[Q] NFC detects my work ID/vending card - Nexus S Q&A, Help & Troubleshooting

Hi
This is my first post on the forum but have used the forum for a while and its a great place.
By chance I put my work ID/Vending machine card (one that you top up with cash to use the vending machines) next to my Nexus S and it flashed up on the screen 'new tag collected' and 'unknown tag type'
Whats does this mean? and interestingly what can I do with it?
Has anyone else had this?
Cheers for looking

I just did it as well.. same thing.. I think I'm going to try to use it to get past security and buy lunch Monday
Edit: never mind it won't let me 'share' the unknown tag
Edit2: there are apps that will let you store it and share it in market.. So trying this monday..

nfc is what most touch badges use ironically. You would have to have the nfc transmit or resonate the same signal as your badge for it to work

Even I am interested in this ... Any luck with swiping your phone to get past the door?
Also, if it did work, could you tell me what application you used to share the unknown tag? I am, right now, still waiting for the 2.3.3 OTA (yes, i am a bit of a noob)... but i guess if this thing works, i wouldnt mind being a bit adventurous and installing OTA via my SD card (yeah ... you're right..if i take that to be 'being adventurous' u know how big a noob i am )

Didn't work.. at least it didn't work with the vending machines. I didn't try the security gate.
I tried a couple different nfc apps from the market. There isn't very many, could toy with all of them.

aww maan...wud've been totally awesome if it'd worked though ..
i have to use an access card to get thru everything here.. entrances/carparks/doors/ office rooms ...
oww well..guess i still have to stay old school
thanks for the confirm though..

Just to shed some light here. It is possible for the Nexus S to push a message to a waiting device. However, it currently pushes NDEF messages.
Most of your "security" based RFID tags are probably not NDEF formated. Many use the MiFare Classic tags due to size and their low cost. These tags can be formated to NDEF for use with the Nexus S (that's how I use them), but likely aren't that way out of the gate.
Run a logcat when you touch the tag look at what the intent coming in says.
For an NDEF formated tag it will look something like this:
I/ActivityManager( 118): Starting: Intent { act=android.nfc.action.NDEF_DISCOVERED typ=text/plain flg=0x10000000 (has extras) } from pid 200
I/ActivityManager( 118): Starting: Intent { flg=0x10000000 cmp=com.android.nfc/.TechListChooserActivity (has extras) } from pid 200
Try NXP Tag Writer and see if it will read the card contents or identify the type of message stored.

present NFC application & uses

I have been following Skyrocket development from day one, and yet I am confused about the push for NFC in current ROMs.
How is everyone using NFC with their Skyrocket at the present time? Certainly I understand the potential future uses for NFC -retail, data, ect; but what functionality does it serve anyone now?
A quick example. I have a nfc tag sitting on my nightstand. At night when I go to bed I set my phone on the tag. It automatically turns my wifi off, turns my alarm on, and turns the night mode clock on. Its really neat stuff. Paying with NFC (which we can't do yet) is only scratching the surface when it comes to this technology. If your interested more Google search it. There is tons of stuff.

that's something I haven't thought of! cool example. Where do you get the tags? I assume you might then use a program similar to tasker with NFC support?
Funny story. Its actually a rewards tag for a gas station I frequently visit. You just scan the tag at checkout, I'm sure you've seen something like it before. I was just thinking about it one day and came to the conclusion that the tag had to be NFC. So I stuck it to my phone but the pre installed NFC app just kept force closing, so I downloaded one from the market and it worked. I can read and write to it no problem. however my wife has a similiar tag for a different store and I can read it but I cannot write to it as for blank tags just Google search "blank NFC tags".

I'll chime in as well I'm on Alien rom and I got my nfc tags from http://tagsfordroid.com/tags/Home.html. NFC Task Launcher is a cool fairly cheap app that lets you do quite a number of tasks from a nfc tag. If you want to write just standard nfc tags then I like NFC TagWriter by NXP.

