Read Basic Tag Information UID, ISO, ATQ, SAK...
Share Tag NDEF only for now. (... not all ndef tags supported yet)
Create your own NDEF Tag... (... pretty buggy try to fix this next week)
Detect ePassport
Read Mifare Ultralight / C
Read Mifire classic 1K, 2K, 4K only with std. keys.
Future Features:
Card Emulation
ePassport
Android Market Link: (new version is in the market)
http://market.android.com/details?id=com.pocketluxus.nfclassic
Im interested in this, especially the emulation of NFC cards.
also your link is broken.

Link Fixed ;-)
I already have developed a version of this app with the new SDK, so the emulation modus should work there, but i cant test it without a software update for my nexus... damn google, hurry up and update GIT with the new NFC classes!!! ;-)
I am so hoping for a phone/oyster card merge in the near future, will be nice to leave the wallet at home ^.^
That is presuming it's possible. Nice to see some NFC groundwork allready being done. Should be an interesting year
is there a way to check if nfc is working correctly? i was not able yet to scan anything..i even don't know what i could scan here in germany
great stuff! cant wait for 2.3.3 (or whatever that has NFC api's), apparently we're getting an update soon (http://engt.co/eivVFI) with bug fixes, dont know if that has the NFC api's.
i have 3 RFID cards i want to use!!!!
@djbrutale, have you seen this?
http://forum.xda-developers.com/showthread.php?t=957104
this guy apparently has a i9023 with Android 2.3.3!!! and he also has a different tags application! may be you can test it on his?
Nice - Can't wait till all the features become available.

yeah, i have seen this...
but i have to wait for the update, i need it on my developer phone, otherwise i cant test it. Some rumours says it comes next week... so lets wait and hope ;-)
If you already have 2.3.3 u can check out the NXP version
https://market.android.com/details?id=com.nxp.nfc.tagwriter&feature=search_result
looks like they did the same work as i had planed :-D

does yours work like 'store - and - transmit'? i.e. scan my oyster in and use the phone instead?

I think i can only emulate Ndef Tags like SmartPoster, URLs...
If you have the Mifare Keys u could read out the card completely or change something on the card, but i think u will never be able to emulate a complete mifare card with the NXP chip on the phone... That would be crazy if NXP let that happen ;-)
My software will be able to share contacts and files via NFC.
Collecting tags like a SmartPoster and share them again with NFC.
Maybe i implement a full readout from the mifare cards with the std. keys, so if u have luck u can read whats on the mifare card, but i will be hard to emulate that.

Added a new feature. the complete payload of the mifare card will be read out ;-)
Well the emulation modus is a tricky thing, i guess... not sure if im able to get access to the secure module...
tried it - it reads, but some times says reading fails. and it seems to crash the settings > NFC switch.
great news about the mifare card readout.
is it possible to erase a mifare card?
Hello there,
is it possible to use my HTC One X as an NFC Tag?
My goal is to scan a normal NFC Tag (1k) with my phone and store the informations. And then I'll provide this informations with my phone, so an other NFC Reader can read the informations stored on my phone.
Greetz
It is possible as the NXP chip most likely used by the HTC (and known to be in Nexus S/galaxy) can be put into card emulation mode but the current kernel does not support it. There has been at least one user that has gotten it to work on the Nexus S.

I'd really like to do the same thing.. but haven't had any success in finding a way to do that. I would personally love to scan my work badge and use my phone instead of my badge which I commonly leave at home. It would also be great for hotels where I commonly lose my hotel key and could instead use my phone.
Any advice on these being a possibility. Any additional information I need to provide. I personally have the HTC EVO 4G LTE and my wife has the Nexus S 4G that I could use.
card emulation
try NFClassic.apk its in the android market, i cannot confirm it works but it appears to and i will test it tomorrow, it recognises my work card it picks up 2 tags, one will be door access and the other is canteen credit, (the app doesnt tell you this, but i know there 2 parts to the card, as i recently cancelled a card then found it, and can no longer access doors with it, but can still use it in the canteen) anyway the app reads the card and asks if you want to save the info, save it, the you will see it under saved tags click the tag, and click share tag, it then appears to emulate the tag as a card so it can be read by a nfc card reader, but i dont have a reader to confirm this, but i will try it tomorrow night at work to see if the doors accept it, ill let you know my results
and if anyone else know of any apps that can definatley emulate cards on galaxy s 3 let me know ! the more software i can try at work the more likely ill find one that works, i only got my s3 yesterday and have been of work so havnt tested any app, but NFClassic is the only one that appears to emulate my card.
note the app cannot write cards, only has options to write contact to card but when tried it force closes. i would definatly like to be able to write to card if at all possible ( free lunch copy card when it has credit , when run out of credit, re-write info = credit again its gotta be possible somehow ! )

