Awesome. I'm gonna have to research this. Off topic but how much do those tags cost?
My mind is racing with ideas.... oh no

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.

Question for you guys with the nfc tags what have you done with them I like the idea of swiping my phone over a credit card scanner but what can be created with your own tags

Can't wait to try this. Already ordered the starter pack from tagstand. Looks like an amazing app. Will definitely buy as soon as I get my phone = ]. Thanks for the hard work.

@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).

Did you check http://www.tagage.net/tagage-shop/ ?

I purchased these nfc tags which the seller has confirmed that they are in working order and bought the application. However, the app says that the nfc type is not supported. What's up with that?

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.
If that makes sense?

[Q] allocate task to Locked NFC tag not programmed by You?

Hope this makes sense, here goes. As I understand the hole purpose of NFC Tags is that you tag them with information or an action or something like that. This is then written on the chip.
My question is: Can I use a commercial tag from let's say starbucks that's programmed to open the starbucks website do something completely different without reprogramming the chip? Simple words, a program that when it reads a specific tag, like open starbucks website, it does not open the website but activates bluetooth? Or is this not possible due to security/restrictions/no way of identifying a specific tag?
In the near future I can see commercial company's handing out free tag's that can then be used for other than intended use. Recycling NFC tag's(Is also good for the environment )

no. I don't think you can do that right now.....you have to re-program the NFC chip for any new actions that you want.
However; I could be wrong but I guess you might be able to use tasker so that if it reads a certain chip it'll perform a certain action....

There are currently no ways who are interesting for a non-developer. Start and do some research

youtube video of these codes coded into CM 10
these codes were originally in Nighty CM9 at around march 2012. it was then removed from the rom afterwards. these people at University of Texas has ported it onto CM10. these codes are pretty much the prerequisite of NFC proxy. which is a card emulation software, also work to proxy a card. and they have used it in the video to scan a card with phone NFC enabled phone, then the data collected is directly sent to the proxy. and allow it to simulate the card and purchase with the card.

Yes, but only in a state where it is almost only interesting for a developer's perspective. You can enable the emulation of a Mifare classic 4k card. And you can only write on it using a external writer and UID is fixed.

Noob. If we wanted this we would've read that thread.

That clearly isn't only interesting for a developer.
If what you're saying is true, and people are emulating Mifare 4Ks with a static UID on modern phones like the S3, then many people would be interested in using that to replace their door entry cards at work and school.

That is also true, but most mifare classic systems use authentication based on the UID wich is not to be changed externally. You can read/write under certain circumstances to the emulated Mifare classic 4k. But because it is a default applet, and we do not have access to the configuration of the card (Mifare4Mobile). I highly disregard using the feature because you might lose a correct dump of your mifare classic card.
But ofcourse, it is alot of fun. Sources are on the interwebs, http://stackoverflow.com/questions/12955919/enabling-cardemulation-on-android-ics-with-nfc-extras i have rewritten that code and it works.
Read again, when you are cracking a Mifare classic card and emulating it for gaining access to places where you do not belong without a proper card. you might get busted

That's not what I'm talking about. If, as you claim, you are able to emulate a card that has its own fixed UID, then that is highly useful. At my place of work, I'd be able to go to the IT guys and have them use my phone's emulated card's UID for my door access.
I'm not talking about shady stuff here.

Hi,
Thanks your help , but I still get same security exception.
Here is my step,
I am trying to use debug signature (debug.keystore) and modify system/etc/nfcee_access.xml like below
Code:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
<!-- Applications granted NFCEE access on user builds
See packages/apps/Nfc/etc/sample_nfcee_access.xml for full documentation.
-->
<!-- Google wallet release signature -->
<signer android:signature="3082...852e" />
<signer android:signature="3082...996ab">
<package android:name="com.rftag.cardemu" />
</signer>
<debug />
</resources>
After reboot my device and run test app again, the code throw exception at "nfcExtras = getMethod.invoke(null, adapter);".
And I don't see any message about NFCEE denied in logcat, Did I miss something ?
PS: for reference, My device is Nexus 7 and running 4.2.2 ( offical ROM, only rooted )

NFC full automation.

Hey guys. I have being scouring these threads for helpful information and nothing has really sparked an interest. Does anyone have any idea how to get full control over your phone through nfc to change systems stuff. Like location settings, connecting to specific bt devices, executing specific tasks.
Thanks in advance

You can do it with the right NFC Apps... BT Tag Writer to connect to specific BT Devices. Tasker is definitely the most powerful automation tool and you can trigger tasker task by NFC either with a plug in like URL Task Launcher or with some NFC apps like ReTag or NFC Task Launcher.
With those you should be able to do just about anything you want.

Specific nfc app

Hello everybody
I was wondering if there is a nfc app which makes it possible to write on a nfc tag to connect to a specific wifi-connection.

Yep, easy
Get NFC ReTag ...tap a tag ... name the tag....add activity "Add new SSID" (Wireless/Network) configure your SSID, Security and password and then use the Write option within the tag edit screen (action bar above) to write the activity on your tag.
Et voila, ssid and password written on your tag and everybody with nfc retag installed can easily connect to your network ....
Remark: Unfortunately, there is NO WAY to write a tag which doesn´t require an app to interpret the information, because Android (and the NFC specification!) doesn´t provide any native way to do this without an app installed... ... However, if someone without NFC ReTag installed, scans the tag, the tag will open Google Play and let the user download NFC ReTag (FREE version and less than 700kb).

Thanks! It works. I've been searching for an app like this one for so long

Hmm, you´re welcome .... and thanks for the wake up call ... either I should improve my marketing or you should improve your search skills ...:laugh:... NFC ReTag is currently the number 2 result within Google Play, if you search for "NFC"... ....but apparently a lot of people are not aware of it ....

NFC Retag was #4 when I just searched.
I particularly like that the app doesn't actually seem to write to the tag, it simply forms an association with its value that triggers my settings.
Samsung's TecTile app actually seems to change the tile's value. At least it seems this way when reading the tag first with NFC Retag, programming it with the TecTile app, and then reading it again with NFC Retag.

Yep, the Google Play search rank is currently a bit unstable ... Goggle obviously had just changed their ranking algorithm and mess it up somehow ....seems that a lot of apps jumping 100+ ranks up and down several times a day ...so #4 is a setback, but it could be worse
However, yes NFC ReTag doesn´t write anything on the tag, unless you want it to do so
It´s designed to work with read-only tags,too...therefore it saves all your activities in an app internal database on your device....
BUT it also has some cool write features: e.g.:
- the write Activity tag option mentioned in post 2 (action bar; tag edit screen) --> writes a cycle on a tag ... and usually needs a lot less space on the tag than the TecTile app --> means more activities per tag ... and it´s perfect for sharing your wifi credentials ...
- the write "special NFC ReTag tag" option (more button) writes only some small dispatching information on the tag ....so it combines both concepts (written tag + database) --> bulletproof dispatching, best performance, cycles and unlimited number of activities ... if you have writeable tags, I would always recommend to write a special NFC ReTag tag ....
So with ReTag, you can use both concepts depending on your use-case, tag size, requirement, restriction or preference ....Hack, you can even beam your tag activities from one device to another device