I keep meaning to build an NFC into my house lock so I can just scan my phone to open the door, never get around to it though.
Android beam is pretty cool too. If I'm looking at a webpage I just put the back of my phone and my wife's phone together wait for the prompt and touch the screen. It opens up either web page, you tube, whatever and then opens up what I was looking at

Just started using nfc on superlite 5.1, ordered 5 blanks from ebay for around 5$ i presume, you could probably get it cheaper from the US sellers.
I'm using NFC task launcher which works great and you can combine it with Tasker.
At the moment I have a tag attached to my car dock which automatically reduces brightness to 0(so my battery wont overheat while charging) and opens the GPS.
Only got my tags yesterday and downloaded the apps so I still got a lot to learn but so far it seems really useful.
I imagine to people with an office or those who use the phone for work stuff it can be even more useful for forcing a sync or almost anything you can think of at a certain place.
Great info in this thread - I now have a tag that will toggle silent and full volume on my phone (for when I go to bed at night and wake up in the AM), using NFC Task Launcher and Tasker.
I am trying to eliminate the audio notification when my phone reads a tag, but have not found how to do this.
Anyone know if it can be done?
This sounds really cool. I have been searching to find free tags offered by vendors, but haven't had any luck. Does anyone know of a place like the gas station mentioned earlier that gives NFC tags out? yes, yes....I sound really cheap. I am.

At the moment there doesn't seems to be way to do it in the app itself, you'll have to contact the developer. But when I used the phone on a tag when silent mode is on there was no noise, so maybe you can use tasker to silence it right before and enable sound right after.
To the other guy just buy them, I bought 5 from ebay for 5$ and at the moment got no use for 4 of them.

So, does NFC work?

I tried reading the NFC chip on my US passport card, but the phone doesn't pick anything up. I've tried two different apps from the Play store and I turned NFC on in the settings, but it doesn't do anything. Has anybody got it working? Have any tips?
Thanks!

I tried Android beam by touch my One X with my GS2 and both reacted with vibration and sound. So, yes, NFC works.

I'm assuming NFC based data communication isn't universal. That'd be pretty messed up if someone could walk around with a phone and run into people in a heavy tourist area and have access to their personal information.
Android Beam has to be enabled to both devices (or the equivalent on whichever other device) in order to pass information back an forth. I've tested it with MiFARE 1k tags and the HOX works just fine.
There's a cool app that can read standard & non-standard NFC tags like the ones in credit cards and ones that stores use for loss prevention. It's called NFC ReTag on the Market (errr.. Play Store..w/e).
Others like NFC Reader/Writer by NXP are designed to work only with NFC tags that are NFC Forum compliant or of certain/most MiFARE types.
What's the range on the reader? I thought I read 10cm (4 inches) somewhere? I wonder if it'd be possible to get a wrist band with an nfc chip in it that would unlock the phone when you're holding it in your hand, but then require a pass-code if the wrist band isn't present. Could be a silicon band like people get for the various causes they support, or even integrated into a watch band (for the few people who still wear those!)
Another possibility would be a ring, that would definitely be in range of the reader I'd imagine), though I'm not big on rings myself...
I can definitely put my credit card up against it and it'll read it. It took a few seconds though.

I tried NFC Task Launcher and it's definitely a nice app, but with the switches you have to tap the tag twice. And the tags can only be read when the phone is unlocked. Hoping a chef can fix this in a custom rom.

To use Android Beam, you have to have the app open from which you wish to share information. Bring the phones together and tap the screen. There's no way you could ninja someone's data without them knowing, as they have to push it to you, rather than you pulling it from them.
EDIT: Oh, and yes NFC works fine for me, at least to push contacts via AndroidBeam.

As long as you don't go around letting people touch your phone to their phone you should be fine... NFC literally needs to be right up against another.
Or just keep NFC off it you don't trust it.
This is such a farce. This is how NFC works - the radio is activated and an action is taken. The worst they could probably do is send you to a page where you *could* download something malicious if you were ignorant in what you were looking at. I can see how scanning an NFC tag could force a download depending on the URL provided but I don't believe there is any way that this action will install something without the user's knowledge. You might as well say that you can "hack" Android via the Internet because in his example, he used NFC to prompt the phone to go to a particular webpage.
You want to talk about insecure? How many people still carry around house keys?
Wear a tin-foil hat or trust technology.
Me I rather have convenience technology gives us and will offer
In other news, your wallets with all your CC info can also be stolen by a hacking technique called "pickpocket".
Jokes aside, all this means is that Google will have another patch out soon. Oh wait, too late. Already fixed in JB.
Remember Bluejacking? Nothing like sending a (harmless) "your phone has been virus infected" message to a train car full of commuters and watching all the faces. Ah, the good ol' days...

Right, when I've played with NFC, the tag has to be close enough to almost touch (with millimeters) before the phone reads the tag. And the way NFC normally works when I've used it, the phone has to be screen on, and off the lockscreen. Unless there is some way around this?

