Well.... I want to make one specific page (in this case 3) read-only.
There's any app that does this?
There's a few apps like NFC TagWriter by NXP and NFC Developer that can write-protect tags, but I think it only works on the entire tag. You might have to use a tool on a PC and a usb dongle.
What kind of tag do you have? Most of the mifare tags only allow you to write-protect from any page to the last page. So if you wanted to protect page 3, it also write-protects all the pages that come after 3.

Hi,
I'm looking for a way to read & write on a Mifare Ultralight. I know a couple of applications available on the Play Store allow the possibility to read them, but I didn't find any application allowing me to write back (for example, change the data and save it back).
Is there a way to do so?
Also, is it possible to plug in the Android to my computer to use the NFC capabilities and to code in another language than Java? (some kind of bridge)
Thanks a lot for your support!

Have you tried NXP NFC Writer app? As of now there is no way to use your phone as a USB NFC reader.
Well I have both TagWriter and TagInfo. I can read the content of my NFC chip with TagInfo, but I can't with TagWriter. That's why I'm looking for something else to do the job, but can't find much on the Play Store.

Is the tag write locked? Formatting Classic 1K tags to NDEF is part of the standard NFC/NDEF libraries on Android. This allows full write access.
If you're trying to do it without NDEF then you have a different set of issues you'll need to deal with.

Well, some pages are writable, some others aren't. Still, I can't get it to work with any apps I found (also the one people suggested in here).
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?
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 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?
Please take a moment to read through this before posting, not only is a brief description of NFC and some of its uses included but also you will find a few of the more commonly asked questions. Over time these will be added to accommodate new or recurring queries that are being seen in this thread. If you have come to the thread to ask about emulating, copying or bypassing your Mifare card head down to the FAQs below .
What Is NFC
Near Field Communication (NFC) is a technology that was built upon Radio Frequency Identification (RFID). It allows for the storage of data without the need for a direct power supply. When a reader such as a NFC enabled phone comes within range (usually an inch or less) data can be read/written from/to the tag.
Objects containing NFC can be found in two varieties, active or passive. Passive devices are ones that contains data but do not read and generally will not have their own power supply. These are found in NFC tags such as those in Credit/Debit cards, Student or ID cards, Library books and passports among many. For a much larger of scannable objects see here. Their are also active devices, these can read information stored on other NFC devices and for the majority of us here these will be our phones. These active devices can also usually alter the data found on tags or transmit/exchange data with other active devices.
Uses for NFC
NFC has many uses both commercial and on a development/hobby level, here are just a few:
Contactless payment
Transfer of data from phone to phone
Share and log on to WI-FI
Sharing contact information
Automating tasks
Storing bitcoin wallets
Disabling alarms
Send Wake-On-Lan commands
FAQs
How can I emulate, copy, edit or bypass my Mifare card (student ID, work ID, Bus pass etc)?
The short answer: you can't
The long answer: There are numerous reasons why you may have had issues finding this information on XDA. Primarily because it is not possible from the vast majority of phones and for good reason. Mifare as mentioned above is a security layer for NFC cards and therefore the process isn't as simple as just downloading an app, scanning a security card and then forgetting about it. Secondly depending on the type of tag you are trying to use this is either A) illegal or B) against your companies, service provider, school's security policy and as such you will not find this information on XDA.
Your options from here are: look elsewhere for this information, just use your card as instructed or speak to your IT department about adding another form of NFC tag to the system, I for instance have an NFC tag implanted in my hand which my IT department was more than happy to add to my user profile at university. More information on this can be found here.

How can I make Android trigger an event when I scan an NFC tag?
For simple commands you can use apps such as NFC Tools or Trigger.
For more complicated tasks a combination of Tasker and Locale can be used to launch just about any chain of events upon finding a specific tag. Of course alternatives do exist, so be sure to check out a few of the other projects around the site
