlikquidxx:
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.
[Galaxy S 4 Accessories] jax5ter:
these are the cheapest i found that are non samsung tags and they have the NTAG203 that works with the S4 i use the tags ordered from here daily with no issues.

[Galaxy S 4 Accessories] xxlikquidxx:
So these tags from Amazon should work with the S4 right since its has NTAG203 chip?

http://www.amazon.com/TagsForDroid-...=merchant-items&ie=UTF8&qid=1370458262&sr=1-4
[Galaxy S 4 Accessories] jax5ter:
yup pretty much any tag that claims its NTAG203 should work with our S4's. And the one amazon are the same ones from my link.
[Galaxy S 4 Accessories] verbuyst:
Thanks dj_aj, just bought 5 from ebay. Gonna have some fun when I get them
[Galaxy S 4 Accessories] Nizda1:
Download the app "NFC Task Launcher", they have really cheap tags you can buy through the app starting at 3.99 for 5 tags. Best deal is really there dev pack 21 tags for 20$. The S4 can use any NFC Forum Type tag 1-4, type 2 seems the most available. Main difference between the types are that they scale in size from 1-4, 4 being able to hold the most data. As someone suggested tasker & nfc can achieve some very cool stuff, but a lot of nfc apps now seem to have a simplified UI with built in profiles/locales, for example you use your car tag and amongst the commands is a locale tag that will turn your wifi off when your x distance from your home and will then turn it back on again when you get into whatever range back home, without even needing to touch the tag again. Now if you really want to get some use out of it and you don't have a writer, check out what asus just came out with. Very cool how they are bundling it with some of there new z87 boards.

[Galaxy S 4 Accessories] Streetking21:
I set up a lot of NFC Tags in my house. Here are some examples:

1) When I come home I can choose between 6 actions, i.e. turn on the PC (by WOL), start a light scene or turn on all the lights in a specific room. When I leave, I have a tag that shuts down my PC and turn all the lights in my home. I made some more tags to combibe different actions.

In my personal training room I placed a tag that turns on the power supply for the speakers and a Bluetooth receiver there. Then it turns on Bluetooth and connects to the receiver, starts playing music and raises the volume to max.

When I touch the tag again, music stops playing, Bluetooth turns off and the power for the speakers and the receiver is turned off.

I also have a tag on my car's docking station that turns on GPS disables lockscreen and starts navigation.

I use a couple of tags at my bed where I programmed different wakeup tomes for my alarm app so I can easily decide when to wake up on a daily basis.

I can post some pictures of the set up if you want.
[Galaxy S 4 Accessories] jax5ter:
what are you using for the lights? Are your lights hooked up to your wifi network? i want more info about that, been trying to setup something like this for myself so been researching.
[Galaxy S 4 Accessories] Streetking21:
I use the system Light-Manager of the company JBMedia (http://cms.jbmedia.de/) which is able to send radio signal to specific socket (with dimmer). It normally receives the command from an infrared remote (like the Logitech Harmony One) or via a the software Lightman Studio by USB. That software has a small webserver included but as it is Windows based, it only works when the PC ist on.

Therefore I recently bought the Wifi Bridge which is a seperate device to set up a standalone webserver specifically to control my Light-Manager Mini. It receives the command by http request and can process parameters for light settings and actors. It then sends out the corresponding infrared signal to the Lightmanager Mini.

Additionally I use a dyndns account to control everything by any place.

You will find some pictures of the system, software and my implementation attached.

First picture shows the Light-Manager Mini (left) and the Wifi Bridge (right), both indicate their status with an led, the small button of the Light-Manager Mini is used to set up 2 "shortcuts", long and short press activate a specified scene.

