It is great that the functions are stored on the tags rather than the device using NFC task launcher but is there a way to pull them from the tag to modify existing tags, or to backup the tags you created so that when changing ROMs and such, you still have all your tags.
[Samsung Galaxy Nexus] flame10:
I am still new to this NFC thing, and to be honest I don't yet have any NFC tags.. but I automate most of the things using tasker (I use Mobile Towers instead of NFC).

However here's a good idea which I couldn't find from anybody.

1. Attach a NFC tag to my BT headset.

2. Switch on BT and select that device.

3. Switch off BT when tapped again

Best thing about this is, Its best to attach different NFC tags to different Bluetooth devices (like I have a creative D100 & also a MW600 and a Jabra Halo)

PS. I don't yet have any NFC tags.. so cannot try these yet..
[Samsung Galaxy Nexus] Airax:
Or just leave BT on? Seriously I leave BT on these days on all my phones and it doesn't have an appreciable impact on battery life.
[Samsung Galaxy Nexus] Evostance:
As you said, the information is stored on the tag. So when you have a new rom, just install NFC task launcher and it should know what to do.

Alternatively, use titanium backup
[Samsung Galaxy Nexus] Ammontj:
Of course right after I I was looking for this functionality, I installed the latest version which allows importing tags
[Samsung Galaxy Nexus] nerys71:
the only real annoyance I have with it is that task launcher won't let you EDIT a tag (that you already have saved) you have to delete and REMAKE the action. you can't just edit it.

Have you tried the "Wifi QR Generator" app for that?

/I realize this is ancient, but I didn't see a direct response to that comment in the next 50 or so responses, so thought I would point it out.
[Samsung Galaxy Nexus] AndyCr15:
Automatically connecting to WiFi networks is the main use of tags for me. One by the front door of my house so people can connect to my home network. One on my GoPro 3 to turn WiFi on and connect to the GoPro. One on a mobile router to do the same thing.
[Samsung Galaxy Nexus] nerys71:
so I understand how to use tags to turn wifi on and off how do you stipulate "WHAT" it connects too when you do this?

as far as tasker. eventually I don't see why you can't put the actual tasker instructions "INSIDE" the tag (you do have 768bytes as your disposal) so tasker function "BECOME" as universal phone to phone as any other function so long as tasker is installed.

I am still trying to get someone to "fix" the nfc.apk for the Note II so it works screen off. I found one but it fails. it works on lock screen but not screen off.
[Samsung Galaxy Nexus] AndyCr15:
NFC Task Launcher lets me write it into the tag.

[Samsung Galaxy Nexus] nerys71:
oh I have that. so if I set up a wifi something will pop up telling me how to configure it ? (all my networks are open networks but sometimes I access closed networks)
[Samsung Galaxy Nexus] AndyCr15:
No, in the app you tell it the name of the network to connect to. If they're already open, I can't see it saving much time to be honest...
[Samsung Galaxy Nexus] nerys71:
obviously its not needed for open networks I was just curious "how it worked" for closed networks.
[Samsung Galaxy Nexus] thelastwilson:
I think that is because most people don't want to deal with the security implications of always on/available nfc connections.

[Samsung Galaxy Nexus] ab_ndev:
Authentication in NFC tags

This seems very interesting. I'm a student and new on xda forums. I recently developed a project which I put on the app store.

You can search for N-Tap on the google app store

(This is my first ever android app and I'm looking to add more features to it so any suggestions are welcome :D)

I've been searching for a while on xda forums for ways to add a sort of Authentication system so if the user wants he can actually

write private data to the tag and only certain users with the a authentication key can access it. Is there a way to do that ?

I know I can make tags Read Only but that doesn't solve my authentication problem. It would be great if the tags could not be actually overwritten or accessed without a authorized key.
[Samsung Galaxy Nexus] julllleee:
Is it possible to take a card, eg my bus card and place it on the back of my phone and the gnex copy that. And then when im riding the bus can i place the gnex on the machine and make it do the bus card it copied? :)
[Samsung Galaxy Nexus] thelastwilson:
I maybe influenced by working in IT and having to think about security a lot more then most people. Generally any "NFC" exploit involves using NFC to send the phone to a website that has an exploit. If you can't do this without unlocking the phone then it's much harder to do this without user/owner action.
[Samsung Galaxy Nexus] elliott9:
Another use for NFC

It took a bit of finagling but if you have an NFC device and an Onkyo receiver you can setup the following.

Place an NFC tag on the inside of an lamp shade next to your couch (or multiple)

Use NFC Task Launcher to launch a Tasker Task when scanned

Use the Tasker plugin AutoShortcut to launch App Shortcuts in your Tasker Task

Install the app OnkyTroller setup the settings needed to connect to your receiver.

