So would this nfc really work? - Samsung Epic 4G Touch

In theory, sure. It's along the same lines as SDHC cards that give Wi-Fi ability. The real issue is whether or not it's worth it to forgo the extra storage space of a memory card in favor of a NFC capability.
The concept of NFC is really cool, but isn't there yet in terms of practicality. I only use 1 credit card so, for me, having to use my phone to do transactions will more than likely take more time than just using my credit card. There are security benefits to NFC as thieves won't be able to steal information from the magnetic strip.

I actually am worried this would make things less secure than currently using your credit card.

Here is what I found on there site
Will I lose data on my original microSD?
No. The great thing about moneto is the fact that the microSD doubles as a storage source on non-iPhone smartphones. If you have any data or media, such as application folders, music, videos, or pictures on your microSD that you’d like to keep you can easily transfer that content to the moneto microSD.
* * Transferring data from my microSD to my moneto microSD
Load your microSD onto your computer. You can do this by using a microSD to USB converter, a microSD to SD card converter with an onboard SD slot, or by leaving your microSD in your phone and connecting your phone to your computer via USB cable.
Copy all desired files from your microSD card to the new folder. Simply drag and drop the files or folders you wish to transfer
Right click your microSD card and select “Eject” to safely remove it
Insert the second microSD card as you did in step 1
Copy the files you moved in step two and paste them in the moneto microSD, eject the drive to safely remove the card. Removing the microSD without ejecting on your computer or unmounting on your phone can damage any data stored on the card.

My thoughts on it being less secure would be if someone has a receiver for NFC, they could access your chip. There was a news story here in Denver, I don't remember the station, where they went yo the airport with said receiver and started pulling up information from people with the NFC credit cards. I have no idea if that would be an issue on phones, as I have not done any research on it, so it may not be an issue...

You have to actually load an app and do an authorization in order to make a payment with a wallet through NFC.

I am trying to think about the hacking possibilities. Also when you think about credit card theft, cell phone theft is also pretty high. For example, if you have an NFC sd card, and your phone gets stolen, how easy would it be to hack in and get the pin and have access to everything?
I haven't learned enough about it though, I could possibly be mistaken/misunderstanding/paranoid.

How would you get the Google wallet app on your phone if u get this? I love Google wallet and use it all the time withmy nexus.

That's more likely with RFID chips (the kind new passports have), not NFC. NFC has a very short range (literally, a few cm's) and as another person mentioned, you need to initiate a transaction for it to even show up. The only way they'd be able to do that would be to try and hijack the payment terminal itself since the range is so short. And even then, I'd imagine someone would notice if the card didn't seem like it was going through, but the customer was showing that they paid or it looked like two charges were trying to be made.
Security wise, NFC shows a lot more promise than RFID. It's really going to come down to how fast it expands (currently only uses MasterCard PayPass system and not all stores have those) and whether or not it's more convenient to use compared to traditional payment methods.

I had one of these for my HD2 for years (well, one year..) and I loved it! To answer the question, it did make me feel everything was safer because I'm always aware of where my phone is. I'm tempted to get one for my sgs.

That's specifically what this case was designed for. Octopus/Felica/etc. The "credit card" was someone making stuff up to try to sell it in places where contactless cards are not the norm.

Just to the point like for public transport in Holland and France they use NFC transport payment cards..
Still it does not matter people tend to level the phones, wallets , passport in public places on a daily bases. So stop going on about credit card in this case if you feel to put your credit cards in the so be it...
I have one of these. I use it to keep my business cards in. Also that means if I lose it the person who finds it has my contact details.
people who put credit cards in it though are grade A clowns though.
Could be very useful to put my ID card in that we have to touch against pads to open doors...
On the other hand, I like my phone naked
Thats quite cool, I'm looking for something similar to put my Oyster card in.
oyster card is a rfid card used to get thought barriers on London Underground.
I don't really see a problem with putting a credit card in it,I have more chance of losing the card on its own than loosing the phone with the card in it.
I thought of getting one of these: http://www.amazon.co.uk/GADGET-SAMS...?s=electronics&ie=UTF8&qid=1324822612&sr=1-14 but I hate think having to open it to use the phone would piss me of quickly

I'd have to agree, going to get one for my oyster transport card as I always have my phone handy so it makes sense.
Also I've never lost or had my phone stolen in 10 years but I've lost credit cards (and wallets) in the past so for me it's probably a safer option!

[Q] Use Gnex as ID card

I want to know if its possible to read my contactless work ID card with my phone and then use the phone as my ID by tapping it to the reader.
I don't know if this is even possible and my question isnt about the Nexus as much as it is about My ID card, but if anyone can help me figure out what kind of ID card I have and how that would or wouldnt work with the hardware in the Nexus, I'd appreciate it.
Thanks.
There is some sort of chip in your ID or is just a bar code you're trying to scan?

Some sort of chip. I tap the card to the reader in the elevator and at the front door to the office.
I don't even need to tap the card directly, I keep the card in my wallet and tap my wallet to the reader and it picks it up fine.
Let me know if I can provide any more info.
Thanks
I can't think of anyway to extract the information from the chip, but you could always cut the chip out and tape it inside the battery door. I wouldn't think anything would interfere with the chip, but I guess would might need to have an undamaged ID card.

Yeah, that wouldn't work, it doubles as a picture ID as well so I would need to keep it undamaged.
I've seen apps that read and store data when tapped with a credit card, so I was hoping someone would be able to provide similar info for how to do it with an ID card. I don't know enough about the different NFC and RFID technologies and what the nexus is capable of. Was hoping someone on here might be able to help.
Check out this thread from a few months ago. People came to the conclusion that it isn't possible.