The other pictures show different applications for NFC tags. I decided to give any tag a pictogram to make it more intuitive. Then I laminated it and used Sellotape to keep in in place from the back side. (side note: the nfc tags are adhesive but I want to be able to reuse them, i.e. when I change the layout of the pictogram sheet)
[Galaxy S 4 Accessories] jax5ter:
awesome info on the lights, thanks!
[Galaxy S 4 Accessories] hollywoodfrodo:
I'll second using Tasker with NFC Tags as a way to give you the most options. There's also an app called "AutomateIt" which is kind of "tasker for dummies" and can be triggered with NFC Tags. Otherwise, for straight NFC Apps, NFC Smart Q is good as is NFC Task Launcher which was mentioned before.

With the S4, it's best to stick to Type1 and Type2 tags. As mentioned NTAG203 Tags will be adequate for most task triggering apps and are compatible. If you need more memory (maybe you want to create a Vcard tag to use as your business card) then the Topaz 512 Tags are good tags because they have about 450 bytes of memory and are compatible with the S4 (as well as any other NFC Device since you'll be wanting to share that Vcard info with others).

The only limitation to what you can do with NFC Tags is really based on your imagination and tech savvy.
[Galaxy S 4 Accessories] JonBsbB:
I have done some searching and cant seem to find answer. Can you set up an NFC Tag to power off your phone?
[Galaxy S 4 Accessories] Caferacer:
I have a tag in my wallet. If I tap my phone to it it opens up mint on my phone.
[Galaxy S 4 Accessories] Streetking21:
Yes, start a Tasker task with nfc task launcher. With Tasker you can shutdown the phone. You will probably need root access for this.
[Galaxy S 4 Accessories] poisonsushi319:
Hi,

I just thought of an idea and would like to see if NFC tags are good for this.

I volunteer at a family clinic and notice that a lot of time are spent on finding a patient's folder, we have maybe 6000 folders. Would tagging the folders with a NFC tag be applicable in this sense? One would just have to wave the phone slowly to see if a patient's folder were looking for is in that stack/shelf.

Thanks,
[Galaxy S 4 Accessories] jaepoori:
i dont think it would be cost effective seeing how much nfc tags go for. 6000 folders would be $6000+. Just saying
[Galaxy S 4 Accessories] scott14719:
Unless you didn't use 1 tag per folder. Depending on how many folders there are total, NFC could be used to separate the folders into groups of 50 or 100. That way, you could localize the search and look through 50 or 100 folders to find one instead of looking through 10,000 folders to find one. Of course, a simple bar code system would achieve the same thing for a lot less.
[Galaxy S 4 Accessories] Streetking21:
Totally not applicable and completely senseless in my opinion. Lets say you have 6.000 folders and lets say 60 shelves with 100 folders each. You really want to scan 60 NFC tags to know if a specific folder is in one shelve?

There is something called 'alphabet' that you can use for this scenario. ;)
[Galaxy S 4 Accessories] splitroaster:
Ok got some tags and heres what im wanting to

play music

Turn up volume

switch on bluetooth

connect to radio

well it goes ok till connect to radio but found an app called auto connect so going to try that tomorrow and see if that helps im using nfc task manager
[Galaxy S 4 Accessories] hobbiwan:
1 tag for multiple phones

Hello,

OK, thanks to everyone for the examples on how to use NFC tags.

I especially like the images from Streetking21 which explains it all!

I understand that the app writes some kind of data to the tag.

When the tag is read, then the actions are done on the phone.

However, I have a need that goes to the opposite of this use.

I want to put a tag on my front door for example and when I get home

* my phone turns WiFi on, turn BT off, and set ringtone volume to max.

* my professional phone to turn Airplane Mode on and ringtone to vibrate

* my wife phone to turn WiFi on, BT on

* my child's phone to turn WiFi on, launch Facebook

etc...

The actions depend on every phone's configuration, not on the tag.

Can this be achieved using a single tag, or do I need a tag for each phone in the house?

I imagine there must be an application that can read the tag's unique ID and trigger actions/configurations based on that. Any idea ?