Link the Tasker shortcut to Onkytroller shortcuts

I have a few NFC Tags on my lamp shade. I can Turn on the receiver, switch to various inputs and turn it off. Those were the only things I ever used the Onkyo remote for so now I can just throw that in a drawer and free up a little bit of space on my end table.

Also I have some speakers connected to Zone2 in my garage. I have a feature request in to the developer of Onkytroller to add shortcuts for Zone2. Then I could have a tag in my garage and when I scan it have the receiver power on and start playing Pandora in Zone2. :cyclops:

[Samsung Galaxy Nexus] jpalo:
I use Tasker for the same. Only that it's without NFC and only looks for specific WiFi connection to send WOL. I then have Lights-Out plugin on my WS2012e to keep server up and running for as long as I'm home. After 10 mins of me leaving the house LO puts the server to sleep. Same happens at night when I put the phone to charger, Tasker shuts down WiFi and server sleeps before I do :)
[Samsung Galaxy Nexus] martyh1:
Still haven't gotten my tags but I use Big Font a lot to change the font size, example, a larger font in car. Does anyone know if there's a way to do that with a NFC tag?
[Samsung Galaxy Nexus] martyh1:
Nevermind. This can be done with the tasker plugin, secure settings. And obviously, any tasker task can be executed by NFC Task Launcher.
[Samsung Galaxy Nexus] damocles:
I got one tag attached next to my seat in which I game. I only play Black Ops 2 with some friends. So I installed an NFC tag which sends my friends a message (SMS) to let them know I am going to hop on the PS3. And I have got the standard stuff. One in my car with a swith for bluetooth and some other tasks. And next to my bed as well turn on/off data turn off sound turn on alarm etc.

Oh and I found a pretty cheap supplier on eBay for NFC tags in Europe.

[APP][NFC] Badge NFC: use your phone as clock in/out card

:rolleyes:
[Samsung Galaxy Nexus] awaldeck:
I have an idea: tap a nfc tag when lets say you have a youtube video playing on your phone, and you want to share it to your upnp media centre/tv

Currently you can play the video , tap the share button, choose the app and depending on the app you click ok or it does this.

Now what I cannot get to work is to do that share -> app -> action

to work

I open the app with the nfc tag but it doesnt do the action.

Any ideas?
[Samsung Galaxy Nexus] fackamato:
Hm. I had llama format an NFC tag, and put it in a profile /event so stuff should be done. But Whenever I can the NFC I just get a popup "NFC Tag found: name-of-tag", and that's it.

What's wrong?

Tasker vs Tags

That is exactly the use I was thinking for the tags, and I have the same frustration that you have to switch the screen on for the tag to work. Tasker, on the other hand automates everything brilliantly, eg night mode (silent but allowing VIP calls, dim screen etc) works on mine between 11pm and 7am if connected to a mains charger, office mode (silent) starts at 8:30am workdays where I don't have a holiday or bank holiday in my calendar, car mode switches on when my phone connects to my car's bluetooth and will switch off office mode if it's on. The car mode especially is much better done by tasker as I don't need to take my phone out of my pocket, but all of them require nothing from me other than to keep my calendar up to date (which I've always done for years anyway) or plug my phone in at night.

I can see a good use for them at work as inventory control for fixed assets, but I'm still struggling otherwise to find a use for them other than the fact that I have some tags that I'd like to use.
[Samsung Galaxy Nexus] Schiehallion:
My 2 tags I use are the first one by the front door that is coming in/going out type (GPS on/off, WiFi on/off etc). Can use screen off with mod for cm nightly I run. Second tag fires up playlist 1 in Google music on the way to bedroom at night
[Samsung Galaxy Nexus] bombadier:
I carry an NFC tag in my wallet and with the help of tasker have it set PIN Lock/Unlock,also helps that the ROM I use has a silent vibrate mod with the NFC reader,I don't normally want a PIN lock but if I am on a night out then I can easily lock it down by touching my phone to my wallet.
[Samsung Galaxy Nexus] actd:
Without rooting the phone (which I'm reluctant to do with a new phone), it's still limited - the idea of having tags to switch on/off a 'home' mode as you go through the front door still seems to me that you have to remember to do this (and assumes you don't have your hands full) - whereas having it simply recognise your home wi-fi on tasker would, again, mean you don't have to take the phone out to achieve this.

I suspect I may end up using my tags as stick on ID tags for valuable items - cameras etc.

