So I have some tags, and what I want to do, is make a NFC Facebook check in for my bar. So when someone comes in, they can scan the NFC and it checks them in. Easy? lol
I can easily make the tag with NFC task launcher, however when I test it with a phone that does not have NFC task launcher, it doesn't work. But, it works fine with mine.
How can I write a tag that will allow users to scan a tag and check in?
I have tried several NFC writing apps, and none seem to be able to write a tag that can do this.

that my dear friend will be the magic sauce. a lot of things are possible when you have custom programming but its just that custom.
I am pretty sure what needs to happen is FACEBOOK ITSELF needs to support this. IE they need to have facebook on the phone and that app needs to support "checking in" via NFC.
then you can make a universal tag that anyone can "tap" as long as they have the facebook app.
no matter what SOME custom program will need to be installed unless its built into the OS
i think i got it to work
what i did was take the URL from our facebook page and wrote that to the nfc tag.
my issue with that was the URL was https://www.facebook.com/stuff/mores_stuff
once i changed it to http:// it started working
also doing it that way works great because the page it brings you to not only allows you to check in, but you can also like the page, tag your friends, etc.
now i just need to have more people with different devices test it out.
then i'm going to make NFC drink specials and menus
That is an awesome idea! This is the kind of ingenuity that will hopefully prompt more manufacturers to implement nfc in their devices and more companies to use nfc in their establishments.

Cool idea and thanks for sharing the solution - good info to have when people ask!
Sweet, glad I found this. Though I still had problems through NFC Task Launcher, I completed using NFC Writer.
At the business I am creating these tags for, I do have some questions. (Hope this thread isnt too old to dig up)
I'd like to also write 4sq, google, twitter check ins. I saw this capable with NFC Task Launcher, but again anyone whom taps the tag without the app will be directed to the store. Or would it be better to write a tag for each?

So was anyone able to scan any NFC tags?
some stores has NFC payments enabled, some movie posters or stuff like that has NFC chip build in
in some countries there's NFC tickets for the bus/subway
so, it all really depends how popular or not it's in the are where you live
not even all USA cities are that high tech
I've heard that NYC taxis and some pharmacies and such there support NFC. But I've also heard that the phone's software isn't really setup to use the NFC yet. I know that Sprint and the Google Nexus S 4G have Google Wallet hooked up to their NFC.
I don't know that TMO has a deal with Google Wallet. Are they part of that Isis group?
I've successfully scanned my SFO Clipper card which uses NFC. Pretty cool.
The venture is now developing provisioning systems that will allow existing payments services to be added to any NFC phone owned by a subscriber to any of the Isis founder's mobile networks, says Johnson — and Isis already has a number of banks ready and willing to pay for this service. "When we launch next year we will launch with multiple banks," he explained.

I've been testing krohnjw's NFC Task Launcher app. I must say it's pretty damn awesome! It lets you set tags up for doing different tasks. I'll make a video sometime, he has some on his development page. You can set a tag to enable wifi, for example. One idea I had was to use his app to set your phone to toggle bluetooth when you place the phone in your car dock for example. Very neat stuff!

I'm still looking for the best price on cheap tags to mess around with. I've also read there is some confusion around the net as to which tags will work with our phones/phones in general.
NFC Tags, what works, what does not
I've got two TMO SGS2s, so I did some NFC testing the other night. Here is what I found:
1) Creating a text tag works. Reading it from another phone works. But when read, it put the text into a new post in the Google+ app. Not really what I imagined wanting to do with an NFC tag that I read.
2) Sharing Google maps locations over NFC seems to work. But again when reading the tag, the text and URL is opened up as text in a new Google+ posting.
3) Web page URLs. I used Dolphin HD to share a few web pages. Reading the tag properly brought up the website. This one feature seems to be more or less fully operational.
4) Sharing contacts over NFC did not appear to work at all. It is an option when creating a new tag in the Tags app, but we couldn't get it to work for any type of contact.
Are you able to read arbitrary RFID tags using the T-Mobile Galaxy S 2? I've tried on several different types of RFID tags with no success (NFC was indeed enabled when I tried):
-Passport
-Building entry badge
-DC Metro SmarTrip card
I've tried using the included "Tags" application, in addition to "NFC Reader" and "NFC TagInfo".
Oddly enough, I stopped by my local T-Mobile store, and the representative told me that he was unable to transfer URLs or random tags (or contact information, as you stated) between two Galaxy S 2 devices, or between a T-Mobile Galaxy S 2 and an HTC Amaze. (We then played around with the devices a bit in an attempt to get something working, but to no avail.)