Thanks!
[Galaxy S 4 Accessories] thunderwolf17:
I would think that you could do this with Tasker being installed on each device. What you would do is create a Tasker task called "Home" on each device. Although the name of the task needs to be the same on each device, you can define the task to run different actions. So, on your phone, you would define the "Home" task to turn wifi on, bt off, and ringer loud. On your wife's phone, you would define the "Home" task to turn wifi on and bt on.

In this scenario, the NFC tag is programmed to simply execute the Tasker task that is called "Home" regardless of which phone scans it. The drawback is that you would need to purchase a copy of Tasker for each google account (looks like 3 or 4 for you). On the other hand, it is an incredibly powerful app for which you will undoubtedly find many other uses.
[Galaxy S 4 Accessories] orateam:
Got the TagsforDroid version from amazon. http://www.amazon.com/gp/product/B00DZZB5U6/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Sadly, they did not work. They work great on nexus 4 and from what i understood, the S4 should work with NTAG203. wierd. I'm wondering if my ROM, Hyperdrive possibly changed things enough to be the issue?
[Galaxy S 4 Accessories] hobbiwan:
Thank you thunderwolf17. I will give this a try.

NFC Tag for laundry timer

I put a tag above the washing machine, and another above the dryer. It sets a timer to remind me when laundry is done.

---------- Post added at 02:27 PM ---------- Previous post was at 02:22 PM ----------

Tags can also be good for medications. For example, you only take cough medicine as needed. So after the first dose, I set a 4-hour timer that tells me when the next dose can be taken. You don't have to take it, but you'll know that you're free to take another at any time.

It's easier than using a medication management app.
[Galaxy S 4 Accessories] wifiuk:
i have a NFC tag in my dash that turns on Driving Mode, enables S voice and turn on Bluetooth, And says Car Mode On then tap it again and turns all the things back off and says Car mode off.

I have a NFC tag by my bed that puts my phone into Silent mode and opens up a streaming music app and says Night Mode, then tap again it says Day mode and puts everything back to how i normally have my phone during the day.

I have a load of others, but havnt found a use for them yet, need to think up some inventive ways to use them
[Galaxy S 4 Accessories] jproy12:
Just got my tags, and this thread is giving me some good ideas!
[Galaxy S 4 Accessories] jasondreher:
How do you set a timer?

I have been trying to set a timer on a NFC tag for a while now, and I cannot get it right. When I use NFC Task Launcher there is no notification when the timer is done. How did you set yours up?
[Galaxy S 4 Accessories] ChaoticUnreality:
Okay so I read this thread thinking of buying some tags but wanted to make sure that the only thing I would need in order to use them would be my phone. I don't need another dongle for my computer to program them the first time?
[Galaxy S 4 Accessories] jproy12:
Nope, just your tags and your phone, you'll need to get an app to manage the tags for example NFC Task Launcher.
[Galaxy S 4 Accessories] ChaoticUnreality:
Thanks I got the NFC task launcher app but I will most likely be making the tasks in Tasker. Is there anyway to cut out the NFC Task Launcher App and just get Tasker to trigger directly?
[Galaxy S 4 Accessories] Streetking21:
Sadly, no.
[Galaxy S 4 Accessories] billias:
I am not going to tell you, what can you do....

I will give you an Idea what i do.

Using some nice app, like tasker I achieved to:

Simple tasks:

Docking phone to my car.

My bluetooth starts

My Player stops

If i am connected to my house wifi, (and time is between 6 in the morning and 13:00) all the lights goes off on the house.

Heating of my home goes to 17 degrees celc.

Outside my house

It is night and i cannot find the lock... just touch the nfc tag and the light goes on for 10 minutes

Immediately after 10 seconds my hall and living room are lighting up. My stereo starts at low volume with my favorite radio station.

2 extra Tags next to my stairwell (upper floor)

Green Tag: = Go to bed

Stairwell lighting on

5sec after, bathroom light on for 20 minutes

10 minutes after bedroom light 50% for 15 minutes, then 25% for 3 minutes and then off

1 minute after everything is executed all the house lights goes off (just in case i forgot something).

