Mifare ultralight c // Authenticate?? - NFC Hacking

Hi XDA colleagues,
I just bought a Haloband it is a sillicone band with 3 nfc tags in it. The problem is the Haloband company failed and stopped selling and their site is down. But inorder to activate the NFC tags you need to download their app and scan the tags and register after that you are able to write and use the tags. But you can't register because the site is down so you can't use the tags.. But i tried Formating and Erasing but it doesn't work and i found out the tags are Mifare ultralight c tags that need a certain authentication. It is probally in the tag or their is probally a different way to unlock the tags.. Can be sometihing in the app data aswell.
Please someone that is smarter then me help me to unlock or erase the tags.
Thanks in advance.
Kind regards,
Robin

Anyone has an idea?

[Q] NFC tag bulk writer

Hi all,
Wondering if anyone knows of an NFC tag writer that can write tags in bulk? Im needing 250-500 identical tags written very quickly and the Task Launcher can only do one tag at a time.
Had a look around but the tag writers I've seen online only seem to do one at a time.
Any help I'd be grateful!
same problem
Hi, did you find any solution?
I have the same problem.
Tnx
GoToTags Encoder
Hey.
Check out the GoToTags Encoder. It's great for encoding lots of tags with the same data or different data. There is a trial that you can download from the website.

Nfc bulk writer
Hello,
If you need to write tags in Bulk you can try "NFC Bulk Writer" on Play store (I can't post the link).
You can also write different tags. You only have to import the csv with the list of tags to write. :good:

[Q] NFC card emulation

Hi
I am creating an NFC based solution and i need to send some information from a Nexus S to a desktop (windows 7 with ACR122 NFC Reader) via NFC. I have tried to do it using the P2P mode but i didn't find a way to read those information using the NFC reader.
And since it'is possible for the NFC to reader to reader MiFare NFC card , I need some help to know how is possible to emulate MiFare Card?
Which ROM enable NFC Card Emulation ? And how To Do it ?
Thanks

I wanted to do the same thing some time ago, but found out that without access to the NFC secure element in the nexus s, this is not possible. Apparently, the 2.3.5 updated for the nexus s 4G has access to the NFC secure element... cant confirm this because I dont have one..
Any updates on this?

i use an access card to get into the office at my workplace. would be cool if i could clone my card, however i dont think that is possible (security reasons). However if i had admin write the data to my nexus s NFC im sure it would be possible
Access to the SE is VERY limited. There is no public access to the SE currently.
AFAIK full Card Emulation is not in the SDK either (and may not be from an API perspective). Google in the past has cited issues with replication of all card technologies as well as lack of existing standards for emulation. They prefer to fall back on NDEF push at the API level. There is a bit of card emu stuff in the code base, but that may be related solely to payments / loyalty cards and it's not in the public API.
Thanks krohnjw - I was waiting for you to chime in. Keep us informed, if you don't mind.
Would be nice to get my transit pass on my phone...

Use Android Phone as NFC Tag?

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.

Hi i believe NFC ReTag will do the trick , or at Least NFC TagReader , can also be use as ask … but that will depend on what you will store in … as you didn’t say it ican’r help you more at this stage.
hope that help

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.

anyone trythis
ive seen the video after flashing and kinda dissapointed
bcos they cannot prove that nexus s can be the nfc tag anyway they donk have the reader too to test it
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) ?

Reading/Writing MiFare Ultralight on Nexus S (ICS)

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.

Copying NFC tags?

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?
