[Q] Basics - NFC Hacking

I have a Samsung Galaxy SIII and just made my first NFC-steps using some Samsung TecTiles tabs.
After trying a few NFC apps from the Google play, I have a few basic questions.
While basic functions like p.ex. switching Bluetooth are available in all apps, other functions like p.ex. showing a pop-up, text-to-speech or calendar functions are only available in only in one particular app.
Is there a predefined set of nfc-functions for any given android version or the app-author is basically free to program any function he can think of?
I tried to import a tag in one app which i previously have written with another app. This didn't always succeed. I could understand that there is a problem with importing special functions which are unknow to an app, but at least the basic tag and the basic functions should be recognised by all nfc-apps.
As the nfc-apps progress, will we see new functions/possibilities or will it stay about at the present level as the available functions are limited by android?
My device is locked, mainly because it was mandatory by a VPN installation.
Is there a way to unlock it 'automatically' thru NFC? I know this can be a security issue, but it would be so handy just p.ex. to put the phone in the car-holder and it would automatically go to the home screen or the car screen, and also during driving its annoying when the device has a time lock and needs to be unlocked in the middle of an intersection......
What is the power consumption of the nfc-module in the S3?
Thanks for your input.

There is a set of predefined nfc-functions, (like open a webpage, vcard, open an app..) but this set is very very limited and even the mentioned Bluetooth function is not included .... in fact, bluetooth needs a little hacking, because the official api does not support to turn on bluetooth without asking the user .....so basically a developer can (/ has to!) implement every function he wants, but in reality a lot of functions are blocked on non-rooted devices, because android defined them as security related....

As mentioned the basic set is very limited.... it´s based on the nfc forum specifications and using nfc to control your device, is something these guys never had in mind ....so, sure you could use some standard nfc writer and write a webpage on a tag..... and this should be something every nfc device (not only android, but also blackberry, windows phone etc...) could handle .... but if you want to control your device, you need a more sophisticated app .... and there is no way to import a tag from one app to another ...
As the nfc-apps progress, will we see new functions/possibilities or will it stay about at the present level as the available functions are limited by android?

The functions are limited by android .... and my feeling is, that with every android update it get´s more limited! --> on Gingerbread, nfc was enabled while screen was off --> a function they skipped with ICS (ok, again, on a rooted device you could change the NFC.apk, to re-enable it) ... the last JB update declared the airplane modes as a security feature ... so no luck with airplane mode since 4.2 ...only to mention 2 examples ...don´t get me wrong, I don´t think it will stay at the present level, but it´s definitiv not in googles focus yet .... personally, I have a lot of new functions and use cases on my ToDo list, so I would say it´s just the beginning
My device is locked, mainly because it was mandatory by a VPN installation.

[Q] Windows phone 7 - Can you use it as a lock down device.

I'm trying to find out how to lock down a WM7 so that It Is only able to use its basic functions phone, camera, gps but blocks access to the to certain sites and the downloading of certain apps (i.e. games).
Would I be looking at a creating Custom Rom or is there another way to control what the phone can have access to.
Any Ideas or help would be appreciated.
K
at present there is no capability to perform this.
Well, who do you want to lock it down for?
You won't be able to download apps without a Live ID, so if your kids don't have it, they'll have pretty locked down devices.

I think it is not possible at the moment.
Desktop Windows has only had effective parental controls since Vista (2007). (There were relatively ineffective third party ones before.) Windows CE 6 (2006) only supports basic controls: http://msdn.microsoft.com/en-us/library/ee499001.aspx. And WP7 is built on CE6. Although WP7 is heavily controlled by its own mechanisms, so it could be added.
Management of controls was connected to Windows Live with Windows 7. This system could be added to phones, but it's all fairly new and there are other things to do first.
Thanks for the response guys
From what has been said it seems that this not really possible.
We are currently looking at what devices we need to acquire, and we need devices that can be locked down (Don't ask me why - management decision, probably related to data usage costs) so that user can only use it for work related tasks.
So OUT go things like gaming and social networking,
And IN are normal phone tasks's calling, texting, email, camera and the ability to sync to the cloud aslo, gps navigation.
We are looking at the WP7 phones because of Sharepoint as we have a lot of development planned that way and would like the ability to access that information remotely via a device.
Does anyone know of another way to achieve this or do I have to delve deeper Into the inner workings Wp7. Or failing that look at at different hardware/software.
Regards