Of course the problem may be not that the tags aren't useful, but more that Tasker is just so powerful. The NFC tags may find more uses on Windows and iPhones where tasker isn't an option.
[Samsung Galaxy Nexus] Ammontj:
Personally, I find the combination of the two to be the most useful. I have setup tasker to turn Wi-Fi on when I'm connected to any of the towers near my house so I connect to my Wi-Fi, and off when I leave. But then I use NFC Task Launcher to check me in on foursquare to my home once I connect to my Wi-Fi (it does this through the Wi-Fi trigger vice a tag)

What I use tags most for is at locations to check-in to foursquare, and enable Wi-Fi at other places, whet its a coffee shop I frequent or the gym, if it's in a place others can use then it would perform the same action for anyone. Then the one at the gym launches the music app for me as well. I use one to toggle my Wi-Fi tether on and off that is stuck on my laptop so if I need to connect on the go I can easily and turn it off quick so not to burn too much data.

All of this is possible without root, though I am rooted. Hope this helps with some ideas. I have use for both without a doubt. You can also use an app called InstaWiFi, to save your router login info to a tag (or you can use it to create a QR code rather than a tag, I have both). I use this to allow friends or family to access my Wi-Fi without having to give them the password.

If you were to choose to root, then you can do much more. I like having one on my night stand that turns the volumes down, brightness down, starts desk dock to display the clock, and disables my lock screen. All of that can be done without root, except disabling the lock screen. It would be rather complicated to set this up with tasker alone since I work rotating shift work that changes every 7 days. Setting the schedule in tasker would take far too much effort in comparison to the tag that does this.

Touch and Tether

I've been using NFC tags for only two weeks. Most of what I use them for is already listed here, but I have one use that nobody has mentioned. I put a tag on my notebook computer next to the touchpad. When I am traveling with my computer, I often need to tether to my cell phone for Internet access. Touching my phone to the tag puts my cell phone in WiFi tether mode. My computer then automatically sees the access point come online and connects to it, giving me Internet access.
[Samsung Galaxy Nexus] achaia40:
Can I set up a tag to use as a business card. Leave it with my contact information or even be able to let a client just swipe a tag to send me a specific email or message to myself from their tag.

Looking for a way to use it for advertising or customer support.
[Samsung Galaxy Nexus] bassie1995:
I think you can. Check out NFC Tag Launcher (I think) in the Play Store.

[Samsung Galaxy Nexus] Ammontj:
NFC writer by tagstand will work for some really basic features such as contacts or websites. For additional functionality NFC task launcher it's what you're looking for.

I think that NFC writer will allow you to write a tag that doesn't require the user to have a specific app installed to run it so that may be what you're looking for (I'll have to find my blank tags and test). For more automation for yourself, you would use NFC task launcher.

Musician/Recording Studio Ideas

I'm a musician/engineer/producer and tossed an NFC tag on my guitar case, tap it, and metronome app starts up for practicing. Could also use for a tuner app, or put a tag in various places in the studio like next to your console to start up your DAW software (I use TouchDAW). Studio managers could make various charts (sheet music, time logs, lyric sheets) readily available to clients using the web, NFC and strategic placement of tags. There's about a billion uses I could think of to make life easier in the studio.

[Samsung Galaxy Nexus] incredulous:
Stupid question, but I am going to buy 10 tags. I want to know, are the tags rewritable?

I mean once I write it am I stuck with whats on it or can I alter its use?
[Samsung Galaxy Nexus] Tubes6al4v:
It depends on the tag. Most can be overwritten, but only some can be locked into "read only" mode.
[Samsung Galaxy Nexus] Antzor:
The ones I bought from tagstand are rewritable
[Samsung Galaxy Nexus] hcgl:
I see different size stickers, like 1k, 277bytes and so on :) For normal uses like the ones you talk about here, what would be the smartest size? :)
[Samsung Galaxy Nexus] DroidSloth:
Most of the tasks I've set up in NFC Task Launcher are in the 60-80byte range. a vCard needs more, about 200bytes, so it depends on what you want to do, but the basic 144 should meet most needs unless you want to store crazy stuff in there.

Can anyone tell me if using the NFC launcher software...can you use tags to unlock your phone?

Example. You password lock your phone. Alternative way of unlocking would be the nfc tag (lets say the tag is in your wallet, you swipe your phone over your pocket).

Not saying this would be feasible for most people, but it'd be a cool parlor trick! lol
[Samsung Galaxy Nexus] JayBeezy802:
For the NFC app, like this one the screen must be on for it to read the tag; i.e. the phone must be in an active state. You do not have to actually open up the app per-say but the screen must be on.
[Samsung Galaxy Nexus] akellar:
Yeah like the last guy said, screen on and unlocked or nfc doesn't work. Not an app limitation, it's the hardware/software of the phone.