Just to update, I received my order yesterday and they work great! Quality is impressive, and I was happy to see they use 3M adhesive.
Now, to come up with some cool ways to use them One idea I have in mind, is opening up my ultrabook and sticking one in the space beside the trackpad (doing it internally, not to affect the aesthetics of my new rig ), so I can tap my phone to initiate an ad-hoc connection to wirelessly transfer files. Not sure exactly how to execute this idea (or if it's even possible, both technically or without causing interference), but I'm going to look into it.

Plenty of things to do with it. From inducting night mode when you put your phone on the night stand next to your bed, to launching apps on your phone when near. My current task is set my phone to wake up with hoovering my hand over it when I'm on my bicycle. to define 'on the bicycle' you would have to stick the tag to the bottom of the mobile pouch for bikes ...

That's great to hear!
It's a neat idea to integrate a NFC tag below plastics or other non-conductive surfaces. Let us know how we can help with your project and since you do have an ultrabook the material may likely be metal. Not all metals will allow the signal to pass through so be aware of this.

Pair a bluetooth device, use it in your business cards, serve an advertisement with NFC targets, set it to call your mom, have one that texts your girlfriend that you're not available tonight, make a task that tells your wifi thermostat to turn off the A/C, set one to send a Wake On Lan command to your computer, etc...

Question can the tags toggle? If I tap it, it'll do something, if I tap it again it'll undo what it did or do I need two tags now?

Nope. You only need one tag. Toggling is entirely something you set up.
How is the business card idea working?
Also, something useful for me would be after touching one tag next to the door, to arm my ip camera, through the application that I have at my phone. Would this be possible?
Also, is there any site with normal round tags, with low price and shipping for European countries?

It works great for me but it does cost a lot more to give out business cards with the tags on it but I think it makes a good impression. I'm not sure about the IP camera thing though. I know it can be done but I don't even know what IP camera you use.
Also what's the difference between the round tags and square tags? Is there any performance difference? I find that the square ones read a lot faster than the circle ones I've ordered on eBay. It's seems to be a bit more responsive but it may just be the difference between Tagger's quality vs. eBay. I also ordered some on AliExpress but they were complete junk.

using s3 as a NFC access card

I have an ISO 14443-3A NFC access card for university and im looking to use my S3 Frontier as my access to class and purchases on campus. i know the watch has nfc capabilities but is this possible?
I'm guessing it's possible, but you would need a custom app, and probably with root privileges.
The standard use is by Samsung Pay, which does not even replicate your existing card NFC but creates a new unique one instead.
I have to admit that this would be pretty cool, however. Things like transport cards etc which are becoming ubiquitous. There's definitely a market for this for an enterprising developer!
Do you know if there is any code documentation for that? On how to access the nfc in my gear s3 to emulate an nfc tag? Any documentation on tizen nfc?

NVM - I actually found the documentation. I am going to try and code this, oh boy, that's going to be one hell of a challenge

Me? I did. Mostly just researching right now, didn't wanted to jump the gun and start before knowing if this is even remotely possible for me. It's definitely more complex then I expected, luckily I have some nfc knowledge, so this should come in handy. I also tried to find out if someone ever tried to do such a thing, had no luck with that though.
I guess the next step is to just build a custom app that utilizes the nfc in the watch, like a very simple app to learn how to work with it, and then develop it further to somehow magically pull it off and send the data of a copied tag from the watch to a reader.
I think it's possible though if I put in enough work, even if it's a bit out of my league tbh.

Me? I did. Mostly just researching right now, didn't wanted to jump the gun and start before knowing if this is even remotely possible for me.

Hopefully you find help because this is a much needed app. I would love to not carry my badge everywhere if i could have it in my watch and phone. Keep us updated if you can!

Thanks, though it's more complicated that it seems (Or that I though). I run into the same issues as some other a while back, not sure how to fix it, they never found a fix either, or at least they never posted it. It feels like a problem with me using a non rooted watch, because some operations of the api i am just not able to execute right. Guess my next step is to try it with a rooted watch, maybe that solves one of the many issues

Did you continue with a rooted watch?
Nfc
I'd be interested in this too if you can make it happen. Goodluck!
Curious progress check
Hi I'm also interested in having an app that can emulate nfc tags like the nfc mobile app...
I did find this site if it may be of any use.

I wish you luck with getting it to work
Hi, just wondering that did you make an app for NFC tag emulation eventually? Just got my new galaxy watch 3 and found the option with "choose an app to open with NFC", with Tizen os 5.5.0.1, it seems that Samsung has open the NFC permission for users.