MS should eventually update WP7 to be compatible with all the Exchange Activesync security policies which will give you the capability to achieve what you want. Additionally they have said they will add features so that enterprises will have the ability to lock down devices as they choose so if you are using Exchange already you may want to wait and see what MS produces. And you could always contact MS and see if they will let your company know what is coming down the road so you can decide whether to wait or not.

to lockdown marketplace (disable totally) you simply have to mod "LKG_Tuner_Config.xml"
and there would def be a reg mod to disable facebook
maybe this (I am looking for more
Code:

[APP] BT Tag Writer

BT Tag Writer is application that offers you way to add NFC pairing to your old Bluetooth speakers. NFC pairing allows you to pair, connect and disconnect the device just by tapping the NFC tag with your phone. This application is still under development and this thread can be used to request changes and new features for this application.
Market: https://market.android.com/details?id=fi.siika.bttagwriter

--- original first post ---
Hello everybody.
I have been now writing application for Android devices with NFC capabilities. It basically offers wizard interface for writing new NFC connectivity tags for your Bluetooth speaker(s)/headset(s)/etc. And software that will take care of the actual pairing/connecting, when you tap the tag with your phone. NFC pairing is something Nokia does with N9 and it's Bluetooth speakers, but it looks like Android still doesn't handle this well out-of-the-box. Also I still haven't found easy to use connectivity tag writers for any devices.
Sort demo of application in it's current state: Check youtube video kzoG5VM6VcU (can't have this as a proper link, as I only have less than 8 posts to this forum, sorry)
Before I release this software to market, I would like have some people testing it with their speakers and devices. I really hate alpha level software in market. If you have Galaxy Nexus, some sort of Bluetooth speaker(s)/headset(s) and hopefully some writable NFC tags, and you would like to help me to get this software tested: Please tell it here. I still have some small things to resolve before this is ready for closed testing. If you like to help me to get this tested please also tell what sort of Bluetooth device you have and what NFC tags you have available.
I will most likely release this software as free (gratis) and probably in open source (don't know the license yet). So I am not planning stealing your time and then making money out of it. Only thing I can offer to you is to add your name to application's thanks list.
Also if you know software that already does all this, please tell. If my software does not bring anything new, I have to redesign it little bit.
Thanks.
I'd like to test your app.
Got the same NFC-Chip like you (mi(d)fire or something like that I've bought for my old Nexus S) and a Nokia BH-504 Bluetooth Headset and for sure a Galaxy Nexus and a Galaxy S, too
Just tell me how I can help testing...
i would test as well buddy!

For now this is ICS software, do you happen to have some unofficial 4.0 image in those? I kinda would like to make this 4.0 only software, as all NFC devices most likely will get that update.

I'd love to test this. I've been using NFC Task Launcher to do something similar but it doesn't currently support connecting to a specific device. I'm running ICS on a GSM Galaxy Nexus and have several A2DP speakers I could test with.

I will fix few annoying things and then will put link to debug apk-file here (maybe Wednesday). I will try to see if I can make it run in 2.3.5+ too. Anyhow software will be limited to Mifare Ultralight tags (original and C versions). I have to buy other type tags to see what I can do with those, but that's later. Common Ndef writer classes does not work at all with Android or then I'm doing something wrong.
Android also really limits clean ways to do intents for more complex tags. So these tags software now writes are not proper connectivity handover tags. Just the core part of those is used and stored as single NDEF mime item and then this app is marked to handle those NDEF messages/records. Positive side with that is of course that information fits to smaller tags. Also PIN code storing will be probably done little hacky way to the first version.

