Need some advice.
At my work place, I have an ID card that I touch against the sensor on the wall which let's me into the office. I also have a separate card that opens the car park barriers.
Is the a way to get the info off the cards into my phone and use NFC via my phone ?
Exactly what I want to.

The problem may be that those scanners and those cards may work on a different frequency as your phone's NFC. Does your phone respond to either card when you bring them together?
You can't emulate nfc card like mifare 1k with most phones...nexus S was one of the phones with possibility to emulate some cards...

I looked into this a couple months back. The key card/key fobs work at a different frequency than the NFC antenna on your phone is capable of receiving.

Is it possible to attach two sd cards under the back cover somehow and either use them simultaneously or switch between them without openning the back?

yeah sure and you can also make your phone shoot lasers through the front camera.

Buy an SD card twice the size of your original
Problem solved
This is the most awkward question ever.....but now I know where to keep my spare
sd card....between the battery cover and battery.

I believe xplay does not recognise more than 32gb - that's the problem I'm trying to solve. Or am I wrong, can someone confirm if 64gb works? Thanks
Sent from my R800i
64GB means it is a sd xc card.I believe that all phones only support
sd hc cards....meaning the highest capacity would be 32GB...maybe when xc is more common, we'll be able to use it through firmware upgrade.

At my college dorm, we use a certain type of lock in which we put our keys up to the lock, and it unlocks. I figured it used NFC, but I wasn't sure. Then I found this article.
androidauthority/forgot-your-olympic-hotel-room-key-use-your-s3-103325/ (NOTE: As a new user, XDA won't let me post outside URL's. Type in .com after droidauthority for the link to work)
I've got no clue what kind of hardware is in those locks, but I can say that it looks EXACTLY THE SAME as the locks used in my school. For me, that essentially confirmed they use NFC. I don't know who makes those locks, but my school uses the same looking handles and lock mechanism. When the card is held up to the lock, the lock flashes green. If I had to guess, the card acts as an NFC tag. When held up to the door, it will activate my card as any other NFC tag, verify it's me, and then let me in.
Using NFC on my phone, I was wondering if it was possible to do the same! From a logical standpoint (not a dev's standpoint), I would need to somehow steal the info off my card, have it stored in my phone as a usable format for the lock, and then I should be able to just hold the phone up to the lock to have it open!
You guys think this is possible? How would I go about doing it?
sorry that i don't have the answer, but i had this same idea! also wondering if it's possible.

I dont think these use the same frequency. Here in my office we use the HID Prox cards, but its not the same, the easiest way to know if you could do this is get the NFC tag reader software on your phone and try to read the card/key if it will see it I would think you might have a chance, if it doesnt see the card to read it, its not the same and you will not be able to do this.

from what i've read...
doing what you're suggesting would pose a major security threat to all electronic door locks around the world. you're essentially duplicating your electronic key, which is not unlike duplicating an old school lock/tumbler key. unlike a traditional key however, this is an electronic key which means if you're able to duplicate it, you're also able to send/share it with friends around the world. in other words, we can set up a database of all the dorms / offices locks around the world and we can all have free access. doesn't sound like a pretty picture.
in reality, what our phones are capable of doing is READING the NFC tags. so if anything instead of thinking of your phone as the key, your phone can do the exact same thing as the lock, which is read the info off of the NFC tags. i know we have the ability to WRITE info onto NFC tags as well... but as others have posted there are issues of frequencies and i believe encryption which I HOPE makes this not possible for my security sake.
I'm sure if its physically possible(frequency wise) someone will make it happen. Its just like droid sheep, air crack, wifikill and the likes. Doesn't make it right but throw the technology out there and someone will make use of it.

I was able to do this with bluetooth and my Samsung Note 3 on Windows7. Got windows 10 and *poof*, it's gone as a bluetooth service. Now I'm scratching my head trying to figure out if that was a function of the BT dongle software, Dell security tools, Windows 7, or what!? A little off topic (not-NFC), but I have the same functional objective.
Just wondering what tasks people have set up for their NFC tags?
I've got 1 by my front door so when I'm going out it turns my WiFi off and my mobile data on, and vice versa when I come back in.
My other tag is at the bottom of my stairs so when I'm going to bed it puts my phone on vibrate and turns off WiFi, and vice versa for when I get up.
I've got 3 tags left so just looking for ideas how to use them

What is the range at which phone detects that tag at the door/stairs? Was thinking about getting those myself too
The range isn't great, about half an inch but that's all you need

Biggest let down for me is that screen must be turned on for nfc to work. Means you can't use scan tag as you need to unlock device first.