My bed radio is also on again for half hours, it goes on with the bedroom light.

Temperature is set 15degrees for the whole house and 19 for my bedroom until next morning.

Yellow Tag: Bathroom only

Stairwell light on

Bathroom light on and bathroom heating on 20C

30minutes after the light goes off, and heating to it's previous state.

I am still building and modifying my automation, but till now this is what happens with my place.
[Galaxy S 4 Accessories] jetpack101:
I have a tag by my bed that puts screen into Auto, turns the phone to silent and turns alarm on.

I also have one by the front door that turns WIFI on and off as

you come in and out. One on the dash to turn on maps and driving mode.

They can do lots of things.
[Galaxy S 4 Accessories] powerarmor:
Guys, why is that some people write that it is not possible for the tags to perform 2 actions (eg. 1 tap turns airplane mode on, second tap turns it off), and others say that they use it that way?

Do I need two tags in my car to turn gps on/off or one is enough?

Can someone confirm this?

Thanks.
[Galaxy S 4 Accessories] jetpack101:
One is enough, when setting up the tags you can choose the toggle setting. This means that you have the first command turn WiFi on and the second command turns it of. Every time you touch the tag it will cycle the commands for each touch.
[Galaxy S 4 Accessories] Tlab56:
I met a guy who had NFC business cards so all I had to do to get his contact info was tap my phone to his card and it populated in anew contact field for me. Very cool!
[Galaxy S 4 Accessories] brian999:
Can you use NFC Tags to find something near you? Such as if I stuck one on my TV Remote Control?
[Galaxy S 4 Accessories] kasakato:
Unfortunately not. The distance is essentially nothing.
[Galaxy S 4 Accessories] hollywoodfrodo:
AutomateIt would be good for this since it just uses the tags UID to trigger things on the phone so each phone could use the app with the same tag to trigger something different. Also, Llama is a free app which is kinda like Tasker and has the option to write to the tag OR use tag's UID so could be used in the same way.

---------- Post added at 06:20 AM ---------- Previous post was at 06:17 AM ----------

Many apps like Trigger and NFC Smart Q allow you to create "toggle tags". However, with Tasker you can create even more complex tags. For example I have a tag by my bed. If I tap that tag between 8pm and 3am, it sets my phone to night settings and opens my alarm app. If I tap it between 4am and 10am it sets my phone for day time settings. If I accidentally tap it any other time it does nothing.

Also with the all Llama you can use location triggers paired with an NFC Tag so that, for example, an NFC Tag in your car could trigger different task depending on where you are when you tap it. I have a video demonstrating this on my youtube channel.

Pairing NFC Tags with Tasker and/or Llama allows super cool things.
[Galaxy S 4 Accessories] Ampsy:
Hi All,

I've got a few NFC tags, and although my phone is an S3, it's pretty much the same with regard to software etc.

I have written tags to open web pages, apps etc, but the one thing I really want to do is turn off/on or toggle mobile data.

The object is to turn it off when I go to bed so it doesn't waste battery overnight, although drain is approx 1% per hour when idle.

I did have a tasker task running for starting google music when headphones are plugged in, but that made my battery drain much faster so I'd rather not use it.

Does anyone have any ideas how this could be done?

Phone is rooted running ArchiDroid KitKat ROM.

Many thanks in advance,

Chris.

[Sprint Samsung Galaxy S III] edufur:
I have been having this annoying problem since day 1 and cannot get an answer to it. Even google has failed me. So, whenever I choose app defaults (like launcher or different sms app, etc) they stick as defaults until I reboot. When I reboot, it asks me again for each one. I have this same problem whether I am rooted or not, have had it with stock roms, etc. Why is this happening? It is very frustrating.
[Sprint Samsung Galaxy S III] edufur:
Wow... no one else is having this problem? Should I return it for exchange? It seems like a software glitch, but a factory reset doesn't fix it.
[Sprint Samsung Galaxy S III] edufur:
Still having this issue. Is no one else having it? Are there file permissions I can check? Is there a file not properly getting saved which holds defaults? I hate having to constantly remind my phone which apps to use for what.
[Sprint Samsung Galaxy S III] prboy1969:
What Rom are you on ? Are you doing a Clean Install ?
[Sprint Samsung Galaxy S III] edufur:
As I stated in the OP, on every ROM, rooted or not. I have done a wipe with every ROM I have used. Even occurs when I do a factory reset with a stock rom. Fix permissions does not help either.

