NFC Tags

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!

Cool stuff, time to buy some NFC tags.

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!

[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....

Copying NFC tags?

Is there some way to copy one RFID NFC tag to another blank NFC tag with the SGS3?. I have 2 active NFC tags that I would like to mess around with and see if I can actually copy them and get the same access as my authentic ones offers.
So down to the question. Is it possible to copy the entire contents of an NFC chip and write it to another one with an app, and in that case which one?

bump* I'd like to know as well

copy a tag
"NFC Smart Q supports reading or copying a tag"
I just read this, didn't use this app.
There must be more nfc apps in Google's android shop, doing this trick.
I cannot post links, i'm sure you will find it.

Depends. If it's a tag without any protection, yes.
If it's a tag with crypto, such as most RFID door entry systems, contactless credit cards, subway cards - no, they're intentionally designed to prevent such things. (Specific systems may have been hacked, but in general, these are not copyable.)

"Not protected" means I can edit them as I want right??
So if I can solve the encryption manually than I can change my info on my NFC card with the help of my cellphone.
Is that right??

Agreed - may not work for everything, but definitely one of the better tag cloning apps.

Hello,
I am new at nfc so please do not judge me
I have one question:
It is possible to write dokumrent path in nfc tags for example:URL.
but on the path will be security level as:
login
pasword
And after you type your login and password it is automatically opened your dokument.
I was tried to write this way, but after I type login and password the link is not active longer and I have to search manually the document in my data base.
Waiiting fot you answers
For any information I would be thankfull.
P.S. It is possible to do this with my samsung galaxy s3?

This can't be this difficult...

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?

Write NFC tags that do not require other users to have the app used to write the tag.

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?
