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....

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.
Glad you like NFC ReTag ;-)

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.
Kind Regards

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.

Ok thanks for explaining what the neusens was. That have been fixed in the last update together with the workarounds that's linked in the app description.
Good luck with your future NFC endeavours

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
Ignore: Haha I accidentally posted in the wrong thread.
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??

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?
I am an IT consultant and would like to figure out a way to log systems as they are visited for maintenance with NFC tags. I figure what better way than to simply put NFC tags in\on the machines and simply tap phone or tablet to it to log it as serviced. So here are my questions
Is there any way to program the tags with specific ID's for each system?
Is there software that will track these things?
What apps would be best for this kind of use?
I would love to know about this as well .
I know that u can use a phone with a bluethooth serial code reader and manage inventory that way...but NFC is much better in my opinion

I'm no IT or inventory expert, but going along with your idea of QR codes, I did notice that the NXP TagWriter app has an option to convert QR codes into an NFC data set and store it on an NFC item. With that in mind, you could take your existing QR codes, scan and convert them into NFC tags. I'm not sure if scanning the tag would bring
I think another potential option is to store the barcode number as plain text, which can also be done within the NXP TagWriter app.
Note, you'll have to enable professional mode from the preferences before the QR and plain text options will appear.

i'm off the IT line for a long time already, php was the last thing i did. But some simple ideas pop-up. since its not out there, than built it sort of thing.
Is there any way to program the tags with specific ID's for each system?
yas, just use tagwriter and write tags with http address and an id at the end.
Is there software that will track these things?
local web server to catch input, ruby or php are simple enough. since you must have already registers an id for a tag for the job.
tags that have a web address and an id will be enough to do tracking. reports are printed from a computer anyway.
What apps would be best for this kind of use?
stock browser.
can do same thing with QR code.
I would like to get started with using NFC, but before I go out and buy a load of stuff I would like to ask a few questions. First off, do I need a NFC writer if I have my phone? Also, when looking for some stickers I noticed that some of them were already encoded. What does this mean for developing with them? Should I buy non-encoded ones (if possible)?
If there's anything else you think I should know before I get started with NFC, please let me know. Thanks a lot!
Usually I don't bumb but I really want to know more about this. Thanks!
1. There are loads of applications that can write on NFC tags. So yes, you can use your phone to write tags.
2. The tags can be marked or made read-only. Those that are made read-only cannot be changed at all. Usually tags that are already written (those that you can find on the back of posters) are made read-only. Tags that you buy online that not locked.
There are firms that can provide you with samples.