NFC ReTag can´t do that ... but a lot of other cool stuff
I tried nfclassic and that didn't work I'm also looking for NFC card emulation
I'm not sure about other phones but Evo4GLTE's have Android beam that should do what is wanted
This didn't even occur to me til I saw this thread. I will be trying with my work badge since I occasionally forget mine as well...
I am still deciding between getting the S3 and the EVO 4G LTE. Leaning towards evo... but haven't played with the s3 yet.
I don't have your HTC, although there's documented info for the nexus s where devs were successful in emulating mifare most of the code is still on dev android. Its not full reigns of emulation but depending on your level of tech you can do some pretty cool stuff. I don't know how far this has gone but I remember people getting some functionality on new galaxy. Check out the link.

I was thinking the same thing!
The most "advanced" operations that i was able to do with the Galaxy Nexus were saving actions with differents cards. But that's all.
By the way, i use NFC ReTag to achieve it.
What I was just referring to was emulation how I perceived the op was looking for. Example you use a card at work to open a door and wanted to emulate that so you could use your phone instead. However with gwallet or say paywave then you'd need to have the secure key which obviously wouldn't just be given out otherwise you would be able to emulate anyone's card. Hence the secure element. Then it would be ridiculously insecure. Ex. If I took a friends paywave and was able to emulate it then now I in theory just stole their credit card . It's also why gwallet won't work without a secure element like on my sgs2.

Hmmm...
Hey guys.. i went searching in the marketplace for an app that does just that (emulate a RFID)...
And... I FOUND ONE!It's called NFC Classic Tag Reader
It was able to read my cards and apparently emulate it but i have no idea if it works cause my door does not detect it... and i have no other NFC devices...
I'm using a SHS-5120 door lock... and that only registers the serial no of the tags programmed and allows only those to enter...
Read on the comments that ICS users are not getting it to work but previous 2.3.3 user reviewed that it was working like a charm...
Oh and i'm using a S3... which of course is ICS...
I reckoned Google Wallet will store something into the mobile NFC chip. Make the phone like a RFID card or tag.
I also noticed some Korean telecom operators has their apps integrated on the Android phones which have the Membership card, Voucher, Credit card etc. functionality. That means the NFC enabled phone can be acted as RFID card or tag.
Is there anyone know where we can find the source code sample from Google development website we could look into this kind of project?
We have HID sensors on doors at work as well as a clocking in system and both use different cards so I'm going to have a go with them on Monday with my SGS3.

any luck with doors?
Anyone any luck with being able to push/publish his phone as a card? Like for instance with doors?
We have Mifare Classic cards which open doors, reading the card isn't a problem, but being able to emulate your phone as a card has proven to be more difficult..
How does one turn his phone into 'beacon mode' (being able to receive the door's power boost and return card info) ?
Just read this article
http://global.samsungtomorrow.com/?p=16659
The interesting thing is that they must have been using the hidden API to be able to use card emulation.
From my experience with hotel nfc cards they often are Mifare UltraLight cards.
Maybe they are giving out special phones using a custom ROM made by samsung that has this enabled.
I'm currently checking the 4.1 sources to see if anything can be done with that.
So what do you guys think about this? If someone with access to this phone could dump the rom it could be easily checked with the current S3 and see the diff.
This is interesting but I think we will have to wait. The article says only 40 VIPs will get it to start, the odds of any of them dumping the the ROM is slim to none.

All it does is transmit what was copied on the card via NFC. But in my experience most hotels don't use NFC yet; they still use magnetic strip cards, which by the way can still be easily copied. Just because they're encrypted doesn't mean you can't just copy the raw encrypted data to another card. Check this out:

I've been to several new hotels which indeed use NFC Ultralight cards.
I'm saying that, to be able to use this data you've copied from a card onto your phone, you need to be able to make the phone emulate the same card as the one you copied from. And that is the interesting part.
I'm working on a patch for 4.1.1 (galaxy nexus) that will enable this option, same as the phones used at this olympic hotel.
Google Wallet works in the same way, doesn't it? Card emulation is built into Android, but for an application (like Google Wallet) to use it, it must hold the access keys to the secure element.
Samsung controls the secure element in the S3; writing an application that can access the secure element is no problem for them.
Also, someone above said something about just copying the 'raw data' from an 'encrypted' card. You'll need access keys to access the data stored in each sector, so I doubt that would work.

yes, it's correct that samsung has control over who has access to it, but it's easy to "add yourself" if you patch the software.
About the keys for each sector, this is no problem because the ultralight cards dont use any encryption, even for the classic cards the protection is broken. So this doesn't really matter, the point is that people should be able to create their own cards inside the phone for their own usage for example.