So many different Mifare tags out there. Mifare Classics will not work (for now).
Anyway, pushed software to market after all. In few hours you should be able to find it from there. Offer still stays, if you can try it out and report issues here it would help. I had to drop headset support for now as it didn't work as well as I hoped.
Great! Will try it out today. Here's the market link https://market.android.com/details?id=fi.siika.bttagwriter

Missed that bit. I really must learn to read All the Mifare tags I have are Classic ones.
A couple of initial thoughts after myfirst use of the app...
1) Back when I was on 2.3.7 there was a Bluetooth A2DP widget I used (can't remember the exact name now) that, when you created the widget, would display a list of already paired devices that supported the A2DP profile. Once you'd picked one the widget would attempt to connect to it automatically.
I'd like to see your app do something similar rather than having to go through a pairing process with a device I've already paired with. It's a small thing to do I know, but I'd imagine most users will have already paired with their speakers before ever finding your app. I don't know if you can enumerate paired devices supporting the A2DP profile in ICS though.
2) When your app was scanning for BT devices it would find my speakers but would only display the BT address. It didn't display the BT device name after waiting for several seconds. This may be a BT stack problem though.
3) It looks very nice!

1. Yes my app does not trust the already known devices list. Have to see if I can get that too. Anyway my application does not pair devices that have been paired already. It simply is stupid to not offer those. I have to check if I can used paired devices list too. I have to add some indicator to list what devices are then old known and what are just found with discovery.
2. I have seen "no name" issue only once. But yes, that's "stack problem"... I hope
Anyway I think I have to try to add Mifare Classic support first.

Sorry for spam, but finally this will be mine 8th post
Request to list already paired devices is now added to Market version (0.3). So no need to turn already paired devices to pairing mode when writing tags.
Support for other than ultralight Mifare tags might take some time. Thanks to keys etc those tags are not ideal for this use. I think I will try to add headset support first.
Just to confirm that 0.3 is listing my paired A2DP devices

My unofficial NFC tag type list (from memory, might have mistakes)
Mifare Ultralight C is my recommendation. If you plan to use this for this, or for example: storing your contact information, storing some url, storing application starter information etc.... Simple, cheap and easy to use alternative.
Mifare Ultralight (non C) is too small for almost anything. You can use it anyhow with my software (limited features) and you can fit sort URL to it.
Mifare 1K, Classic, etc... these are for more secure needs. Or if you really want to store a lot more information to the tag. For non secure usage (e.g. my app) the secure features are just annoying extra that makes things more complex. Key based security so if you mess up with key, then you can't read or replace that data anymore. Also kinda "proprietary alternative".
Felicas are Sony's alternative for all these. Probably not easy to find outside Japan. Topaz is good alternative for Ultralights, but I don't know how well Android supports those currently (haven't tested). And if Broascom/Innovision still makes these? Not too easy to find anyway. And then there are many more... it's a total mess and maybe the main reason why it's so hard for NFC to break big time.
But for the most of use cases: I assume Mifare Ultralight C is the best alternative.
NFC Tag store examples:
TagAge - I'm using this, but mainly because I live in Finland.
NFCDog - is one UK alternative.
And many more, Google search is your friend. And this message has't been paid by either of these stores

Tasker/Locale NFC Plugin

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.

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.

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.

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?

Is there a way to replace TrueCaller?

I tried a number of things to get the Google dialer without success.
For now work with kk dialer, has anyone any idea how to get rid the TrueCaller?
Just don't use TrueCaller?