I haven't tried reading any physical tags. Only between 2 different NFC enabled phones.
I did a whole bunch of research with the Nexus S NFC reader - and so far as I can tell, the SGSIIX has the same capabilities.
I have a bunch of blank 1K, 4K and Ultralite MiFARE tags that are AWESOME to play with. Even just putting your contact card on there, or URLs (you can do anything with a URL) is tons of fun to play with. They don't read proprietary NFC implementations without special software - only tags encoded with an NDEF structure will be automagically picked up by Android.
The good stuff is coming up - I'm 98% sure that Zoompass is coming out with an Android app compatible with the QuickPay/Interact-Flash readers. Next year, pay for small crap with your phone!

They are pretty reasonable. If you check out the site I compiled a list of shops that I've tested. Usually $1.15 - 1.50 a piece for Ultralight C or Classic 1K tags.

@krohnjw
Can these tags be pre-defined and written into the software?
Was just thinking, you could be onto a winner here.
Set your program to know whats tags are, so say put a tag for a store. When someone scans it with your app, it auto checks them in at whatever app they have installed

The instruction set is encoded on the tag. Any user with the app that scans the tag will see the same actions performed. It makes no calls back to any server or outside service.

It's fairly simple. I designed a basic syntax describing the actions to be taken and wrote a complementary parser for when the tags are read.
That's simply amazing. I knew the NFC would be a nice toy, but not that nice!
Does anyone know where to get some cheap tags in germany. Cheapest I found so far was ebay, but still around 2,50 EUR per tag (incl. shipping).

See the edited first post. Something in 4.0 changed and Mifare Ultralight, Ultralight C and Classic 1K tags are no longer reporting as NdefFormatable - so the functionality to format them TO NDEF is broken.
Essentially the NdefFormatable class verifies that the tag lists the tech before it will operate on them. As they no longer list that tech it refuses to do anything with them.
This affects all NFC Apps I've tried in the Market so far. If the tags are already formatted NDEF then they work without issue.
I've got a bug report open to see if I can get a response on this as well as a post on the dev group as it's not a listed change in the API changes anywhere from 3.0 up.
If you don't want to wait it out and want a refund let me know and I'll process it.
Its allright, seems like a decent app so I still want to explore the possibilities.

There are shops that sell the tags pre formatted with NDEF - those will work. Anything that comes blank though currently will not.
As a curiosity I sent an email to NXP as well to see if they have any more information. I'd like to get this sorted sooner rather than later so hang in there
Can this app be set to do something when moved away from an NFC tag?
So say you put it in car dock and a tag turns on BT. But when removed its turns off BT

No, there's no intent raised when the tag is moved out of range, only when it is detected.
It is reported in the logcat, but to do that you'd need to constantly be reading the logs and scanning for that (which would involve a read logs permission).
For all Europeans: I contacted tagage and their tags are not pre-formatted by default, but if you send them an email, they'll format your tags first.

Most vendors don't pre-format their tags - so get in touch with them before/when your order for now to be sure.
Hopefully this is something that I can get an answer on, but I don't currently see a good workaround.

Can you put implement it as an option on each tag? That way we could enable it for a car tag only and not another tag etc.

I just purchased this plugin to use with Tasker:
https://play.google.com/store/apps/....&purchaseButton=9yzEcX63VIYisA_oRMh13HqYUXs=
Seems to work ok, but ever time it scans my NFC tag it pops up a dialogue asking if I want to "Activate NFC condition" or "New tag collected". I just want it to kick off the action in Tasker without any dialogue. Anyone have experience with this plugin, or should I use something else?
Nevermind... got it working with NFC ReTAG FREE. Works great! Don't mess with the app I posted a link to above, it's a pain to use.