I've succesfully copied and cracked a Mifare classic card, thus accessing all the data in the sectors. It took me just over 10 minutes for a single card. But my interest is also, how can I put this card dump file on my phone and let the NFC chip push/emulate this card dump as a Mifare card?

Is there any reason it has to be your phone? Could you write the info to a mifare tag, and get the same effect? This would allow you to clone the card to a paper sticker.

The Problem is that you can't change the ID of the card. Most applications check (only) for the ID as it is (falsely) seen by many as unique and unspoofable. So an card emulator able to let you change the ID as handy as a smartphone would be really really nice

But this feature is normally not accessible in the phones - partly also because of these reasons.
You would have to obtain keys to the ecure element from the operator or the handset manufacturer and will surely not give it to you if you are not a bank or someone of a similar size

Perhaps you could also try to use an unofficial ROM, but I am not sure if that solves the problem
In order to emulate MIFARE Ultralight, you need the first UID byte = 0x04. NXP Semiconductors have introduced a restriction in their interface chips such that UID0 is hardwired to 0x08, meaning "random UID" according to their specifications. So even if hidden Android API get released, it will still not be possible to use the phone itself for MIFARE Ultralight tag emulation. However, EMUTAG emulator on emutag.com totally solves the problem by being portable, and can emulate any UID with almost no restrictions* (see Manual).
yeah its right.. i agree with you
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.

There are currently no ways who are interesting for a non-developer. Start and do some research
youtube video of these codes coded into CM 10
these codes were originally in Nighty CM9 at around march 2012. it was then removed from the rom afterwards. these people at University of Texas has ported it onto CM10. these codes are pretty much the prerequisite of NFC proxy. which is a card emulation software, also work to proxy a card. and they have used it in the video to scan a card with phone NFC enabled phone, then the data collected is directly sent to the proxy. and allow it to simulate the card and purchase with the card.

Yes, but only in a state where it is almost only interesting for a developer's perspective. You can enable the emulation of a Mifare classic 4k card. And you can only write on it using a external writer and UID is fixed.

If what you're saying is true, and people are emulating Mifare 4Ks with a static UID on modern phones like the S3, then many people would be interested in using that to replace their door entry cards at work and school.

That is also true, but most mifare classic systems use authentication based on the UID wich is not to be changed externally. You can read/write under certain circumstances to the emulated Mifare classic 4k. But because it is a default applet, and we do not have access to the configuration of the card (Mifare4Mobile). I highly disregard using the feature because you might lose a correct dump of your mifare classic card.
But ofcourse, it is alot of fun. Sources are on the interwebs, http://stackoverflow.com/questions/12955919/enabling-cardemulation-on-android-ics-with-nfc-extras i have rewritten that code and it works.
Read again, when you are cracking a Mifare classic card and emulating it for gaining access to places where you do not belong without a proper card. you might get busted

That's not what I'm talking about. If, as you claim, you are able to emulate a card that has its own fixed UID, then that is highly useful. At my place of work, I'd be able to go to the IT guys and have them use my phone's emulated card's UID for my door access.
I'm not talking about shady stuff here.

Sure, you might be able to do that.

Hi,
Would you give me more information or reference about deal with "nfceeadmin" ?
For now, I got a security exception when I access the SE, and after doing some search, It looks like need to root my device. But I got same exception after root my nexus 7.
Thanks your help

Hi,
Thanks your help , but I still get same security exception.
Here is my step,
I am trying to use debug signature (debug.keystore) and modify system/etc/nfcee_access.xml like below
Code:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
<!-- Applications granted NFCEE access on user builds
See packages/apps/Nfc/etc/sample_nfcee_access.xml for full documentation.
-->
<!-- Google wallet release signature -->
<signer android:signature="3082...852e" />
<signer android:signature="3082...996ab">
<package android:name="com.rftag.cardemu" />
</signer>
<debug />
</resources>
After reboot my device and run test app again, the code throw exception at "nfcExtras = getMethod.invoke(null, adapter);".
And I don't see any message about NFCEE denied in logcat, Did I miss something ?
PS: for reference, My device is Nexus 7 and running 4.2.2 ( offical ROM, only rooted )