[Samsung Galaxy Nexus] CBMC:
Also note that the small 25mm circle ones and the small waterproof ones don't work as well as the 35mm square tags (our bigger). They aren't quite strong enough, though you can get them to work, just takes putting the phone exactly in the right spot. The bigger ones are much more forgiving. Personally, the classic 1k work great. As others have mentioned, buy NDEF pre-formatted if you aren't on 4.0.3, since earlier versions of ics wouldn't format blank tags.
[Samsung Galaxy Nexus] robby88:
Ok guys seriously, almost no one is suggesting what to do with the NFC tags. Please stop asking questions and posting nonsense. If you need to ask questions about NFC tags go look for a thread with the correct info.

I just got my tags and I'm making a car settings one and the alarm one. I wanna come up with other stuff, maybe more complicated tasks combining the NFC tags with the Z-wave ( http://www.asihome.com/ASIshop/prod...=3318&osCsid=54225be577a2df67116fc6fc6864d998 ) to do lights and door locks.

This is the app you could use ( http://melloware.com/products/zwave/ ), but I'm not sure how to get the tags to send those commands. Would I be able to set up a Tasker setting to do it? I've never really used Tasker, but from what I've seen its highly in depth. Anyone know if something like that would be possible?
[Samsung Galaxy Nexus] akellar:
You mad bro? Take a deep breath. It's not your thread and your not a mod. People asking questions isn't hindering you in anyway. Relax.

To tell you what I do with tags (since it apparently is your requirement for posting in this thread); I have one at my door that on tap 1 - turns on wifi and turns down volume. On tap 2 - turns off wifi and turns volume up. I also have one in my car that turns media audio volume up and starts Pandora.

So with that said how about we try and get back on track...once again...
[Samsung Galaxy Nexus] ellesshoo:
I'm considering undertaking the door thing but I just don't have enough time at the moment to devote to it. Without really thinking it through in detail and investigating what products are out there I'm thinking I'll need first and foremost a way to mechanically unlock the door. I think the best solution, again without searching for odd new products, an AC or DC powered door strike. This would be cool because when you "unlock" you could simply push/pull your door since electric strikes actually move out of the way of the latch, you wouldn't even need to twist the door knob and you probably wouldn't even have to change the existing knob/lock hardware on the door side. Another nice thing is they are fail-secure so if the strike lost power your house wouldn't be sitting unsecured for anyone to walk right in. Also, with or without power, in an emergency or a situation where you didn't have your phone, you could operate the door exactly like you do now with a normal key.

The tricky part would be signaling from the nfc in the phone (or even just using an nfc token) to the door strike. Again, my initial and unresearched thought would be a USB nfc reader coupled with some kind of easily programmable logic board like an Arduino or any prototyping board. An Arduino should be able to handle communication to an nfc reader and can certainly handle turning the door strike on/off. All this should make it easy to tie into any existing home automation software/controller as well if you have something installed already or may want to in the future.

It would sure make things easier if there are some products out there that are either designed for this exact purpose or at least for handling a portion of the steps (ie. Nfc reader with integrated outputs or door strike power supply with integrated signalling inputs). Wouldn't shock me if stuff like that does exist
[Samsung Galaxy Nexus] ellesshoo:
Even if tasker doesn't have a purpose built interface in to the zwave app it's quite possible it could use some more crude way of passing the tag data via action/component intents or simulated key pressing. Do you know any more details about that zwave thing?
[Samsung Galaxy Nexus] bethanensinger:
I just got my NFC tags today so I setup one for my car dock to launch spotify and bluetooth and turn off wifi, but I am wondering if there is a way for me to also have it send a text message when I get in the car letting someone know that I am leaving. Is there a way to program this in tasker? .
[Samsung Galaxy Nexus] Cheesejam:
Can you make a tag that not only opens an app, but does something on it too? For example, I have this running app that tracks my runs. So, I want to have a tag in my armband holder that opens the app and presses the button to start the tracking for my run. Is this possible?
[Samsung Galaxy Nexus] SwiftLegend:
That's actually a really cool idea, and I'd love to see this :P
[Samsung Galaxy Nexus] ellesshoo:
Yes, tasker could easily do it
[Samsung Galaxy Nexus] ellesshoo:
You could definitely use tasker to launch the app. Starting the tracker could be possible if the app accepts has an intent for starting that activity or better yet, tasker 3rd party support or a tasker plugin. If the "start" button is right there when you launch the app you might be able to get away with having tasker simulate a button press.
[Samsung Galaxy Nexus] Cheesejam:
I'm kind of a noob with this stuff....but the start button is there right when the app opens. How would I go about programming that?