From what I understand, data that's on most RFID cards is encrypted and the NFC antenna on the Galaxy Nexus (and Nexus S) is not currently capable of interpreting the data. It certainly seems that the possibility is there though seeing as how they usually operate on the 13.56 MHz frequency.

I posted this on another thread, but I think it is worth it here also. HID is beta testing using NFC technology for card access with Blackberry devices. Youtube HID Global Pilot Arizona State. NFC uses 13.56Mhz frequency. The HID iClass readers should work ONCE HID gives the customer the ability to get the software used to tether the phone to your computer and connect to the "secure" part of the Android OS and create a credential. It is coming. Just waiting on HID Global to make it happen.

OV-Chipkaart

Hello people,
So I recently was playing around with some NFC apps, and I found out my OV-Chipkaart (Dutch public transit card) was read by my phone. Unfortunately I got a lot of numbers and stuff I didn't understand. Does anybody know more about this?
The card is encrypted. If you get the key (there are a couple of articles on the internet which tell you how to get it), you should be able to read the entire card. Without the key you can only see the expiration date.
I saw it was possible to add your own MIFARE key in the TagInfo app. The only thing you need to get this key is an RFID-reader for your PC and some processing power (and the appropriate software).
cool
Thats so cool
My acces card for school does the same. Found this out because everytime i put my phone kn my wallet it made a sound.

UID
Each contactless chip (incuding the Mifare you have) has a unique id which is accessible to any contactless reader, in this case you phone. Unique id enables the reader to overcome collision for reading one chip at a time. This is is probably used as the id of your card by the system it is being used.

i tested it on my personal ov chipkaart but it didn' t work because i haven' t made a dump off the card. i haven' t got a reader for it so maybe if a xda that lives in Rotterdam/Cappele a/d Ijssel is kind enough to make a dump for me
I also recently checked my bus-card and the phone could read some of the info in the card, so i was wondering if it is possible to clone the info in the card to some other nfc tag, which would be cool, and also if i use the phone as rifid reader, mentioned above, connected to pc with usb then theoretically it would be possible to reprogram the card...?
And also another question, is it possible for the phone to send out same info which is on the card so i could use phone instead of bus-card at the bus?
EDIT: I read previous topics and realized that this is impossible.
The ov-chipkaart part is now available and working in the source of github/wandcode/farebot. I have tried and confirmed that this is working. You will need to crack the MiFare classic keys first, this is only possible on a ov-chipkaart by NXP-semiconductors (so not the Infineon version)
I don't have a RFID card reader... Is it possible to dump the chipkaart keys with the Samsung Nexus and then crack the keys with the PC?

No that's where the power of chip-cards come in play. There are no keys on it who a external device will receive and decipher. A Mifare Classic card has a built-in authentication system which you will have to pass to read/write onto the card.
The only possible way i could think of is to take the known key from the card, generate a dictionary on a computer and then bruteforce with a phone. But i think that would be more time/hassle then buying a 20 dollar NFC reader.

No Mifare classic stickers can be very small, and then again you can also attach it to the card holder it's in and when you get asked to take it out you just have bad luck. Though i am more interested in the Tech and Security rather then abusing it.

The sourcecode of Farebot is avalible on github if you didn't already find it.
Since it can already read the data it must not be hard to be able to write it back to a new tag..

[Q] External NFC Reader?

Hi
Is there a way to use NFC on a phone without NFC included (such as the Galaxy S i9000)?
I have thought about this. If a company would dish these out, it would probably jump start nfc usage and they would make a killing from it I bet.
Just a small tiny dongle that went into the micro usb port and could read nfc. I doubt supporting wallet would be secure though, with a physically "removeable wallet" in that case... but it could still read and write nfc tags.
I could see a market for this for sure...

External NFC readers

I found out my phone doesn't have NFC capabilities (Samsung Galaxy S2) and I hear there are external readers available that use the sim card slot or SD card slot. I was wondering if anyone has tried them and if there are any limitations compared to integrated NFC on a standard mobile phone.
I'm doing a project on NFC and its basically buy one of these or get my hands on a Nexus S.
Careful there buddy, your confusing things. What is it you want to do? Do you want to use your phone like a card, or do you want to read other cards? Either way, if your phone does not have any nfc capabilities, then that means you have neither the nfc antenna, nor the nfc controller, nor a secure element. The only way to get NFC capability to a non capable phone would be to use an sd card that brings all the components I just mentioned with it. I don't know of any company to currently sell that.
But before you go running after a new phone, be warned, if your project has anything to do with using your phone as a card, just let it go. Not worth buying a phone just for that as your project may probably fail.
My project deals with reading data off a card, altering the data and either writing the new data to the card or emulating it.
Are you saying this isn't possible with the SD readers or current phones ?
You could try to find a NFC-enabled battery for your S2.

Reading and writing to a card is possible as long as it complies to the nfc forum specifications. That means your phone can read most of the NFC Forum Tags and cards that generally comply to iso 14443 A or B. Some of the phones can also write Mifare Classic cards. It basicly depends on the NFC controller inside your smartphone. Smartphones that use NXP's PN544 chip for example have the capability to read and write them.
As for the SD, this is rather an open case. Adding NFC functionality to a non capable phone is not that easy to acchieve. In most cases you ned to equip your phone with secure element, nfc controller and nfc antenna. In order to do so you need hardware that basicly provides all of that. I read about some microSD cards that may bring all the components, but I haven't seen anyone sell them. It's definitly easier to buy a new phone that has all the capabilities you need.
Emulating a card is currently a dead end for third party devs. Unless you can talk to one of the big players like MNOs, TSMs or handsetmanufacturer you will be out of luck. If you are ok with rooting your phone and loosing warranty etc. you can maybe get card emulation to work. An example for it to work would be the app simplytapp that is available only for users of the cyanogenmod 9.1 and 10.