Hi kimboinatl!
I'm the developer of the NFC plugin for Locale. The reason why this chooser pops-up is because there are multiple apps on your phone that can handle the NFC-tag that was scanned.
This can be solved by either disabling the other apps that the NFC scan action can choose from or you can create a unique tag following this guide.
I'm glad that you have been able to solve your needs with NFC ReTAG.
May I ask what it is that makes it a pain to use ? The feedback is greatly appreciated so that I might make it more pain free for other users.

Hey m3llon,
I think the the problem was getting rid of the popup. Typically when there are multiple apps that can be launched from an action my phone gives me the option to select a default, but I couldn't do it in this case. I spent a while trying to figure out how to disable the popup, or if there was another app that was causing this, and had no luck, so I ended up uninstalling it. If there was a way to specify what the default action was I probably would have kept the plugin. Sorry if my feedback sounded a bit harsh, I was just grumpy after not being able to get it to work the way I wanted it to. Thanks for checking in with me about it, I appreciate the work you have put into it.

Just in case anyone else has issues with the popup, I find that using non-formatted tags doesn't produce a popup. Once the tag is formatted, or if you buy them preformatted, it doesn't look like it can be UNformatted though (wiped, yes.. but not unformatted)
When I first got my GS3 and started scanning everything possible, I found that some tags would produce the popup discussed (despite having no other nfc apps installed), and others wouldn't.. I ended up realising that unformatted tags don't produce the popup.
I ended up using the Tasker/Locale NFC Plugin as I didn't want something else running all the time when I had Tasker for that - and since the plugin uses the serial number (or what I assume is a serial number - it's different on each tag) rather than what's written on the tag itself, there's no need to format it - Same would apply with NFC ReTAG.
So as long as any tags are unformatted, you should be good to go.
So I bought the plugin and wrote the bad://access/developer URL to one of my tags. I scan it and Locale reacts accordingly.
But then what? Locale is in that situation forever.

Yes, you will have to scan another tag to exit the situation.
For using Tasker with NFC Tags I like Tasker URL Launcher the best. Once installed you simply write a short URL that ends with the name of your Tasker Task to a tag then anytime you tap that tag it intiates that Tasker Task.
I did at one time have issues with those pop-ups (new tag collected) and through much searching found that I needed to disable a system app on my Galaxy S3 called "Tags". It wasn't there on ICS, but was after the update to Jelly Bean so not sure if it's something Android added into JB and not sure why they would or what it's purpose is, but disabling it fixed the annoying pop-up issue and has had no affect on reading/writing tags with various apps.

They can be unformatted. Using NFC TagWriter by NXP (which I LOVE), you choose Tools > Clean. This resets the tag to factory default (unformatted). NXP manufactures the Xperia tags, they make nice products.

Thanks for that.. That definitely wasn't the case when I wrote the post as I'd tried with numerous apps (including NFC Tagwriter, which is also my go to app for writing) and using the Clear option left the tag wiped, but did not leave it in the same state as prior to formatting.
Also, the developer of the app implemented a direct url that could be written to the tags so that only this app is launched - so the need for unformatted tags (when using this app at least) is somewhat moot.
I have this app and I must say it makes building tasks extremely tedious.
If you want to scan the same tag twice, you have to put an action in your task to disable the first task after the first one is done and then put a disable of the task you are running in the second task.
Also, both need to run as exit tasks.
It would have helped if the dev used some better logic and came up with exit tasks on repetitive scan

You can also use the app StartNFC Expert to "unformat" a tag. It's a great simple app for formatting/unformatting and testing tags and seeing what types they are etc.
It's extremely disappointing they the developer has completely abandoned this plugin.
Solution
Hello !
A solution I found to avoid this popup :
- Scan a tag (popup appears)
- Long press on the unwanted app
- Choose disable
- Enjoy the plugin
You can also go to your apps list and search "tags" and disable it
Hopefully pent does something with NFC in the next version of Tasker so we can be rid of this unsupported plugin.

