So how do these work.... - NFC Hacking

Just got a galaxy s3 and was wondering how this works. Do i need to open an nfc app to tag to allow my phone to read a tag?

It works by putting ur fingers on the keyboard and searching NFC tags or even better read the 10 1-2 pages threads in this forum

Well say

You don't need to open an app, the system asks you to select an app after you tap a tag.

I read that any NFC capable phone can use them.
Ok thanks for that info
Sorry to hi-jack this thread but I have tried this and I can't seem to get it to work. My wife has the Xperia S and I have the One X. I got the app Xepria Smart Tag and NFC Task Launcher (free version) but I cant get either to work.
When I turn on NFC in the setting and then scan a tag I just get a line that tells me a smart tag has been scanned. I can't then set what I want it to launch. Help on this would be great.
Thanks.

Opening a file with NFC tag

My apologies if this has been posted before, I didn't see anything though while searching.
Is it possible or is there and app out there that can program an NFC tag to open a files, say, a .PDF that is already on you phone?
This would be awesome for my line of work.

I think NFC Smart Q can do this.

NFC Smart q works great to open a file, but it is not compatible with the Nexus 10. Does anyone have any options for the nexus 10? I would like to open a video file that is on my nexus 10 using an nfc tag.
I am looking for the same thing.
I a trying to find an nfc app that can launch a shortcut of a file.
Specifically I want to open an e-robot command file.
Any ideas?

Warning: Lock Screen Bug

So for everyone using Jellybean stock, there is a bug in the lock screen, it allows bypassing without a password.
Most notably, if your phone is locked with auto rotation on (auto rotation seems to make it easier to do this) and rotate your screen to landscape mode. Click on emergency dialer and then the contact button. Hit home and then immediately power. If done correctly you have full access to the phone when you hit power again.
Lookout has tried to address this bug; however, their "fix" actually makes it easier to break in. By foregrounding the contact list it removes some needed steps to attempt to break in again. It can take several attempts to get the timing down. Once you see the home screen mash the home button to suppress their fix.
Keep your devices close to you. This is an especially nasty bug.

Thanks. Unfortunately I have AT&T and knowing AT&T they will flat out ignore it or wait forever to get it to us..
Why create one more thread? There is an already existing thread on this.

Searching for "lock screen bug" doesn't show a thread on the first couple of pages, it doesn't appear to be sticky or even part of the recent posts, so let me ask, where is said post?
And does it contain the fact that Lookout doesn't work?

So XDA's search really sucks then. Check the search link, it doesn't identify that thread. I wouldn't have started a new thread if I could have found an existing thread.

Lol... that's cos the thread above does not have tags mentioned in it. A search is optimized based on tags attached to it normally. Anyways, its cool cos your thread is in AT&T section while the other one was in International S3.

And I guess that answers your question as to why we needed another thread. The other threads are not easily found. I expect that this thread will end up in the heap with the rest of them.
When the title of a thread basically matches the search term, I'd expect it to show up, regardless of tags. Or am I expecting too much?

Motorola Skip on Other Devices

I have looked all over XDA and Google looking for an answer, so I hope I am not starting a repetitive thread.
I got my girlfriends Moto X in the mail today and she got a free Motorola Skip with it. She isn't going to use it, so I figured I would try and set it up on my HTC One. I can't seem to figure it out. Any suggestions, or tips? Has this been done yet?
would also be intrested in this

I'm fairly sure a lot of people would. I'd like the quick notifications feature too.
Assuming you know how to NFC, can you scan it with NFC tag info and post the results?
I'll have a looksie see how it works.
(Scan tag, email to yourself then copy/paste from the email)

Thanks for posting this, was just coming online to post the same answer. Interested in the results.
If its just a standard tag - doubtful, but who knows with googorolla these days - I have an app called nfcsecure that does a similar thing. Due to limitations of the framework, I can't actually turn the screen on, but its an NFC lockscreen.

[Q] Using phone as NFC key?

Hi everyone,
i have just purchased a nexus 5 after a long wait for its release, so i am now going to have an nfc enabled phone. I go to a university where we have nfc tags instead of keys and i would like to know if it would be possible to write the information from the nfc tag to my phone so i will be able to use my phone as my key so i dont have to keep taking my key around with me.
any help with this would be much appreciated, or if its just not technically possible at least it will have put this idea to rest in my head
Thanks guys

Thanks for the reply! Just got an email from google saying my N5 has shipped cant wait to try this!
Id be a bit concerned if my campus keycard system could be cloned by anyone with nfc on their phone. If your school is on their and puts some level of encryption on their system. Then again if they are at all like my school was when it comes to tech, clone away!
endlywi distinct
unfortunately the key is encrypted but got my nexus 5 so woo!
You might be able to talk to the person who runs the keycards and get them to flash your phone but id highly doubt they'd let you do it.