I'm using the mod so I can use them on my lock screen, all I have to do is press the power button and jobs done. Still quicker than unlocking and going to settings

I haven't used the NFC Tags yet, I like the idea of them... but personally find that implementing them as a 'time saving device' into my everyday life would be more hassle than it's worth.
If the range was say, about a foot and a half, so that it stopped my WiFi and turned on the Mobile Network as I left the house and I could just have the phone in my bag/pocket then that'd be amazing, but as I'd need to remember to locate the tag, press my phone against it, make sure the screen's unlocked... it's all too much hassle for me.
But as I haven't used it yet I can't really comment... Just my 2Pence

There is the mod to use tags without turning your screen on but I don't like that idea for security reasons after I watched the documentary about hackers/fraudsters.
They have converted their equipment which scans for NFC enabled bank cards to scan for NFC enabled phones, all they do is walk around busy places with the scanner in their pocket scanning away.
So with the range only being small and me having to at least be on my lock screen should keep me safe

So I got a slightly pre-used S3 T999 on eBay (decent deal at $435).
I cut my regular SIM card to fit in micro SIM slot (said card was from my T369, worked fine in temp/lent Galaxy Exhibit 4G). Cut card isn't being read....... ok fine... except, card won't eject....
Grab tiny tweezers to get card out......card comes out..... so does tiny sliver of gold connection piece...(tried to get a photo but it's really difficult with the angle).
Awaiting arrival of proper micro SIM.
If I need to though, I found Sim Card replacement modules are sold. However pretty much all I've found list being for the i9300. Are the modules interchangeable? If not, where can I find one compatible for the T999?
Thanks!

Hah, I was overcome with a very sick feeling when not only the card appeared stuck, but when the sliver of gold came out with it...x_x
Thanks for the confirmation on the compatibility, hopefully it won't come to it but I'm confident in my taking apart and putting back together skills (I think the issue with the card was that I was far too tired to be doing it then... but NEW PHONE MUST DO NOW! came over me).
Well the micro SIM came yesterday. I inserted it into the s3, and it read it (had yet to activate it).
Today, I activated the new card and.... the s3 continues to request that I insert a sim card. I waited the 2hr period of time for things to transfer, and soon enough the card in the Galaxy Exhibit 4G, was no longer working. But the new card still wasn't being read. I tried to use the new card in the Galaxy Exhibit 4G.... and...given a few moments,......and that worked. Even got text notifications from T-Mobile that "The SIM card for ***-***-**** has been updated.
Based upon that... looks like I'll need that replacement module (why it recognized the card before... I have no idea).

Tedious things such as micro connectors and small slivers of metal can be very touchy. So the prong prolly sat at the right place for it to make contact. Then once removed, the pin moved causing it to no longer make contact.
I havent had my S3 apart due to me still having warranty, or else id give you a hand. I had my S2 apart and the module seems simple enough to replace. I dont see a huge difference would be made within a year of how they work in each phone. I am sure there are some youtube vids or pics of someone doing it

Yeah, I more than likely got "lucky" that first try... At least I know what the issue is. It's not the phone, and it's not the card... just the connectors which I so lovingly screwed up. :silly:
Yes, I reviewed a video on how to replace it and given that I've worked on electronics with teeny-tiny parts before I'm confident this shouldn't take too much time. Just bought a replacement part for $7 (could have gone cheaper, but delivery would take longer from Hong Kong... so I went for the auction in the state next to me) and hope to get it by Saturday... or Tuesday given the ETA.
Once it's replaced, I'll post an update on the status of it working (or not...).
I seem to have run into a slight snag.... the sim/sd card casing isn't held in place like the vids show....(and by "vids" I mean ... well I can't link them but "Samsung Galaxy S3 i9300 Disassembly & Assembly - Drop Test Repair" and/or "Samsung Galaxy S3 Dis-Assembly Replacing Sim / SD Card Module SIII GT-i9300" on youtube).
*edit*
So I removed the actual holder from the metal part. There was some double-sided tape (none the likes I've ever seen before...please let me know if there's some similar tape!), which got a bit messed up (as I had no idea it was there) upon removal (which I pried it off gently with a micro-flathead screwdriver), but I managed to fix it up as best I could (thin portions wouldn't untangle/smooth). I placed the new holder upon it, but saw it wasn't going to stay put (inserting the sim card to test was enough to almost push it right off, and would have if not for the connector ribbon!).... so some bits of electrical tape are keeping things as secure as possible.
Phone appears to finally be able to function as a phone! :good:
Well I'm impressed. I would never attempt something like that. There's a reason I buy my phones new and have handset protection.

Why didn't you just go into a T-Mobile store and get a new micro SD card? I mean that seemed like the sensible thing to do. I was in your shoes and needing a new SIM card and they gave me one for free when I went into the T-Mobile store near my place of work. I just had to manually enter my contacts was the only hang up. No big deal though.

I used the card-cutting method because I wanted the $30 100 min/5Gb plan and it seemed like the easiest way. Ordered a sticker template for $1 on-line and cut it out - worked great, SIM pops in and out like normal, no problems.
As for a more secure tape/glue, my first concern would be if the original was intended to disperse heat and if so, how important is that feature to the phone's operation ?
If that wasn't a huge issue, I'd look at 3M double-sided film tape or even very careful, very tiny dobs of E6000 (I like it because it's pretty secure and still generally peels off easily if necessary) - concern here is making sure you don't use so much that it oozes everywhere and into something important - best to apply to the card holder, spread it out and let dry a bit, then stick the two together.
Making hardware work certainly is a feeling of accomplishment - it's like "yeah, look, I did that" - kind of like a kid, except a lot less expensive and you can't go to jail if you brick it.
Hello,
I use a magnetic card "NFC" to access my work place and sometimes the card like to get lost. I've seen a guy using his samsung as a replacement for the card, but refused to tell me how!
Is there anyway to get this thing working using the LG G3 as I'll be getting one soon?
The card type is Mifare 14443-A3 as scanned using some phone
Can anyone help in this thing?