I gave you the advice you wanted about Truecaller. As the previous poster stated, you can disable it, or, as I advised, simply not use it. Getting offended because someone took the time out to respond is terrible manners.
You may need to be rooted to remove it and we do not know if you are rooted. We don't know if you are running a Lollipop or Marshamallow ROM either. You have not helped us to help you by not giving us your platform information.
Have you tried to install the Google Dialer from the modular GApps thread?
Be warned that they are targeted to 32bit ROMs. Do a backup!
You could also try CM Next dialer from CM C-Apps package. This also includes Truecaller, but it is trivial to disable it.
I am rooted and am on stock TOS208G with trucaller uninstalled. I replaced with caller ID & call recorder app https://play.google.com/store/apps/details?id=com.callapp.contacts that I prefer.
I have found the phone does not display whose calling via contacts only by the true caller ap. Have I installed something in error or got a setting wrong please?
Trucaller help in many ways

From what I have found, there is no caller id system on the phone without having one of the various true caller id apps installed.

Caller ID is a stock feature of any basic dialer out there (Google/AOSP etc), it should not be dependent on True Caller.
I think True Caller is still on my Swift, so I will test this later.

Uninstall true caller id and see for yourself then, you don't have to trust the contents of members post if you so choose.

I don't have TrueCaller on my device afterall. The dialer is the stock Android dialer and my caller ID works without issues.
What's the packagename for TrueCaller?
Sent from my P00A using XDA Labs
I wonder if I can restart this discussion here -- I want to turn off TrueCaller, but in Google Play it says it's a System App and it does not appear at all under any name in the Settings - Apps listing (no matter whether showing or hiding system apps). What other options do I have?
I'm on Android 7.1.2. My TrueCaller has no options to either turn it off or to turn off the notifications it brings up (which is my main reason for wanting to get rid of it: for something that's blocking spam, it spams me far too much with stuff that I don't want it to do).

This should indeed be the case. Unfortunately, for us Swift (1st gen) users at least, this is now broken.
When Wileyfox migrated from CyanogenMod to Android they broke a few things along the way as well as doing a deal with the Devil aka Truecaller.
Unless your device is Truecaller enabled then caller ID simply will not work. We've tested at least two dozen dialers and contact managers (all from Google Play) and not one of them works with the Swift in its current firmware state. We even installed the APK of the Google Phone dialer (provided by WF themselves and which according to Google Play is incompatible anyway) and even this does not work.
Besides, how many dialers does a mobile ecosystem need anyway? One has to ask themselves why there are so many and why they nearly always require OTA registration to do what they offer....
But that's another matter altogether.
There are other issues too such as SMS alerts going off at full volume in the earpiece during an active voicecall; or the persistence of 'charge mode' when connecting via USB, even though MTP has been set in the developer options or from the status pull-down.
One thing it tells us is that the Swift cannot be running stock Android - otherwise these problems just would not happen. If not that, then it is that WF don't have a proper working build process or test protocol.
Either way, the Swift is damaged goods now and it might seem WF are prepared to kick it into the kerb. Probably the best option now is to try Lineage, assuming owners are savvy and even want to.
On the other hand we could band together to oblige WF to get an update released. We have been trying for months to get their attention, both before and since their buyout by STK. For those who are minded to, perhaps you would like to add your support by liking the following Facebook post:-
https://www.facebook.com/officialwileyfox/posts/1872330073078309
If enough give it the thumbs up then WF may be moved to respond. Please support this initiative if you can.
Thanks.

We think we have found a solution:-
It ought to be possible to disable Truecaller but not remove it entirely unless your phone is rooted and have other management tools. We have managed this is on our own device which is totally stock and never been tinkered with (7.1.2 Nougat, Build No: TOS257G – N2G48B).
Secondly, installing another dialler from Google Play or via APK will work but it's almost 100% likely that a further setting will need to be made: setting as the default phone app.
This can be done in two ways:-
i) Settings->Apps->Configure Apps (Gear icon in top bar).
ii) From the app drawer, drag the dialler app icon to the "App Info" drop zone at the top of the screen. Scroll down to the setting that says "Phone App" - it should be yes or no.
See attached screenshots for reference.
It seems to us that many owners think their Swift can't be used with any dialler other than Truecaller, when in fact they can; the mistake is on the part of the firmware which won't recognise another dialler by default and hence breaks the contact ID display when incoming calls are received (not to be confused with caller ID).
Hopefully this serves as a solution. :good:
