Hi all,
I have a Samsung EZON door lock. The lock has rfid and uses 13.56mhz tags. I'm trying to figure out if it's possible to use my S4 to unlock the door. Anyone have any thoughts or ideas about this? Any help or information would be appreciated.
TIA
Wouldn't you just need some kind of app to do it? If the frequency and protocol is correct (hardware is compatible), I would think you just need a way to transmit the data. I assume there are apps for that. It seems to me all you need is an app to "copy" the data from the key and transmit it when requested. However, I have no idea if there is security in preventing the copy, if there is a random code change at each interaction (like a garage door opener), etc.
Try checking the NFC tag reader/writer apps in the play store and see if any of them will read the tag with the phone hardware. That would be the first step I would think.

Hi guys,
I believe that the NFC chip in my device (battery) is broken. I have tried two different NFC reader applications and swiped my library card, my RFID keyring for work and my gym card with no success. I turned NFC off and on, rebooted the phone, nothing.
Is there anything else I can do to troubleshoot the NFC chip? I want to make sure its a hardware fault before I turn it in.
I have unlocked the bootloader and rooted via superboot, and it's been flashed with yakju 4.0.2 from googles website.

Does NFC enable in settings? Capture a logcat when enabling.
Are you sure that the tags you are scanning operate on the correct frequency (13.56 Mhz)? If so capture a logcat when you try to scan the tags. Capture a logcat when trying to read a tag.
I know this might sound stupid but I'm being serious. Can someone actually explain to me what NFC is, how GNEX can use it and what can be done now with it? I just need it simple terms, searching it online just drove me crazy.
Thanks, appreciate the help.

Thank you for helping. Yes, NFC seems to startup alright according to logcat, no error messages or warnings when I do this. I also see messages "NFC-EE routing ON" and "NFC-C polling ON". The log is too long to post it for you.
I also tried logcat during scan but it didnt notice anything.
No, I am not sure that my tags are operating at 13.56 Mhz... Perhaps they arent. Have to look this up!
Somebody in Sweden knows anything I could test my NFC against?

NFC is for Near-Field Communication and is a wireless communication standard that only operates at a very short instance, eg. 1-4 cm. It can be used as a replacement for regular debit cards so instead of using your card when you go to the shop you just swipe your mobile phone against the shops sensors and enter your pin code to pay. It can also be used to perform a secure handshake, for example if I come to a friends house and I want to access his WiFi, I'll just swipe my phone close to his Wifi Router and they will pair and share the network encryption key. The security in this is that no unauthorized person should be able to get within 1-4 cm of the router to get the encryption key - and NFC simply does not operate at longer ranges then this. These are a couple of things I know are coming with the NFC technology, there's probably alot more stuff we can do with this. Oh btw, we got the Android Beam aswell!

do you have an extended non Samsung battery or just a non Samsung battery? Or is your battery exterior damaged in any way?

see if you can find someone with one of the latest nokia phones with NFC support, or is there any nokia show room nearby, you can try connecting their NFC/BT headsets.
Hi
Here at the university we use a NFC card to check in. Is it possible to copy the tag to my phone so I don't have to carry my student card around?
Depends

Hi Samuel
I believe this is not possible right now, as there are security measures in place to prevent fraudulent use, but give it a couple of months there will be apps you can download , to copy re-writeable NFC tags to your phone, making your phone work as an emulator of some sort.

To emulate cards with your NFC phone, you have to have full control of the secure element. In the Nexus phones, access to the secure element is restricted to Google - only they have the codes to access it. In non-Nexus phones like the SGS2, they don't even have built-in secure elements and therefore have to rely on SIMs, which are in turn controlled by operators. Without access to the secure element, you won't be able to emulate another card. So, no, even in a few months you won't be able to copy a tag and emulate it from your phone. Unless Google opens up the secure element to, which is unlikely.
To OP: Even if you could actually copy the contents of the card and then emulate it, this might not be enough. Many schools use just the UID of the card to associate it with your account on their system. This means that there's a good chance that your card actually has no data on it. Furthermore, phones aren't currently able to emulate UIDs. You're out of luck.

Clearly, a direction NFC will follow. There's no way users will allow something like that to remain as neutered as it currently is. It just (seemingly) has not worked that way in the past.
thanks
thanks
I'm not sure if the GN Near Field Communication (NFC) is the same tech as the Wiegand Proximity cards and readers we have at work. Does anyone know if it would be possible to have my phone transmit my key number so that I could use it on the door sensors?
I asked the IT guy at work and he was not sure. He told me our card readers are Wiegand Prox(imity) 126 bit readers. The access key card I have is broadcasting a number code which I know what that is. I was hoping to be able to program this number code into the GN NFC and use it as a spare access key card.
Anyone?
Jim
Android is not capable of card emulation currently.
OK thanks. By currently do you mean they have the physical capability but no software has been written? Are you aware of plans to add this in the future?

After looking around the NFC hacking sub-forum, i can say it's not going to happen anytime soon. I read a lot of post over there that says you need access to the Secure Element which is not going to happen(at least now)
OK well thank you for the answer. that is unfortunate. It seemed a nice addition to the phone's capabilities.

Should be possible on 4.4
I believe android 4.4 should allow this now:
developer.android.com/guide/topics/connectivity/nfc/hce.html
Unfortunately I've not seen an implementation yet
I have a project (NFC Vending machine) based on Arduino which calls a function called nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A)
Which returns a simple UID of the device that is tapped to the NFC antenna. This is used to identify the user, display their name and account balance, relay to coin acceptor and then saving the new balance back to an SD card.
This application works perfectly with my Nexus 4, a friend's stock Nexus 4, as well as any NFC Tag.
When I try using a new Galaxy S4 however, the application finds an ID from it, however it CHANGES every time it's scanned? Does anyone have any idea how to stop this from happening? I'm not opposed to writing an app if I can write an app that stops this from happening (some function in code that can set the UID to a static unchanging value, maybe using wifi mac address as a base)?
When I try scanning a co-worker's Droid DNA, NOTHING happens. NFC is on, beam seems to work, but nothing happens. I'm wondering if I install an app that reads/writes cards and tell it to perform an activity maybe that will 'wake up' the nfc chip making it active and forcing it to spit out an ID?
I have a feeling I'll have to use an "if id is not found, try ndef" and write an app that can send an ndef message that is the wifi mac address (so it'll be unique), though I haven't done much in the way of app development, though I'm very familiar with playing with all kinds of nooks and crannies in the filesystem to do fun things in android. I'm not opposed to learning, and have been trying, just not too familiar with java which certainly doesn't help... In any event, I'll be diving in and punishing myself with more hours of reading soon...
I realize this is a rather unique project and I may not find a resolution here but any ideas anyone can offer would be a big help. In the meantime I'll continue reading up on the various actions that are available to the programmer regarding nfc in the android sdk...
Thanks for any suggestions!
EDIT: I forgot to add, while I realize NDEF is an option (one that will require me learning a fair bit), it adds a great degree of difficulty in working with Arduino, which doesn't seem to have much in the way of libraries/code for handling NDEF, particularly peer-to-peer...
I'm moving into a new appartment, this is the key for the building it is in.
It says Simonsvoss on it, its the name of the company.
You just have to hold it in front of the lock and it opens automatically.
I thought maybe it uses NFC and you can read out the key and also use your phone as a key.
I tried some NFC reader apps, but none of them got any signal.
I'm not sure if NFC works on my phone (i have a galaxy s3 with cyanogenmod 11 M6 installed).
Anyone knows if this thing even uses NFC?
I'm no expert but it was my understanding that nfc is Bluetooth and these fobs use some other radio signal

There's a number of different reasons why your smartphone can't read it:
- it doesn't support that particular tag: it does happen, perhaps it works on a different frequency, or uses unknown protocols. There isn't much you can do about it.
- that key is not an nfc tag: it sounds unlikely to me, since the way you described how it works makes me think it is actually an nfc tag, but who knows.
- the cyanogenmod you installed doesn't support nfc: have you tried reading other tags with it? What kind of software are you using for reading it? Make sure you can successfully read other kinds of tags: if you happen to have Mifare Ultralight tags, you may use an app I developed a few days ago, UltraManager. if you have other kinds of tags (even the most recent passports have nfc tags embedded), apps like NFC TagInfo should do
- you have accidentally removed part of your nfc hardware accidentally: I know this sounds unlikely, and I would've never suggested it, but earlier today I talked to a guy who claimed he couldn't read any tags: turned out that he had changed his smartphone's battery with an unofficial one, and since that particular smartphone had the hardware on the battery, he obviously couldn't use nfc.
I know this thread is dead, but...Probably not NFC, since I can even scan and copy my Passport (hex codes of fingerprints and so on).
Would be to easy to break into a appartment secured like this

Radio Frequency
The Transponder is a radio transponder, it unlocks the lock by sending a radio frequency which cannot be cloned like traditional RFID ..
Simons-Voss stated this information on their website, in fact that was their main selling point is that the transponders cannot be cloned .. I know this thread is old and all, but I would be interested to know if anyone has figured out a way to hack these locks. I used them, so I am interested to know how their level of security is holding up after all these years ..