Hoping someone is still using this plugin and can answer my question...
Do I have to have two tags if I want an on / off tasks? For example, I have hue lights and I would like to turn off the bedroom light on / off with the same NFC tag but not sure if that is possible
No.. Just use the check box for repetitive scan

Hi
I want a good nfc task App. I have seen one called nfc tasker. But is it any good? Dødes anyone have sugestions for other apps?
nfc task launcher, they have cheap tags through their app store too
Is it easy to use?
+1 for NFC Task Launcher. Best & Pretties NFC app.
Real easy to use. Pick a Profile (Car, Home, Bed, Office), and write to tag. Add other task to the pre-made profiles, or make your own from scratch. Erase tags too.
If you want to write URLs, V-Cards, Messages, etc then get Tagstand Writer (by the same developers of NFC Task Launcher)
(also in NFC Task Launcher, scroll to the left to "Free Tags" and get two free tags by posting to Twitter)

Basically NFC is based on RFID standards but uses different frequencies so the two don't work together. That said, many companies are embracing NFC now and things like Mastercard Paypass and Visa Paywave technology use it. If these companies pulled their finger out and actually started allowing us to connect our accounts to the phone through the likes of Google Wallet, we could do away with physical wallets altogether!
Security is the big issue though and this is why you will never be able to just scan and then use a card, imagine how easy it would be to just swish your phone past someones wallet in a queue and then pay with their card! There is already equipment fairly readily available that can be put together and programmed to do this, putting that tech in everyones hands would be asking for trouble.
Back on topic. I highly recommend NFC Task Launcher and, for ultimate automation, use it with Tasker. That lets you do basically anything you want with your phone at the simple swipe of a tag.
I see, I did get a all that reads the access card @work so I was thinking that an app would let me read and replicate so that I could enter the office complex even if I forgot my card...
I have a done a bit of looking but all I've come up with is mainly 'use trigger' or something like it. But my question is: Is there a way with Trigger to write a tag that anyone can read? Or is there another NFC tag writer app that I should use?
The thing I want to do is make a tag for friends to tap when they call over that will connect them to my wifi network, but if they have to go and download trigger first then no one is going to use my tag.
Sorry if this is a re-posted question, I looked and didn't see it anywhere here and when I put the title in there was no recommended threads that had what I was asking.
I've tried different apps, and it looks like connect to wireless is not one of the default actions that is included in Android. I've only found connect to bluetooth.
Hi, you can use NFC Tools for that.
All records on "write" tab is compatible with other NFC device.

I am new to NFC and I am a little confused about what NFC can do. I have the nfc-tool App and I can read many NFC tags that I have.
But for an Android phone with NFC support, without installing any 3rd party App, what can it do? Is NFC enabled by default? Are there native NFC apps that can trigger action, open URL, etc?
Also, since each NFC tag already has a unique identifier, it seems to me writing data to NFC tag isn't all that useful when only 1 phone is using it. As you could have just programmed the command to the phone. The same applies to multiple phones if you can program the phones through some other means. Am I missing something here?
As I was saying, looks like what you want is only possible in Android L.
Have a nice day!

Android has native build-in support for some simple standard NFC activities, like reading a messages/contact, open URL/URI, launch application etc. .For more sophisticated activities you will always need an app to parse the tag content and handle the activities.

I'm a newbie here. I have a phone running 4.2.2. How do I make it read an NFC tag and take action without installing additional app? Just tap?
So I finally found an official NFC tag in mall. When I place my phone on it, it asks me to choose between stock Browser and Chrome. I guess if I have already chosen a default, it will just open a webpage. Now I wonder if there are security concerns. What if the URL is malicious? What if it downloaded a lot of data when the user is roaming?
I wonder what other functions an NFC tag can trigger without installing additional Apps? If I buy writable NFC tags, like the Samsung TecTiles, can it be programmed just like the mall NFC tag?