I have a sneaking suspicion that there is no such thing as a full factory reset.
[Sprint Samsung Galaxy S III] topherk:
Did you try wiping /system prior to flashing the various ROMs? Typically when someone does a factory reset, it means they are clearing /data and the caches. It sounds to me like something is messed up in your /system partition, which might be persistent across ROMs.
[Sprint Samsung Galaxy S III] edufur:
Yes... full wipe before each rom... and full wipes after factory resets.
[Sprint Samsung Galaxy S III] edufur:
does anyone know which file is responsible for storing app defaults? I'd like to take a look and see if it is getting overwritten, or what the deal might be. This is an annoying problem. Having to keep selecting my video player, launcher, etc.
[Sprint Samsung Galaxy S III] prboy1969:
By " Full Wipes " . Do you mean you wiped System, Data, Cache, Dalvik, and a Factory Reset ?
[Sprint Samsung Galaxy S III] edufur:
Yes... e-v-e-r-y-t-h-i-n-g

I have fully wiped (yes all of it) prior to a stock rom install... and factory reset plus fully wiped (yes all of it) after a stock rom install.

yes... wiped to the point of losing ALL- ALL--ALL data. I have taken this thing down clean.

I have one-clicked, standard odin'd, kies, dialer pad reset, recovery mode reset, settings reset....

Every time... I am able to get back to stock clean... but nothing is resolving to the point where app defaults will start behaving. They arent behaving.

I lose them after every reboot.
[Sprint Samsung Galaxy S III] knishknosh:
app defaults not sticking on reboot

I am also having this problem on my Sprint SGS3 (not rooted).
[Sprint Samsung Galaxy S III] prboy1969:
Can you post a Screen Shot of the Pop Up you see when the issue occurs ?
[Sprint Samsung Galaxy S III] edufur:
I don't understand why you need that. KnishKnosh understands what the issue is. Are you not understanding what I am describing?

Surely you have seen this phenomenon before. Whenever there are multiple apps to accomplish a task (i.e. browsing, launching, texting, etc), it will ask you which app you want to use. You then choose an app and tell it to always use it or to use it just once. What I am saying is that even when I choose "always," it only sticks until I reboot.... then it asks again. This is not normal behavior.
[Sprint Samsung Galaxy S III] Spark91:
I have the same issue as well Edufur, So you're not alone.

Usually my problem is Home Launchers not sticking on reboot.

And coincidentally its all the home launcher apps i paid for pro excluding Holo Launcher and Nova.

Apex Pro, LauncherPro+, ADWLauncher Ex are the ones for me that always resets its default status for being home.

There's a lot of people that has this problem and there hasn't been a fix for it.

Its more like a Device Compatibility issue for certain applications to me then anything else.

Because my friends LG OG doesn't have these issues.
[Sprint Samsung Galaxy S III] prboy1969:
I want to see your issue resolved. That is why I am asking all the questions, and for more information. I do not have the Device in front of me. So I must ask questions in order to help track down the issue. Yes I have seen the issue before. Spark91 brings up an interesting question. Are you using the Stock TW Launcher, or a different one ?
[Sprint Samsung Galaxy S III] knishknosh:
i uploaded scrernshot. hope it helps. thanks.
[Sprint Samsung Galaxy S III] prboy1969:
First thing is please edit that pic ;) . So you Tap Always and after a Reboot it just asks again ? Has it always been that way ? You mentioned it was only on certain Launchers. Does it do the same thing on the TouchWiz Launcher ?
